Gasoline-OilRecommended Gasoline (CFR 1000/F5/F570/F6/Z1/Z1 Turbo Models)

The recommended gasoline to use inthese snowmobiles is 87 octane regularunleaded. In many areas, oxygenates(either ethanol or MTBE) are added tothe gasoline. Oxygenated gasolines con-taining up to 10% ethanol or up to 15%MTBE are acceptable gasolines; how-ever, on the F570 model whenever usingoxygenated gasolines, the carburetormain jet must be one size larger than themain jet required for regular unleadedgasoline. For example, if a 220 main jetis recommended for regular unleadedgasoline, a 230 main jet must be installedif using an oxygenated gasoline.

NOTE: The Z1 Turbo models willdetect lower octane gasoline andreduced engine performance willresult. It is recommended that 91octane (minimum) gasoline be usedin these models.

When using ethanol blended gasoline, it isnot necessary to add a gasoline antifreezesince ethanol will prevent the accumula-tion of moisture in the fuel system.

NOTE: On the 2-stroke models foroptimum performance, do notexceed the recommended 87 octanegasoline. Using a higher octane gas-oline will not increase overall perfor-mance.

Recommended Gasoline (CFR 800/F8 Models)

The only recommended gasoline to use inthese snowmobiles is 91 octane (mini-mum).

NOTE: For optimum performance,use only 91 octane (minimum) gaso-line.

In many areas, oxygenates (either ethanolor MTBE) are added to the gasoline.Oxygenated gasolines containing up to10% ethanol or up to 15% MTBE areacceptable gasoline. Do not use gasolinescontaining methanol.

CAUTIONDo not use white gas or gasolinescontaining methanol. Only ArcticCat approved gasoline additivesshould be used.

CAUTIONIf a situation arises wherein 91octane gasoline is not available, 87octane gasoline can be substituted;however, do not prolong the usageof 87 octane gasoline as it will causepoor engine performance.

CAUTIONDo not use white gas or gasolinecontaining methanol. Only ArcticCat approved gasoline additivesshould be used.

Recommended Injection Oil (CFR/F-Series Models)

The recommended oil to use in the oil-injection system is Arctic Cat Formula 50Injection Oil (p/n 5639-475 - qt) or (p/n5639-476 gal.) for F5 and F570 modelsor either Arctic Cat APV Synthetic 2-Cycle Oil (p/n 4639-349 - qt) or (p/n5639-469 - gal.) or Forumla SS Semi-Synthetic Oil (p/n 5639-470 - qt) or (p/n5639-471 - gal.) for CFR, F6, and F8models. These oils are specially formu-lated to be used either as an injection oilor as a pre-mix oil (for break-in) andmeets all of the lubrication requirementsof the Arctic Cat snowmobile engine.

Recommended Engine Oil (Z1/Z1 Turbo Models)

The recommended oil to use is Synthetic0W-40 Oil (p/n 5639-172 - qt) or (p/n5639-173 - gal.).

After the engine break-in period, theengine oil should be changed every 2500-3000 miles on the non-turbo models or1500-2000 miles on the turbo model andbefore prolonged storage.

Filling Gas Tank

Since gasoline expands as its temperatureincreases, the gas tank must be filled toits rated capacity only. Expansion roommust be maintained in the tank particu-larly if the tank is filled with cold gaso-line and then moved to a warm area.

Also, if the snowmobile is to remain on atrailer after filling the gas tank, the bed ofthe trailer must be maintained level toprevent gasoline from draining outthrough the gas tank vent hose.

Break-In Gas/Oil Mixing Instructions (CFR/F-Series Models)

Before mixing gasoline and oil, make surethe oil is at room temperature (20° C/68°F). Use a U.L. approved 22.7 l (6 U.S. gal.)gasoline container for mixing the gasolineand oil. To properly mix the fuel at a 100:1ratio, use the following procedure:

1. Pour gasoline into the gasoline con-tainer until approximately half full.

2. Pour 236 ml (8 fl oz) of the recom-mended 2-cycle oil into the gasolinecontainer.

3. Install cap on gasoline container andshake the mixture vigorously.

4. Fill the gasoline container with gaso-line; then cap the gasoline containerand shake the mixture vigorously.

5. Using a fine-mesh screened funnel,pour the fuel mixture from the gaso-line container into the snowmobilegas tank.

Engine Break-InThe Arctic Cat engine (when new orrebuilt) requires a short break-in periodbefore the engine is subjected to heavyload conditions.

CAUTIONAny oil used in place of the recom-mended oil could cause seriousengine damage.

! WARNINGAlways fill the gas tank in a well-ven-tilated area. Never add gasoline tothe snowmobile gas tank near anyopen flames or with the engine run-ning. DO NOT SMOKE while fillingthe gas tank. Do not sit on the snow-mobile without first installing the gastank cap.

CAUTIONNever mix oil and gasoline in thesnowmobile gas tank.

! WARNINGAlways fill the gas tank in a well-ven-tilated area. Never add gasoline tothe snowmobile gas tank near anyopen flames or with the engine run-ning. DO NOT SMOKE while mixingfuel or filling the gas tank.

CFR/F-Series Models

Arctic Cat requires that the first tankfulof fuel be premixed at a 100:1 ratio in alloil-injection models.

During the break-in period, a maximumof 1/2 throttle is recommended; however,brief full-throttle accelerations and varia-tions in driving speeds contribute to goodengine break-in. After one (1) tankfulbreak-in period, the snowmobile may betaken to an authorized Arctic Cat Snow-mobile dealer for a checkup. Thischeckup is at the discretion and theexpense of the snowmobile owner.

Z1/Z1 Turbo Models

This engine does not require any pre-mixed fuel during the break-in period.

To ensure trouble-free operation, carefuladherence to the following break-inguidelines will be beneficial.

* With occasional full-throttle operation.To ensure proper engine break-in, ArcticCat recommends that the engine oil andfilter be changed after 500 miles. Thisservice is at the discretion and expense ofthe snowmobile owner.

Drive Belt Break-InDrive belts require a break-in period ofapproximately 25 miles. Drive the snow-mobile for 25 miles at 3/4 throttle or less.By revving the engine up and down (butnot exceeding 60 mph), the exposed cordon the side of a new belt will be worndown. This will allow the drive belt togain its optimum flexibility and willextend drive belt life.

NOTE: Before starting the snowmo-bile in extremely cold temperatures,the drive belt should be removed andwarmed up to room temperature.Once the drive belt is at room temper-ature, install the drive belt (see DriveBelt sub-section in the Maintenancesection).

Cold Drive-Away Function (Z1/Z1 Turbo Models)On these models, there is a “cold drive-away” function incorporated within theengine.

NOTE: On models with a StandardGauge when cold-starting theengine, the coolant temperaturewarning icon will illuminate and thereadout screen will display TEMP.With the engine in this temperaturerange, the RPM “limit” of the enginewill be below drive system engage-ment speed. As the engine warms,the TEMP display will go out, thecoolant temperature warning iconwill begin to flash, and the RPM“limit” of the engine will increaseallowing the snowmobile to movewithout full-throttle operation. Whenthe engine reaches proper operatingtemperature, the coolant tempera-ture warning icon will go out.

CAUTIONDO NOT exceed the one (1) tankfullimitation of a 100:1 gas/oil break-inmixture. Continuous use of a gas/oilmixture, unless consistently operat-ing in extremely cold conditions (-26°C/-15°F or colder), could causespark plug fouling and excessivecarbon buildup. A 100:1 gas/oil mix-ture must be used in conjunctionwith the oil-injection system toensure adequate engine lubricationin extremely cold conditions.

CAUTIONDO NOT use premixed fuel in thesnowmobile gas tank. Engine dam-age will occur.

0-200 miles 1/2 Throttle (45 MPH-max)

200-400 miles 1/2-3/4 Throttle

400-600 miles 1/2-3/4 Throttle *

CAUTIONNever run the engine with the drivebelt removed. Excessive revving ofthe engine could result in seriousengine damage and drive clutch fail-ure.

NOTE: On models with a DeluxeGauge when cold-starting theengine, the coolant temperaturewarning icon will illuminate and theTEMP display on the readout screenwill begin to flash. With the engine inthis temperature range, the RPM“limit” of the engine will be belowdrive system engagement speed. Asthe engine warms, the coolant tem-perature warning icon will begin toflash, the TEMP display will continueto flash, and the RPM “limit” of theengine will increase allowing thesnowmobile to move without full-throttle operation. When the enginereaches proper operating tempera-ture, the coolant temperature warn-ing icon and the TEMP display willgo out.

If the Charging System Warning Iconilluminates, you should, as soon as possi-ble, take the snowmobile to an authorizedArctic Cat Snowmobile dealer for ser-vice. If not under warranty, this service isat the discretion and expense of thesnowmobile owner. The engine WILLNOT RUN without battery power.

Low Oil Warning Icon (F5/F6/F8 Models)

The Low Oil Warning Icon is designed toalert the snowmobile operator when theoil in the oil injection reservoir gets belowa prescribed level; however, it is highlyrecommended that a visual verification ofthe oil level in the reservoir be done priorto operating the snowmobile. Once theLow Oil Warning Icon illuminates duringoperation of the snowmobile, the operatormust periodically monitor the level of oilin the reservoir and must fill the reservoirthe next time gasoline is added to the gastank. The “alert level” of the Low OilWarning Icon is approximately equal to 1tankful of gasoline under normal operat-ing conditions.

Oil Pressure Warning Icon (Z1/Z1 Turbo Models)

The Oil Pressure Warning Icon indicatesengine oil pressure, not the oil level;however, if the oil level is low, it mayaffect oil pressure.

The icon should illuminate each time theignition switch is turned to RUN orSTART, and it should go out when theengine starts. If the icon illuminateswhile the engine is running, oil pressurehas been lost and the engine will auto-matically shut off.

If oil pressure is lost, use the followingprocedure to check the oil level:

1. With the engine off, remove theengine oil level stick and wipe itclean. Without screwing it in, set thestick back in the oil tank. Remove itand observe the oil level on thestick. If the oil level is at or belowthe ADD mark on the oil level stick,add only enough recommended oilto raise the level to the NORMALrange. DO NOT overfill the reser-voir with oil.

2. Open the air bleed bolt located onthe oil pump (beneath the coolanttank) to purge air from the oil hose.

ZJ004A

NOTE: When air can no longer beheard purging from oil pump bleed,tighten the bleed bolt to 7.5 ft-lb.

3. Start the engine. The warning iconshould go out within five seconds.

4. If the warning icon does not go out,shut the engine off immediately andrepeat step 2; then repeat step 3.

If the warning icon does not go out or ifthe engine does not start, take the snow-mobile to an authorized Arctic Cat Snow-mobile dealer. If not under warranty, thisservice is at the discretion and expense ofthe snowmobile owner.

Low Oil Warning Icon (CFR/F5/F6/F8 Models)

The Low Oil Warning Icon is designed toalert the snowmobile operator when theoil in the oil injection reservoir gets belowa prescribed level; however, it is highlyrecommended that a visual verification ofthe oil level in the reservoir be done priorto operating the snowmobile. Once theLow Oil Warning Icon illuminates duringoperation of the snowmobile, the operatormust periodically monitor the level of oilin the reservoir and must fill the reservoirthe next time gasoline is added to the gastank. The “alert level” of the Low OilWarning Icon is approximately equal to 1tankful of gasoline under normal operat-ing conditions.

Oil Pressure Warning Icon (Z1/Z1 Turbo Models)

The Oil Pressure Warning Icon indicatesengine oil pressure, not the oil level;however, if the oil level is low, it mayaffect oil pressure.

The icon should illuminate each time theignition switch is turned to RUN orSTART, and it should go out when theengine starts. If the icon illuminateswhile the engine is running, oil pressurehas been lost and the engine will auto-matically shut off.

If oil pressure is lost, use the followingprocedure to check the oil level:

1. With the engine off, remove theengine oil level stick and wipe itclean. Without screwing it in, set thestick back in the oil tank. Remove itand observe the oil level on thestick. If the oil level is at or belowthe ADD mark on the oil level stick,add only enough recommended oilto raise the level to the NORMALrange. DO NOT overfill the reser-voir with oil.

Cooling System (CFR/F5/F6/F8/Z1/Z1 Turbo Models)These snowmobiles are equipped with aclosed liquid cooling system for enginecooling. The cooling system should beinspected daily for leakage and damage.Also, the coolant level should be checkeddaily. If leakage or damage is detected,take the snowmobile to an authorizedArctic Cat Snowmobile dealer for ser-vice. If not under warranty, this service isat the discretion and expense of thesnowmobile owner.

When filling the cooling system reser-voir, use an ethylene glycol-based cool-ant/water mixture which will satisfy thecoldest anticipated weather conditions ofyour area in accordance with the coolantmanufacturer’s recommendations.

For checking/filling cooling system, referto Coolant Level sub-section in the Main-tenance section.

Battery (Electric Start)It is extremely important that the batterybe maintained at full charge at all timesand that the battery connections be cleanand tight. If charging the battery becomesnecessary, refer to Battery sub-section inthe Maintenance section.

Jump-Starting (Z1/Z1 Turbo Models)

NOTE: Arctic Cat does not recom-mend jump-starting a snowmobilewith a dead battery but rather toremove the battery, service it, andcorrectly charge it; however, in anemergency, it may be necessary tojump-start a snowmobile. If so, usethe following procedure to carefullyand safely complete this procedure.

1. On the snowmobile to be jump-started,slide any terminal boots away.

2. Inspect the battery for any signs ofelectrolyte leaks, loose terminals, orbulging sides. Leaking or bulgingbattery cases may indicate a frozenor shorted battery.

3. Inspect the vehicle to be used forjump-starting to determine if voltageand ground polarity are compatible.The vehicle must have a 12-volt DC,negative ground electrical system.

CAUTIONOn the Z1/Z1 Turbo models, alwaysturn the ignition switch key to theOFF position when the snowmobileis not being used. Leaving the igni-tion switch in the ON position willresult in discharging the battery andpossible damage to the battery.

! WARNINGImproper handling or connecting ofa battery may result in severe injuryincluding acid burns, electricalburns, or blindness as a result of anexplosion. Always remove rings andwatches.

! WARNINGAny time service is performed on abattery, the following must beobserved: keep sparks, open flame,cigarettes, or any other flame away.Always wear safety glasses. Protectskin and clothing when handling abattery. When servicing a battery inan enclosed space, keep the areawell-ventilated.

! WARNINGIf any of these conditions exist, DONOT attempt to jump-start, boost, orcharge the battery. An explosioncould occur causing serious injury.

When operating the snowmobile at highaltitudes, it may be necessary to changecertain component parts of the driveclutch and/or the driven pulley. See anauthorized Arctic Cat Snowmobile dealerfor further information.

Drive Clutch/Driven Pulley AlignmentThe parallelism and the offset betweenthe drive clutch and driven pulley are setat the factory. Normally, no adjustment isnecessary as long as neither the driveclutch nor the driven pulley is removedor disassembled. However, if prematuredrive belt wear is experienced or if thedrive belt turns over, the drive clutch/driven pulley alignment must bechecked. Take the snowmobile to anauthorized Arctic Cat Snowmobile dealerfor this service. If not under warranty,this service is at the discretion andexpense of the snowmobile owner.

Fuel PumpThe fuel pump is designed to provideadequate amount of gas to the carburetors(on the F570 model) or to the injectors(on the CFR/F5/F6/F8 models) at allthrottle settings. If a fuel delivery prob-lem is suspected, take the snowmobile toan authorized Arctic Cat Snowmobiledealer. If not under warranty, this serviceis at the discretion and expense of thesnowmobile owner.

Shock AbsorbersStandard Gas

Each shock absorber should be visiblychecked weekly for fluid leakage, cracksor breaks in the lower case, or a bentplunger. If any one of these conditions isdetected, replacement is necessary. Takethe snowmobile to an authorized ArcticCat Snowmobile dealer for this service.If not under warranty, this service is atthe discretion and expense of the snow-mobile owner.

NOTE: When the snowmobile isoperated in extremely cold weather(-23° C/-10° F or colder), a smallamount of leakage may be present.Unless the leakage is excessive,replacement is not necessary.

Rebuildable Gas

NOTE: The presence of a FOXidentifier (decal or embossed) on ashock absorber body indicates a“rebuildable” shock absorber.

NOTE: The frequency of servicingrebuildable shock absorbers will varyaccording to the types of conditionsand terrain the snowmobile has beensubjected to. If riding quality deterio-rates (or seems to be deteriorating),take the snowmobile to an authorizedArctic Cat Snowmobile dealer forshock absorber evaluation and/or ser-vicing. This service is at the discre-tion and expense of the snowmobileowner.

Standard-Lug TrackAccelerated wear strip wear caused byoperating on hard-packed snow condi-tions is NOT covered under Arctic CatInc. warranty policy.

Deep-Lug TrackSome models are equipped with a deep-lug track which is specially designed foruse in powder snow riding conditions.When the deep-lug track is operated inhard-packed snow conditions, it will runslightly slower than a standard-lug trackand it will accelerate wear strip wear. Todecrease the amount of wear strip wear,slower speeds must be maintained whenoperating on hard-packed trails. Acceler-ated wear strip wear caused by operatinga deep-lug track on hard-packed snowconditions is NOT covered under ArcticCat Inc. warranty policy.

NOTE: If operating on ice or hard-packed snow conditions, it is recom-mended that Ice Scratchers (p/n4639-958) be installed to reducewear strip and engine overheating.

Track Studs NOTE: Stud or hooker plate installa-tion will void track and tunnel warranty.

NOTE: Stud installation can be per-formed by the snowmobile owner ifqualified to do so. If the owner doesnot feel qualified, take the snowmo-bile to an authorized Arctic Cat Snow-mobile dealer for this service. Thisservice is at the discretion andexpense of the snowmobile owner.

NOTE: To prevent tunnel damagefrom the studs, Tunnel Protector Kit(p/n 4639-771) for the F570 model or(p/n 4639-968) for CFR models mustbe installed.

For proper installation, use the followingprocedure:

1. Using the stud template (see chart),mark the desired stud pattern to beused.

2. Using the proper-sized stud holedrill bit, drill out the stud holes.

3. Push the stud through the hole frominside the track; then place thedomed support plate and lock nut onthe exposed stud.

4. Using a wrench to secure the stud,tighten the lock nut on the exposed stud.

It is also recommended that wheneverstuds are installed on a track, carbidewear bars should be installed on the skis.Carbide wear bars complement the trackstuds to balance steering control underthese conditions. The length of the car-bide on the wear bars should be propor-tionate to the number of track studs (i.e.small number of track studs — shortlength of carbide...many track studs —long length of carbide). The proper pro-portion between the number of studs andcarbide length on the wear bar will main-tain steering balance.

! WARNINGWhen installing studs on a single-plytrack, it is important to use ArcticCat-approved studs (proper headdiameter). If approved studs (properhead diameter) are not used, studscould tear free of the track causingpossible injury or even death. Con-sult an authorized Arctic Cat Snow-mobile dealer for information.

CAUTIONIf installing studs on the CFR mod-els, a short Snowflap (p/n 5639-232)must be installed or component dam-age will occur.

Reverse OperationCFR/F570/F8 Models

The engine reverse function offers theoperator the convenience of being able toback up the snowmobile rather than hav-ing to turn the snowmobile around byhand. This feature, under most situations,should not be used to free a stuck snow-mobile as it will tend to dig the skisdeeper into the snow. Always use mini-mal speed when operating in reverse andcome to a complete stop before shiftingfrom either forward to reverse or reverseto forward.

Shifting Into Reverse

741-438A

NOTE: Correct drive belt tension(deflection) is important for thereverse function to operate properly.If the belt is too tight, difficulty inengaging reverse will be experi-enced (the reverse function willmake up to three attempts to engageinto reverse, and if the function isnot completed after the thirdattempt, the engine will shut down).

1. Always warm up the engine for 2-3minutes prior to shifting intoreverse. The reverse function is can-celled when engine temperature isbelow -22° F (-30° C) or above 176°F (80° C).

2. Shift only with the engine at idleRPM and the snowmobile com-pletely stopped. The reverse func-tion will not engage if engine speedis above 4000 RPM.

NOTE: If attempting to shift intoreverse at too high engine RPM(above 4000 RPM), the reverse func-tion will be cancelled and the coolanttemperature warning icon will flash.This indicates the reverse switchbutton was pressed at too high RPM.The operator must reduce engineRPM below 4000 and press the but-ton a second time.

3. Upon pressing the reverse switchbutton, the reverse function willmake up to three attempts to engageinto reverse. If the function is notcompleted after the third attempt,the engine will shut down.

Operating in Reverse

1. When reverse is engaged, a reverseicon will illuminate in the speedom-eter/tachometer and a reverse alarmwill sound.

2. If the throttle lever is compressedbefore complete reverse engage-ment, the engine may shut down.Always wait for the reverse icon toilluminate and the reverse alarm tosound before backing up.

CAUTIONDo not use studs that are more than9.525 mm (0.375 in.) longer than thetrack lug height.

! WARNINGDo not operate a snowmobile withloose studs as they may be thrownfrom the track. Always use a shieldedsafety stand whenever performingany maintenance or adjustments.

! WARNINGDO NOT stand behind the snowmo-bile or near the rotating track.NEVER run the track at high speedwhen the track is suspended.

CAUTIONNever shift into reverse while thesnowmobile is moving forward as itis hard on the driven pulley torquebracket and the cam rollers.

CAUTIONNever engage the electric starter orpull the recoil starter rope when theengine is running or when operatingin reverse. Damage to the engine and/or either the electric start or recoilstart system will occur.

21

3. On the CFR/F8 models if reverse isused for longer than five minutes con-tinuously, the engine will shut down.

NOTE: On the F570 model, the sys-tem will not shift until the button isreleased. Also, the reverse functionwill cancel if operated in reverse lon-ger than 45 seconds. Whenever thereverse function has been cancelled,the engine must be run in the for-ward mode for a minimum of 60 sec-onds at 2000 RPM before the reversefunction can be used again.

NOTE: While operating in reverse, a“rev-limiter” will activate at 6000 RPM.

4. After shifting from reverse to for-ward (or from forward to reverse),apply the throttle slowly and evenlyto allow the driven pulley to engageproperly.

5. The reverse function is cancelledwhenever the engine is shut off.

F5/F6/Z1/Z1 Turbo Models

The reverse transmission function offersthe operator the convenience of beingable to back up the snowmobile ratherthan having to turn the snowmobilearound by hand. This feature, under mostsituations, should not be used to free astuck snowmobile as it will tend to digthe skis deeper into the snow.

Always use minimal speed when operat-ing in reverse and come to a completestop before shifting from either forwardto reverse or reverse to forward.

1. Always warm up the engine for 2-3minutes prior to shifting intoreverse.

2. Come to a complete stop.

NOTE: The snowmobile must be ata complete stop and the engine run-ning under 3000 RPM (F5/F6 models)before the system will allow shifting.

3. With the engine at idle (under 3000RPM - F5/F6 models), press thereverse switch button; then releasethe button. The reverse selectionwill be complete.

NOTE: The system will not shiftuntil the button is released.

4. To shift into forward, stop the snow-mobile and all the engine to idle(under 3000 RPM - F5/F6 models);then press the button and release.The forward selection will be com-plete.

NOTE: An alarm will sound whenthe snowmobile is operated inreverse.

At high RPM, the exhaust valves areraised. This creates a “high port” exhaustdesign calibrated to provide maximumperformance at high RPM.

739-152H

NOTE: The RPM ranges will varyfrom model to model.

NOTE: If the servomotor cyclesthree times and then shuts down, theexhaust valve cables are notadjusted correctly. The exhaustvalves may also be sticking.

NOTE: APV cleaning may be doneby the snowmobile owner if qualifiedto do so. If the owner does not feelqualified, take the snowmobile to anauthorized Arctic Cat Snowmobiledealer for this service. This serviceis at the discretion and expense ofthe snowmobile owner.

Exhaust Controlled Timing (ECT) System (CFR/F6/F8 Models)This system automatically adjusts theignition timing to provide maximum per-formance through a variety of operatingconditions. The ECU receives input onengine RPM (demand) and exhaust pipetemperature (engine condition) andadjusts the ignition timing accordingly.This system is not adjustable and is main-tenance free.

If a system fault is suspected, use an ohm-meter to check continuity of the exhaustpipe temperature sensor located in theexpansion chamber. A reading of either 0ohm or infinity indicates a failed sensor.

0737-314

NOTE: A disabled ECT systemWILL NOT cause engine damage;however, a failed ECT system willhave slower throttle response andmay produce slightly less top-endperformance.

Operating InstructionsStarting and Stopping EngineIt is imperative that the brake system bechecked for wear and proper operation andthat all safety checks found in the accom-panying Snowmobile Safety Handbook beperformed before attempting to start theengine. Also, on the F570 model, be surethe correct carburetor main jets for theoperating temperature, altitude, andgasoline are being used. After the enginehas been started, check the headlights(high and low beam), taillight, and brake-light to be sure they are working properlyand adjusted correctly. Make sure all lightsare clean to provide maximum illumina-tion. The headlight and taillight must beclean and must be illuminated wheneverthe engine is running.

1. Test the operation of the brake sys-tem by compressing the brake lever.The brake lever must feel firm whencompressed; then while holding thebrake lever in the compressed posi-tion, measure the distance betweenthe brake lever and the handlebar.The distance must be greater than2.54 cm (1 in.).

741-328C

2. Check the fluid level in the reservoir.The brake fluid level must be visiblein the sight glass. Add Arctic Catapproved brake fluid as necessary.

741-328A

NOTE: If the sight glass appearsdark, there is a sufficient amount offluid in the reservoir.

3. Test the throttle control lever bycompletely compressing and releas-ing it several times. The leverMUST return to the idle positionquickly and completely.

4. Move the emergency stop switch tothe UP or RUN position.

5. Insert key into ignition switch; thenrotate key to the RUN position.

6. On the F570 model for a cold engine,move the choke lever to the full-choke position. If the engine is warm,choking is normally not necessary.

! WARNINGDo not start the engine if the brakesystem is not functioning properly.Service the brake system or have itproperly repaired prior to operating thesnowmobile. Serious personal injuryor even death may occur if the brakesystem is not operating properly.

CAUTIONOn the liquid cooled models, alwayscheck the coolant level before start-ing the engine.

25

0725-001

NOTE: On the F570 model whenthe engine is being started with aidof the choke, DO NOT COMPRESSTHE THROTTLE CONTROL LEVER. Ifthe throttle control lever is com-pressed, the engine will not startbecause the gas/air mixture will betoo lean. To start a warm engine,however, the throttle control levermay have to be compressed slightly.

NOTE: On the CFR/F5/F6/F8 mod-els when a cold engine is beingstarted, DO NOT COMPRESS THETHROTTLE CONTROL LEVER. If thethrottle control lever is compressed,the engine will not start because thefuel/air mixture will be too lean.

NOTE: On the CFR/F5/F6/F8 mod-els when a warm engine is beingstarted, the throttle control lever mayhave to be compressed slightly.

7. On models with manual start, pullthe recoil handle slowly until resis-tance is felt; then give a short quickpull. Repeat until the engine starts.

NOTE: On large-diasplacementengines in extremely cold weather, pullthe recoil handle slowly two to threetimes to begin the starting procedure.

NOTE: On electric start models,rotate the key to the START position;then when the engine starts, releasethe key.

8. On the F570 model when the enginestarts, allow it to warm up forapproximately 30 seconds with thechoke lever in the full-choke posi-tion. After the 30-second warm-up,move the choke lever to the middleposition. The choke lever should bemoved to the OFF position whenengine is warm. Slight throttle con-trol lever compression may be nec-essary after the engine starts andduring warm-up. Idle the engineseveral minutes until the engine hasreached normal operating tempera-ture.

NOTE: On the CFR/F5/F6/F8 mod-els when the engine starts, allow it towarm up properly. Idle the engineseveral minutes until the engine hasreached normal operating tempera-ture. Do not idle the engine forexcessively long periods of time.

9. On the Z1/Z1 Turbo models, there isa “cold drive-away” function incor-porated within the engine. This func-tion is active until the engine reachesoperating temperature (see ColdDrive-Away Function sub-section inthe General Information section).

CAUTIONTo avoid damaging the recoil starter,DO NOT pull the recoil rope to itslimit or release the recoil handlefrom an extended position. Allow therope to rewind slowly.

CAUTIONDo not continuously run the starterfor more than 5 seconds at a time.

CAUTIONIt is extremely important that theengine is properly warmed up beforesubjecting the engine to high speedoperation or heavy loads. Theengine should be allowed to idle atleast 3-4 minutes before it is oper-ated at more than 1/2 throttle. Inextremely cold conditions, thewarm-up time will be longer. Coldseizure and piston scuffing causedby insufficient warm-up will not becovered by warranty. Also, do notidle the engine for excessively longperiods of time.

26

10. Flooding — On the F570 model ifthe engine does not start when thechoke is being used but seems readyto start, move the choke lever to theOFF position. Engage the brakelever lock; then compress the throt-tle control lever fully and try to startthe engine. When the engine starts,release the throttle control leverimmediately. After the warm-up,release the brake lever lock.

NOTE: Continued choking willcause the engine to flood more.

NOTE: On the F570 models if theengine fails to start during theattempt with the throttle control levercompressed, remove the spark plugsand clean and dry them thoroughly orinstall a new set of properly gapped,recommended spark plugs.

11. Flooding — On the CFR/F5/F6/F8/Z1/Z1 Turbo models if the enginedoes not start but seems ready tostart, engage the brake lever lock;then compress the throttle controllever fully and try to start the engine.When the engine starts, release thethrottle control lever immediately.After the warm-up, release the brakelever lock.

NOTE: On the CFR/F5/F6/F8 mod-els if the engine fails to start duringthe attempt with the throttle controllever compressed, remove the sparkplugs and clean and dry them thor-oughly or install a new set of properlygapped, recommended spark plugs.

NOTE: On the Z1/Z1 Turbo modelsif spark plugs must be replaced, takethe snowmobile to an authorizedArctic Cat Snowmobile dealer forinspection and service. This serviceis at the discretion and expense ofthe snowmobile owner.

12. To shut off the engine, turn the igni-tion key to the OFF position or pushthe emergency stop switch to theDOWN position.

BrakingThe following items are items that theoperator must be familiar with whenoperating this snowmobile and itshydraulic brake system. Important addi-tional information on the proper mainte-nance of the brake system is found in theMaintenance section.

1. Use the brakes wisely. Each time thebrakes are applied in all hydraulicbrake systems (including automotiveapplications), heat is transferred tothe brake fluid. The amount of heattransferred during high speed stopsand/or repetitive use may be highenough to boil the brake fluid andcause the brakes to either fade or maycause an unexpected loss of brakes.

If this occurs, the brake fluid requiresa cool-down period before the brakeswill again function properly. Thiscool-down period will vary depend-ing upon the ambient air temperatureand the temperature of the brakefluid. If loss of brakes has occurredbecause of high fluid temperatures,do not operate the snowmobile untilthe cool-down period has expired andbrake lever firmness has returned.

CAUTIONOn the Z1/Z1 Turbo models, alwaysturn the ignition switch key to theOFF position when the snowmobileis not being used. Leaving the igni-tion switch in the ON position willresult in discharging the battery andpossible damage to the battery.

! WARNINGExcessive repetitive use of thehydraulic brake for high speed stopswill cause overheating of the brakefluid and premature brake pad wearwhich will result in an unexpectedloss of brakes.

27

2. Be sure to maintain the brake fluid atthe proper level and take care not toget any moisture in the system asmoisture in the brake fluid lowers theboiling point. If the brake fluid is everboiled (by high speed stops or repeti-tive use) or if moisture is allowed toenter the system, it must be changed.Never substitute or mix different typesor grades of brake fluid.

3. Never ride the brake. Even main-taining minimal pressure on thebrake lever will cause the brake padsto drag on the disc and may overheatthe brake fluid.

4. The brake lever lock is not a parkingbrake and should not be applied forperiods exceeding 5 minutes.NEVER OPERATE THE SNOW-MOBILE WITH THE BRAKELEVER LOCK ENGAGED.

5. Pumping the brake lever is permissi-ble; however, if pumping the brakelever more than twice is necessary toobtain the necessary stopping power,immediately take the snowmobile toan authorized Arctic Cat Snowmo-bile dealer for service. If not underwarranty, this service is at the discre-tion and expense of the snowmobileowner.

6. When new brake pads are installed, a“burnishing” process is required. Drivethe snowmobile slowly and compressthe brake lever several times until thepads just start to heat up; then allowthem to thoroughly cool down. Thisprocess stabilizes the pad material andextends the life of the pads.

Emergency StoppingThere are several methods of stopping orslowing the snowmobile under a varietyof situations. Identified in the followingchart are the ways a snowmobile may bebrought to a stop and the effectivenessunder normal conditions.

Throttle/Ignition Monitor SwitchThe throttle control is equipped with amonitor switch for safety purposes whichwill stop the engine when a loss of returnspring force occurs. If ice forms in thethrottle system or if there is some othermalfunction of the throttle system result-ing in a loss of return spring force, themonitor switch will stop the engine whenthe throttle control lever is released.

If the snowmobile engine stops abruptlywhen the throttle control lever is releasedand the activation of the monitor switch issuspected, use the following procedure:

! WARNINGUse only Arctic Cat approved brakefluid. Never substitute or mix differ-ent types or grades of brake fluid.Brake loss can result. Check brakefluid level and pad wear before eachuse. Brake loss can result in severeinjury or even death.

! WARNINGThe brake lever lock is not a parkingbrake and should not be applied forperiods exceeding 5 minutes. Thebrake lever lock maintains the brakelever in the compressed position andmaintains pressure against thebrake disc; however, after a period oftime, the pressure applied to thebrake disc may relax below theamount required to hold the snow-mobile stationary.

3. Test the throttle control lever bycompressing and releasing it severaltimes. The lever MUST return to theidle position quickly and completely.

NOTE: If the throttle control leveroperates properly and the enginedoes not start, compress the throttlelever slightly (approximately 1/8throttle) and try starting the engine.If the engine now starts and stopswhen the throttle lever is released,take the snowmobile to an autho-rized Arctic Cat Snowmobile dealerfor service. If not under warranty,this service is at the discretion andexpense of the snowmobile owner.

4. If the throttle control lever operatesproperly, rotate the ignition key tothe RUN position and go throughnormal starting procedures.

NOTE: On the F570 model if thethrottle control lever operates prop-erly and the engine does not start,either a malfunctioning monitorswitch or a misadjusted magneticcarburetor switch may be the prob-lem. Take the snowmobile to anauthorized Arctic Cat Snowmobiledealer for service. If not under war-ranty, this service is at the discretionand expense of the snowmobileowner. However, if a dire emergencyexists wherein the engine must bestarted, disconnect the carburetorsafety switch connectors.

29

NOTE: The monitor switch is nowbypassed. All other ignition/electricalfeatures (ignition switch, emergencystop switch, headlight, taillight, andbrakelight) will operate properly.

Varying Altitude OperationOperating a snowmobile at varying alti-tudes requires changes in performancecomponents. These changes affect drivetrain components (on certain models) andcarburetion components (F570 models).

The altitude information decal is locatedon the belt guard of the snowmobile (F-Series models) or beneath the hood of thesnowmobile (CFR models). On the F570model, the information is incorporatedinto the Carburetor Jet Chart decal on thebelt guard.

NOTE: Just as important as cali-brating the snowmobile for higheraltitudes is recalibrating the snow-mobile when going to lower alti-tudes.

NOTE: Carburetion and drive trainchanges can be made by the snow-mobile owner if qualified to do so. Ifthe owner does not feel qualified,take the snowmobile to an autho-rized Arctic Cat Snowmobile dealerfor this service. This service is at thediscretion and expense of the snow-mobile owner.

! WARNINGUnder no circumstances should dis-connection of the throttle control wir-ing harness be used as a substitutefor the monitor switch during normaloperation of the snowmobile. Per-sonal injury and damage could occurif the throttle system malfunctions orif the operator is unable to stop theengine in an emergency. If the snow-mobile must be operated with a dis-connected throttle control wiringharness, EXTREME CAUTION MUSTBE TAKEN. NEVER EXCEED 10 MPHWITH THE THROTTLE CONTROLWIRING HARNESS DISCONNECTED.

CAUTIONOn the F570 model, carefully followthe Carburetor Jet Chart recommen-dations for proper altitude calibra-tion.

The longevity and safety of the snowmo-bile can be increased by making periodicchecks of the items in the precedingchecklist.

If, at any time, abnormal noises, vibra-tions, or improper working conditions ofany component of this snowmobile aredetected, DO NOT OPERATE THESNOWMOBILE. Take the snowmobileto an authorized Arctic Cat Snowmobiledealer for inspection and adjustment orrepair. If not under warranty, this serviceis at the discretion and expense of thesnowmobile owner.

The snowmobile should be taken to anauthorized Arctic Cat Snowmobile dealerat the end of each snowmobiling seasonfor general inspection and for off-seasonstorage servicing. This inspection andservicing is at the expense of the snow-mobile owner.

Air Cleaner/Filter (Z1 Turbo Models)The air filter inside the air cleaner hous-ing must be kept clean to provide goodengine power and gas mileage. If thesnowmobile is used under normal condi-tions, inspect the filter weekly andreplace the filter at the intervals speci-fied. If operated in adverse conditions,inspect and service the filter more fre-quently. Use the following procedure toremove the filter and to inspect and/orreplace it.

1. Remove the air cleaner cover; thenremove the air filter.

2. Inspect the air filter for dirt or dam-age.

3. Clean any debris from inside the airintake plenum.

4. Place the new filter (if necessary)into the plenum; then secure the aircleaner cover onto the plenum.

Fuel System

In-Line Fuel Filter (F570 Model)

Arctic Cat recommends that the in-linefuel filter be checked weekly. The in-linefuel filter is located just in front of thefuel pump inlet fitting. The filter must beclean to allow the fuel hose to transmitthe amount of gasoline required.

If the in-line fuel filter is obstructed, gas-oline flow will be restricted; therefore,the filter must be replaced. To removeand install the in-line fuel filter, use thefollowing procedure:

1. Pinch off the fuel hose between thegas tank and fuel filter.

2. Remove and discard the clamps;then pry the fuel hoses off the in-linefuel filter and remove the filter.

NOTE: The in-line fuel filter mustbe replaced if obstructed. Filters areavailable from an authorized ArcticCat Snowmobile dealer.

CAUTIONFailure to inspect the air filter fre-quently if the snowmobile is used inadverse conditions can damage theturbocharger/engine.

CAUTIONDo not use compressed air in anattempt to clean the filter. Damage tothe filter may occur. If the filter isdirty, it must be replaced.

CAUTIONA torn air filter can cause damage tothe turbocharger/engine. Contami-nants may get inside the turbo-charger/engine if the filter is torn.Carefully examine the filter for holesor tears. Replace the filter with a newone if it is torn.

CAUTIONDo not run the engine without the airfilter installed. Severe damage to theturbocharger/engine will occur.

! WARNINGWhenever any maintenance orinspection is made on the fuel sys-tem in which there may be fuel leak-age, there should be no welding,smoking, open flames, etc., in thearea.

36

3. Install the new in-line fuel filter (ifnecessary) in the fuel hose so thearrow on the filter points toward thefuel pump. Make sure the fuel hosesfit tightly on the filter. If the existingfuel hose does not fit tightly on thefilter, cut 6 mm (1/4 in.) from the endof the fuel hose; then install on thefilter and secure with new clamps.

728-272B

In-Line Fuel Filter (Z1/Z1 Turbo Models)

Arctic Cat recommends that the in-linefuel filter be replaced every 5000 miles.The in-line fuel filter is located justinside the left-side access panel. The fil-ter must be clean to allow the fuel hose totransmit the amount of gasoline required.

If the in-line fuel filter is obstructed, gas-oline flow will be restricted; therefore,the filter must be replaced. To removeand install the in-line fuel filter, use thefollowing procedure:

NOTE: Before removing the fuel fil-ter, take note of the filter inlet andoutlet for installing purposes.

1. Open the left-side access panel; thenremove the fuel filter from the bracket.

NOTE: On the Z1 Turbo models toaccess the fuel filter, remove thescrew (A) securing the left-side rearspar to the gas tank; then removethe screws (B) securing the left-sideknee pad.

744-463A

2. Remove the hose clamps and discard;then slowly remove the fuel hosesfrom the fuel filter. Dispose of theexcess fuel from the filter properly.

3. Inspect the fuel hoses thoroughly forany signs of cracking, cuts, or wearpoints.

4. Place the new hose clamps on thefuel hoses; then with the fuel pumpinlet and outlet noted, connect thefuel hoses to the fuel filter. Securewith the hose clamps.

5. Secure the new fuel filter to the fuelfilter bracket; then start the engineand inspect the fuel hoses and filterfor any signs of leaks.

Gasoline Additives

Fuel de-icer can be used for all models.Also, periodic use of an injector cleanerfor CFR/F5/F6/F8/Z1/Z1 Turbo modelsis recommended especially in the lasttank of gasoline before storage. ArcticCat Fuel Stabilizer (p/n 0436-907) shouldalso be added to the last tank of gasolinebefore storage.

! WARNINGThe fuel hoses must fit tightly on thefuel filter. If the fuel hose lengthdoesn’t permit this procedure, replacethe fuel hose. Also, after installing thefuel hoses on the filter, check to besure that the fuel hoses do not contactany hot or rotating components.

! WARNINGSince the fuel supply hose may beunder pressure, always wear safetyglasses; then remove the hoseslowly to release the pressure. Placean absorbent towel around the con-nection to absorb the fuel.

37

Fuel Pickup Valves

Checking Spark Plugs

To see if the spark plugs being used are ofthe proper heat range (after the snowmo-bile has been operated under normal driv-ing conditions), remove the spark plugsand examine the condition of the centerelectrode insulator of each spark plug.

AO352A

A. TAN or LIGHT BROWN insula-tor indicates correct spark plugs(heat range).

B. LIGHT GRAY or WHITE insula-tor indicates over-heating of theengine. This condition is caused bya too lean condition or incorrectspark plugs (heat range too hot).

C. BLACK insulator indicates fuelin the combustion chamber is notburning completely. This condi-tion is caused by a too rich con-dition, too much oil, or incorrectspark plugs (heat range too cold).

44

NOTE: If the center electrode insu-lators are light gray, white, or blackand if the carburetor adjustments(F570 model),oil-injection pump syn-chronization, and ignition timing arecorrect, different heat-range sparkplugs may be necessary. AuthorizedArctic Cat Snowmobile dealers havedetailed spark plug information. Con-sult a dealer before changing sparkplugs, as incorrect heat-range sparkplugs could cause poor engine per-formance or engine damage.

NOTE: The brake pads may bechanged by the snowmobile owner ifqualified to do so. If the owner doesnot feel qualified, take the snowmo-bile to an authorized Arctic CatSnowmobile dealer for this service.This service is at the discretion andexpense of the snowmobile owner.

NOTE: When installing new brakepads, always install them as a set.Never install just one pad or usebrake pads which have been used inanother snowmobile.

1. Measure the thickness of both brakepads. The brake pad thickness mustbe greater than 5.0 mm (0.20 in.). Ifthe brake pad thickness is less thanspecified, replacement of both padsis necessary.

0739-269

2. Remove the pin/hairpin clip secur-ing the brake pads to the caliperassembly.

3. Remove the brake fluid reservoircover; then remove most of thebrake fluid from the reservoir. Installthe cover.

NOTE: The above procedure willallow room for the fluid from the cali-per when the pistons are pushedinto the caliper for installing newbrake pads. Replacing the cover willprevent fluid spillage.

4. Using a pair of pliers, pull one brakepad out of the caliper assembly.

NOTE: Changing one pad at a timewill prevent one piston from pushingout the other piston from the caliper.

5. Using a flat-blade tool, slowly and care-fully push the piston into the caliper.

6. Position the new brake pads into thecaliper.

7. Repeat steps 4-6 for the other pad;then secure the pads with the pin/hairpin clip.

8. Remove the reservoir cover andremove the remaining fluid; then fillthe reservoir with fresh fluid andinstall the cover.

9. Pump the brake lever to ensure cor-rect positioning of the brake pads;then release.

10. Remove the reservoir cover and fillthe reservoir to the proper level withfresh brake fluid; then install thecover.

NOTE: When new brake pads areinstalled, a “burnishing” process isrequired. Drive the snowmobile slowlyand compress the brake lever severaltimes until the pads just start to warmup; then allow them to cool down. Thisprocedure stabilizes the pad materialand extends the life of the pads.

Drive BeltThe drive belt transfers power from thedrive clutch to the driven pulley. If thebelt is worn, cracked, or stretched, maxi-mum power will not be transmitted andthe belt could also fail and therefore mustbe replaced. Periodic checks (at leastonce a month under normal usage) of twodrive belt specifications are essential.

1. Measure the outside circumferenceof the drive belt. The belt should bewithin the recommended range incircumference.

51

2. Measure the outside width of thedrive belt. The belt should be withinthe recommended range in width.

3. Check the belt for cracking, fraying,etc.

If any of the specifications or conditionsare unsatisfactory, replace the drive belt.

NOTE: Drive belts should be pur-chased from an authorized ArcticCat Snowmobile dealer, as Arctic Catdrive belts are made to exact specifi-cations and of quality material. Beltsmade by other manufacturers maynot be of the same specifications orquality and, therefore, usage couldresult in poor performance and pre-mature belt failure.

NOTE: Before starting the snowmo-bile in extremely cold temperatures,the drive belt should be removed andwarmed up to room temperature.Once the drive belt is at room temper-ature, install the drive belt.

Also, new drive belts have a break-inperiod of approximately 25 miles. Afterinstalling a new drive belt, drive thesnowmobile for 25 miles at 3/4 throttle orless. By revving the engine up and down(but not exceeding 60 mph), the exposedcord on the side of a new belt will beworn down.This will allow the drive beltto gain its optimum flexibility and willextend drive belt life.

Checking/Adjusting Drive Belt Deflection

0743-319

The drive belt must have the proper fit inthe drive clutch and driven pulley. Tocheck for proper drive belt fit, use thefollowing procedure.

1. Place a straightedge on the top of thedrive belt. The straightedge shouldreach from the drive clutch to the topof the driven pulley.

NOTE: Make sure the drive belt isall the way out in the driven pulleybefore checking drive belt fit.

2. Using a stiff ruler centered betweenthe drive clutch and driven pulley,push down on the drive belt justenough to remove all slack and notethe amount of deflection. Thedeflection should be within therange of 28.5-31.8 mm (1 1/8-1 1/4in.).

3. To correct drive belt deflection,remove the sheave adjuster from thepulley, remove or add shim washersto the adjuster, and install theadjuster.

NOTE: Adding shim washers willdecrease belt deflection and remov-ing shim washers will increase beltdeflection. Available shim washersfrom Arctic Cat are p/n 0648-714(0.090 in.) - one included in the toolkit, p/n 0648-715 (0.030 in.), and p/n0648-716 (0.060 in.).

NOTE: Removing/adding shimwashers may be done by the snow-mobile owner if qualified to do so. Ifthe owner does not feel qualified,take the snowmobile to an autho-rized Arctic Cat Snowmobile dealerfor this service. This service is at thediscretion and expense of the snow-mobile owner.

5. Remove the cap screw (w/lockwasher and washer) from theadjuster, remove the washer andlock washer from the cap screw, turnthe adjuster around (reverse it), andinsert the cap screw into the adjuster.

0744-551

6. Install the sheave adjuster and capscrew onto the driven pulley; thentighten the cap screw until the mov-able sheave opens far enough toallow the belt to be removed.

NOTE: Before installing the drivebelt, use a suitable cleaning solventto thoroughly clean the sheaves.

7. Remove the drive belt from thedriven pulley first; then from thedrive clutch.

Installing Drive Belt

NOTE: If a new drive belt is beinginstalled, see Drive Belt Break-Insub-section in the General Infor-mation section.

1. Place the drive belt (so the part num-ber can be read) between the sheavesof the drive clutch first; then betweenthe sheaves of the driven pulley.

2. Remove the sheave adjuster and installit in its original position (beveled sideout); then install the cap screw, lockwasher, washer, and sheave adjusterback into the driven pulley. Tighten thecap screw to 32 ft-lb.

3. Install the belt guard; then close theleft-side access panel.

4. Release the brake lever lock.

Track TensionTrack tension is directly related to the over-all performance of the snowmobile. If thetrack is too loose, it may slap against thetunnel causing wear or it may “ratchet” onthe track drive sprockets. If extremelyloose, the idler wheels may climb over thetrack lugs forcing the track against the tun-nel causing the track to “lock.” Arctic Catrecommends that the track tension bechecked daily during the first 300 miles ofoperation and once a week thereafter andadjusted according to need. The track willstretch and take a “set” during break-in.Track deflection must be maintained withinthe recommended range.

CAUTIONDo not apply Loctite to the drivenpulley cap screw or componentdamage may occur.

! WARNINGNever operate the snowmobile with-out the belt guard/access panelsecured in place.

! WARNINGTrack tension must be properlymaintained. Personal injury couldresult if a track is allowed to becomeexcessively loose.

53

Checking Track Tension

1. Remove excess ice and snow buildupfrom the track, track drive sprockets,and the inside of the skid frame.

2. Elevate the snowmobile on ashielded safety stand high enough touse a spring scale.

3. At mid-point of the track (on thebottom side), hook a spring scalearound a track clip; then pull downon the scale to the recommendedpressure. Measure the deflection(distance) between the bottom of thewear strip and the inside surface ofthe track clip. Compare the measure-ment with the chart.

0743-188

Adjusting Track Tension

NOTE: To ensure proper track ten-sion adjustment, perform all adjust-ments on both sides of thesnowmobile.

1. Loosen the rear idler wheel adjust-ing bolt jam nuts.

739-636B

2. If the deflection (distance betweenthe bottom of the wear strip and theinside of the track) exceeds specifi-cations, tighten the adjusting bolts totake up excessive slack in the track.

3. If the distance between the bottom ofthe wear strip and the inside surfaceof the track is less than specified,loosen the adjusting bolts to increasethe slack in the track.

4. Check track alignment (see TrackAlignment sub-section in this sec-tion).

5. When proper track tension isobtained, tighten the adjusting boltjam nuts against the axle housings.

NOTE: Since track tension andtrack alignment are interrelated,always check both even if only oneadjustment seems necessary.

Track AlignmentProper track alignment is obtained whenthe rear idler wheels are equal distancefrom the inner track drive lugs. Excessivewear to the idler wheels, drive lugs, andtrack will occur if the track is improperlyaligned. Arctic Cat recommends that thetrack alignment be checked once a weekor whenever the track tension is adjusted.

! WARNINGDO NOT attempt to check or adjusttrack tension with engine running.Turn ignition key to the OFF position.Personal injury could result fromcontact with a rotating track.

! WARNINGIf jam nuts are not tightened prop-erly, the adjusting bolts could loosencausing the track to becomeextremely loose and, under someoperating conditions, allow the idlerwheels to climb over the track lugsforcing the track against the tunnelcausing the track to “lock.” If a track“locks” during operation, severe per-sonal injury could result.

54

Checking Track Alignment

1. Remove excess ice and snow buildupfrom the track, track drive sprockets,and the inside of the skid frame.

2. Position the tips of the skis against awall; then using a shielded safetystand, raise the rear of the snowmo-bile off the floor making sure thetrack is free to rotate.

3. Start the engine and accelerateslightly. Use only enough throttle toturn the track several revolutions.SHUT ENGINE OFF.

NOTE: Allow the track to coast to astop. DO NOT apply the brakebecause it could produce an inaccu-rate alignment condition.

4. When the track stops rotating, checkthe relationship of the rear idlerwheels and the inner track drive lugs.If the rear idler wheels are centeredbetween the inner track drive lugs, noadjustment is necessary.

725-070A

5. If the idler wheels are not centeredbetween the inner track drive lugs,an adjustment is necessary.

Adjusting Track Alignment

1. On the side of the track which has theinner track drive lugs closer to therear idler wheel, loosen the adjustingbolt jam nut; then rotate the adjustingbolt clockwise 1 to 1 1/2 turns.

739-636B

2. Check track alignment and continueadjustment until proper alignment isobtained.

NOTE: Make sure correct tracktension is maintained after adjust-ing track alignment (see Track Ten-sion sub-section in this section).

3. After proper track alignment isobtained, tighten the adjusting boltjam nut against the axle housing.

4. Field test the track under actual con-ditions.

5. After the field test, check the align-ment of the track. If additional adjust-ment is necessary, repeat AdjustingTrack Alignment procedure.

SuspensionThe suspension should be adjusted forthe operational needs and riding prefer-ence of the operator.

! WARNINGMake sure the ignition key is in theOFF position and the track is notrotating before checking or adjustingtrack alignment. Personal injurycould result if contact is made with arotating track.

! WARNINGThe tips of the skis must be posi-tioned against a wall or similar object.


! WARNINGIf a jam nut is not tightened properly,the adjusting bolt could loosen causingthe track to become dangerously loose.

55

The front shock springs determine theamount of ski pressure and the reactionof the front suspension to rough terrain.The amount of ski pressure can also bechanged by adjusting the length of theskid frame front arm limiter straps.

The rear springs influence the load carry-ing capability of the snowmobile andshould be adjusted for the weight and rid-ing preference of the operator.

Adjusting Front (Ski) Shock Springs (CFR/F8/Z1 Turbo/EXT Models)

NOTE: On the F5/F570/Z1 non-turbo models, the front (ski) shocksprings are not adjustable.

The front (ski) shock springs are individu-ally adjustable for the terrain conditionsand driving style of the operator. Thespring adjuster nut has been set at the fac-tory so the correct amount of threads areexposed between the adjuster nut and thethreaded shock body as an initial setting.Additional ski pressure can be obtained bytightening the spring tension; ski pressurecan be decreased by relaxing spring ten-sion.

NOTE: Equal adjustments shouldbe maintained on both sides of thesnowmobile.

Front (ski) shock spring pre-load adjust-ment is accomplished by loosening theadjuster nut locking collar (B) from theadjuster nut (A) and using the SpringAdjuster Tool from the tool kit, rotatingthe adjuster nut in whichever direction isdesired. Tighten the locking collaragainst the adjuster nut.

0745-159

Adjusting Fox Air Shocks (Sno Pro Models)

NOTE: It is recommended to moni-tor the air pressure in the air shocksonce every month.

NOTE: Adjusting air shocks maybe done by the snowmobile owner ifqualified to do so. If the owner doesnot feel qualified, take the snowmo-bile to an authorized Arctic CatSnowmobile dealer for this service.This service is at the discretion andexpense of the snowmobile owner.

The air shocks are individually adjustablefor the terrain conditions and driving styleof the operator. The shocks are preset atthe factory (see chart) as an initial setting;however, it is possible to “fine tune” theshocks to match the operator’s weight,riding style, and terrain conditions.

Checking and adjusting air pressure mustbe done at riding temperature (outside).Also, it is advisable to check air pressurewhen the outside temperature variesmore than 25°.

NOTE: Care should be taken to haveequal pressure in the front (ski) shocksbefore operating the snowmobile.

To increase or decrease air pressure, usethe following procedure.

NOTE: When adjusting air pres-sure, all weight must be removedfrom the suspension, and the shockabsorbers must be fully extended.

NOTE: Adding air pressure willincrease the air spring force; reduc-ing air pressure will decrease airspring force.

1. Remove the air valve cap from theshock.

! WARNINGDo not exceed 10.5 kg/cm2 (150 psi)in the shock.

56

2. Thread the valve of Shock AbsorberAir Pump (p/n 2603-614) onto theshock air valve approximately sixrotations.

NOTE: As the pump is being attachedto the shock, the hose will fill with air.This will result in a lower gauge pres-sure 0.14-3.52 kg/cm2 (2-5 psi).

3. To decrease air pressure in theshock, press the black bleed valvebutton half way down and hold untildesired pressure is attained.

NOTE: Pressing the button fullydown and releasing it will allow onlya small amount of air to escape(micro-adjust).

4. To increase air pressure in the shock,pump until desired pressure isattained.

5. Remove the pump valve from theshock air valve.

NOTE: As the pump valve is beingremoved from the shock, the soundof air loss is from the pump hose,not from the shock.

6. Install the air valve cap onto theshock.

Adjusting Skid Frame Front Arm

NOTE: On the F5/F570/Z1 non-turbo models, the front arm shockspring is not adjustable.

The skid frame front arm shock spring ten-sion and the limiter straps are adjustable.However, Arctic Cat recommends that theshock spring be maintained at the factorypreset of 1/8-1/4 in. preload. Tighteningthe skid frame front arm shock spring maycause improper balance and may ruin thehandling features of the snowmobile.

The length adjustment of the front armlimiter straps determines the weight dis-tribution between the front of the skidframe and the skis. Tightening the limiterstrap (shortening the strap) will pull upon the front of the skid frame and willincrease ski pressure. Loosening the lim-iter strap (lengthening the strap) lowersthe front of the skid frame and decreasesski pressure.

When customizing the amount of skipressure, be sure to adjust both strapsequally and do not over-adjust the limiterstraps to adversely affect steering andoperator control of the snowmobile.Some experimentation may be requireduntil the proper adjustment for the opera-tor’s individual style is obtained.

NOTE: If the limiter straps areadjusted, it is highly recommendedthat at least a minimum of 1/8 in. pre-load on the shock spring be main-tained.

Adjusting Rear Spring Pre-Load

Proper adjustment of rear spring pre-loadis necessary to get the most desirableride. The chart is designed to help in set-ting up rear spring pre-load; however,riding style is the single greatest factor indetermining rear spring requirements.

NOTE: These cam position set-tings are suggestions only. Personalriding style will greatly influencecam position settings. Spend time todetermine setting preferences.

Rear spring pre-load adjustment isaccomplished by rotating the adjustingcams. Position 3 provides the stiffestride, and position 1 is for the light driveror slow-speed trail riding. Position 2 isfor the average operator under normalconditions. Always rotate the cam fromthe lighter position to the heavier posi-tion.

! WARNINGDo not adjust the front arm limiterstraps to a point at which steeringand operator control of the snowmo-bile are adversely affected.

7. Adjust the headlight using theadjustment knobs until correct aim isobtained. Shut the engine off; thendisengage the brake lever lock.

Ski Wear BarsThe ski wear bar is a replaceable barattached to the underside of the ski. Thepurpose of the wear bar is to assist inturning the snowmobile, to minimize skiwear, and to maintain good steering con-trol. If the snowmobile is operated pri-marily in deep snow, ski wear bar wearwill be minimal; however, if the snow-mobile is operated on terrain where thesnow cover is minimal, the ski wear barwill wear faster. To maintain positivesteering characteristics, Arctic Cat rec-ommends that the ski wear bars bechecked before each use and replaced ifworn beyond 1/2 of the original diameter.Ski wear bars are available from anauthorized Arctic Cat Snowmobiledealer.

Removing Ski Wear Bars

NOTE: Determine which type ofwear bar is being replaced andremove and install accordingly.

1. Remove ice and snow buildup fromthe ski.

2. Using a suitable safety stand or lift,elevate the front of the snowmobile.

3. Remove the lock nuts securing thewear bar to the ski.

! WARNINGDo not operate the snowmobileunless headlight beam is adjustedproperly. An incorrectly adjustedbeam will not provide the operatorthe optimum amount of light.

! WARNINGOperating the snowmobile withexcessively worn ski wear bars mayresult in a loss of steering control.

0743-185

4. Remove the wear bar from the ski.

Installing Ski Wear Bars

1. Move the wear bar into position onthe bottom of the ski.

NOTE: If installing a double-offsetwear bar, the carbide edge must bedirected to the outside of the ski.

2. Align the wear bar studs with theholes in the ski; then install the locknuts. Tighten to 11-15 ft-lb.

Adjusting Ski Stance (CFR Models)NOTE: Local laws and/or regula-tions as to maximum width of the skistance on these snowmobiles maybe applicable. Always comply withthe maximum width laws and/or reg-ulations when adjusting ski stance.

NOTE: Ski stance can be increased/decreased by 2.5 cm (1.0 in.).

1. Place the front of the snowmobile ona support stand.

2. Remove the cotter pin; then removethe slotted nut and cap screw secur-ing the ski assembly to the spindle.Remove the ski. Account for therubber damper, inserts, and washers.

3. To increase ski stance, place both skistance spacers to the outside of thespindle.

4. To decrease ski stance, place bothski stance spacers to the inside of thespindle.

5. Apply an all-temperature grease to thenon-threaded portion of the capscrew; then slide the cap screwthrough the ski accounting for the rub-ber damper, inserts, and washers.

NOTE: Install the cap screw so theslotted nut will be located to theinside of the ski.

6. Apply red Loctite #271 to thethreads of the cap screw; thentighten the nut to 45 ft-lb.

7. Place the cotter pin into the ski capscrew and spread the pin.

8. Repeat procedure for the other ski.

Rail Wear StripsArctic Cat recommends that the wearstrips be checked weekly and replaced asnecessary. Measure the wear strips at 25.4cm (10 in.) intervals. Wear strips must be10.7 mm (0.42 in.) thick or thicker.

If wear strip measurements are less thanspecified, replacement of both wear stripsis necessary to prevent premature trackclip wear and possible track damage.Take the snowmobile to an authorizedArctic Cat Snowmobile dealer for thisservice. This service is at the discretionand expense of the snowmobile owner.

Each time a new set of wear strips areinstalled, they should be tempered. Tem-per the wear strips by driving the snow-mobile for approximately a mile on ahard pack trail; then immediately driveinto deep snow and allow the wear stripsto cool. Repeat the procedure (warmingup the wear strips; then cooling themdown) two or three times.

NOTE: The rail wear strips will wearrapidly if the snowmobile is operatedon terrain on which the snow cover isminimal. Loose snow is required tocool and lubricate the wear strips andprevent accelerated wear.

Performance TipsOperating a high performance snowmo-bile requires a special attention that is notrequired by a low performance snowmo-bile. Often, a minor adjustment willresult in a large increase in performance.This section is intended to highlightminor conditions that adversely affectperformance and the adjustments neededto correct them. Be sure, however, tothoroughly read and understand thisentire manual especially the section onspark plugs, track tension and alignment,and suspension.

DRIVE BELT — This link between theengine and drive train is often the mostneglected component. The drive belt musthave the proper fit in the drive clutch anddriven pulley. Proper fit is when the topsurface of the drive belt is flush with thetop or up to 1/16 in. higher than the drivenpulley sheaves (with the sheaves fullyclosed). If drive belt deflection is abovespecification, the snowmobile will bog andlack power at engagement and will have aslower maximum speed. For good perfor-mance, proper belt deflection is critical. Tocorrect this condition, first determine if thedrive belt is within specifications (seeDrive Belt sub-section) and replace ifworn or too long. Always run the drivebelt in the same direction. Installing thedrive belt so the part number can be readwill ensure that the drive belt is alwaysrun the same direction.

DRIVE BELT DEFLECTION — Drivebelt length, condition, and deflection areall important for peak performance. Tocheck and adjust drive belt deflection,remove the belt guard; then use the fol-lowing procedure.

NOTE: It may be necessary toremove a shim washer from betweenthe driven pulley sheaves to allow thedriven pulley to close tighter. Addingshim washers will decrease beltdeflection and removing shim wash-ers will increase belt deflection. Avail-able shim washers from Arctic Cat arep/n 0648-714 (0.090 in.) - one includedin the tool kit, p/n 0648-715 (0.030 in.),and p/n 0648-716 (0.060 in.).

NOTE: Removing/adding shimwashers may be done by the snow-mobile owner if qualified to do so. Ifthe owner does not feel qualified,take the snowmobile to an autho-rized Arctic Cat Snowmobile dealerfor this service. This service is at thediscretion and expense of the snow-mobile owner.

1. Turn the engine off; then open theaccess panel.

2. Make sure the drive belt is sitting atthe top of the driven pulley sheaves.

3. Place a straightedge on top of thedrive belt. The straightedge shouldreach from the driven clutch to thetop of the driven pulley.

4. Using a stiff ruler centered betweenthe drive clutch and driven pulley,push down on the drive belt justenough to remove all slack. Note theamount of deflection on the ruler atthe bottom of the straightedge. Thedeflection should be at 1 1/4 in.

0743-319

NOTE: Push down on the belt withthe ruler only until the bottom of thebelt flexes upward; then read theamount of deflection.

5. To correct drive belt deflection,remove the sheave adjuster from thepulley, remove or add shim washersto the adjuster, and install theadjuster.

NOTE: Adding shim washers willdecrease belt deflection; removingshim washers will increase beltdeflection.

6. Install the belt guard; then close theaccess panel.

62

DRIVE CLUTCH AND DRIVENPULLEY — Keeping the drive clutchand driven pulley clean should be the pri-mary consideration of the operator. Thedrive clutch and driven pulley can becleaned of any drive belt accumulationusing compressed air. The sheaves can becleaned using a clean cloth and parts-cleaning solvent.

DRIVE CLUTCH/DRIVEN PULLEYOFFSET — If premature drive belt wearis experienced or if the drive belt turnsover, offset must be checked. Also, offsetmust be checked whenever either thedrive clutch or driven pulley is serviced.

NOTE: For checking offset, it isnecessary to use Clutch AlignmentBar (p/n 0644-496). This special toolcan be purchased from an autho-rized Arctic Cat snowmobile dealer.

To check offset, use the following proce-dure.

1. Open the left-side access panel; thenremove the belt guard.

2. Install the clutch alignment barbetween the drive clutch sheaves.

3. Allow the bar to rest on the driveclutch shaft and against the outsideedge of the driven pulley stationarysheave.

NOTE: The alignment bar mustextend beyond the front edge of thedrive clutch.

4. With the bar against the outside edgeof the driven pulley stationarysheave at points A and B, the barshould just clear the inside edge ofthe stationary sheave of the driveclutch and rest on the stationaryshaft at point C with a maximum0.060 in. clearance at point C. Atthis point, measurement betweenpoints A and C should be 1.507 in.(with a maximum 0.060 in. clear-ance). If the bar either will not clearthe inside edge or is more than thespecified amount, the offset must becorrected.

0745-177

NOTE: If the offset is out of speci-fication, take the snowmobile to anauthorized Arctic Cat Snowmobiledealer for drive system evaluationand/or servicing. This service is atthe discretion and expense of thesnowmobile owner.

DRIVE CLUTCH/DRIVEN PULLEYPARALLELISM — If premature drivebelt wear is experienced or if the drivebelt turns over, parallelism must bechecked. Also, parallelism must bechecked whenever either the drive clutchor driven pulley is serviced.

NOTE: For checking parallelism, itis necessary to use Clutch Align-ment Bar (p/n 0644-509). This specialtool can be purchased from anauthorized Arctic Cat Snowmobiledealer.

To check parallelism, use the followingprocedure.

1. Remove the drive belt; then open thedriven sheaves and place clutchalignment bar between the sheaves.Release the sheaves.

2. Check the parallelism of the driveclutch/driven pulley using the paral-lelism bar and reference points Xand Y with the parallelism barbetween the driven sheaves. Using acaliper or a machinist’s scale, mea-sure X and Y from the back side ofthe parallelism bar to the back sideof the drive clutch sheave. Measure-ment Y must be 0.060 in. ± 0.020 in.more than measurement X, but Ymust not exceed measurement X bymore than 0.100 in.

0744-609

3. If parallelism is not within specifica-tions, the parallelism must be cor-rected by first loosening all theengine mounting bolts (left side,front, and right top rear). Then, prythe front of the engine towards theMAG-side of the engine compart-ment. Next tighten the left-sidemounting bolts followed by the frontand right-top rear bolts. Re-checkthe parallelism. If still out of specifi-cation, repeat correction procedure.

CARBURETOR MAIN JETS(F570 Model) — Proper carburetion isabsolutely necessary to obtain peak per-formance. Since ambient temperature andoperating altitude both affect the main jetsize needed for optimum engine perfor-mance, the main jets MUST be changedwhenever the temperature changes 20° For whenever operating altitude varies bymore than 1000 feet. The Carburetor JetChart on the belt guard of the snowmo-bile identifies the proper main jets to useunder all operating temperatures and alti-tudes. Follow the Carburetor Jet Chartcarefully to obtain peak engine perfor-mance and avoid engine damage.

GASOLINE — On the CFR 1000/F570/F5/F6 models for optimum performance,it is not necessary to exceed the recom-mended 87 octane gasoline. Using ahigher octane gasoline will not increaseoverall performance. It is recommendedthat 91 octane (minimum) gasoline beused in the CFR 800/F8 models.

3. Place the rear of the snowmobile upon a shielded safety stand.

NOTE: On the F570 model prior tostep 4, carefully pry the intake bootspartially over the carburetor inlets.

4. Start the engine and allow to idle;then on the CFR/F5/F6/F8 models,pry the intake boot forward.

5. Spray an Engine Storage Preserverinto the intakes until the engineexhaust starts to smoke heavily oruntil the engine starts to drop inRPM. Turn engine off. Install theintake boots.

6. Plug the exhaust system outlet witha clean cloth.

7. With the ignition switch in the OFFposition:

A. Disconnect the high tensionleads from the spark plugs; thenremove the plugs, connect themto the leads, and ground them onthe cylinder heads.

B. Pour 29.5 ml (1 fl oz) of SAE#30 petroleum-based oil intoeach spark plug hole and pull therecoil starter handle slowly about10 times.

C. Install the spark plugs and con-nect the high tension leads.

NOTE: On the F570 model, drainthe gas from each carburetor floatchamber.

8. Fill the gas tank to its rated capacity;then add Arctic Cat Fuel Stabilizer(p/n 0436-907) to the gas tank fol-lowing directions on the containerfor the stabilizer/gasoline ratio.Tighten the gas tank cap securely.

9. Flush the gear case and replace thelubricant (see Lubrication section).

10. Remove the drive belt from the driveclutch/driven pulley. Lay the belt ona flat surface or slide it into a card-board sleeve to prevent warping ordistortion during storage.

11. Clean and inspect the drive clutchand driven pulley.

12. Apply light oil to the upper steeringpost bushing and shafts of the shockabsorbers.

13. Lubricate the rear suspension, spin-dles, and steering arms with all-tem-perature grease.

CAUTIONDo not run the engine without thebelt guard in place and secured.
