OPERATE YOUR SAW SAFELY• Do not operate with one hand. Seri-

ous injury to the operator, helpers, orbystanders may result from one-handed operation. A chain saw is in-tended for two-handed use.

• Operate the chain saw only in a well-ventilated outdoor area.

• Do not operate saw from a ladder orin a tree.

• Make sure the chain will not makecontact with any object while startingthe engine. Never try to start the sawwhen the guide bar is in a cut.

• Do not put pressure on the saw, es-pecially at the end of the cut. Doingso can cause you to lose controlwhen the cut is completed.

• Stop engine before setting saw down.• Hand carry saw only when engine is

stopped. Carry with muffler awayfrom body; guide bar & chain project-ing behind you; guide bar preferablycovered with a scabbard.

• Do not operate a chain saw that isdamaged, improperly adjusted, or notcompletely and securely assembled.Always replace bar, chain, handguard, chain brake, or other parts im-mediately if they become damaged,broken, or are otherwise removed.

MAINTAIN YOUR SAW IN GOODWORKING ORDER• Have all chain saw service per-

formed by a qualified service dealerexcept the items listed in the MAINTE-NANCE section of this manual.

• Make certain the saw chain stopsmoving when the throttle trigger isreleased. For correction, refer toCARBURETOR ADJUSTMENTS.

• Keep the handles dry, clean, andfree from oil or fuel mixture.

• Keep caps and fasteners securelytightened.

• Nonconforming replacement compo-nents or the removal of safety devicesmay cause damage to the unit andpossible injury to the operator or by-standers. Use only Craftsman acces-sories and replacement parts as rec-ommended. Never modify your saw.

• Maintain chain saw with care.• Keep unit sharp and clean for better

and safer performance.• Follow instructions for lubricating and

changing accessories.

• Check for damaged parts. Before fur-ther use of the chain saw, a guard orother part that is damaged should becarefully checked to determine that itwill operate properly and perform itsintended function. Check for alignmentof moving parts, binding of movingparts, breakage of parts, mounting andany other conditions that may affect itsoperation. A guard or other part that isdamaged should be properly repairedor replaced by a Sears Service Centerunless otherwise indicated elsewherein the instruction manual.

• When not in use, chain saws shouldbe stored in a dry, high or locked-upplace out of the reach of children.

• When storing saw, use a scabbard orcarrying case.

HANDLE FUEL WITH CAUTION• Do not smoke while handling fuel or

while operating the saw.• Eliminate all sources of sparks or

flame in areas where fuel is mixed orpoured.

• Mix and pour fuel in an outdoor areaand use an approved, marked con-tainer for all fuel purposes. Wipe upall fuel spills before starting saw.

• Move at least 10 feet (3 meters) fromfueling site before starting.

• Turn the engine off and let saw coolin a non-combustible area, not ondry leaves, straw, paper, etc. Slowlyremove fuel cap and refuel unit.

• Store the unit and fuel in a cool, drywell ventilated space where fuel va-pors cannot reach sparks or openflames from water heaters, electricmotors or switches, furnaces, etc.

GUARD AGAINST KICKBACK

Follow all safety rules to help avoidkickback and other forces which canresult in serious injury.

_._ _,_ Kickback Path

k_...:+j._,_ Avoid Obstructions

Clear The Worm

A411 WARNING: Avoid kickback whichcan result in serious injury. Kickbackis the backward, upward or sudden for-ward motion of the guide bar occurringwhen the saw chain near the upper tipof the guide bar contacts any objectsuch as a log or branch, or when thewood closes in and pinches the sawchain in the cut. Contacting a foreignobject in the wood can also result inloss of chain saw control.• Rotational Kickback can occur

when the moving chain contacts anobject at the upper tip of the guidebar. This contact can cause thechain to dig into the object, whichstops the chain for an instant. Theresult is a lightning fast, reversereaction which kicks the guide bar upand back toward the operator.

• Pinch-Kickback can occur when thethe wood closes in and pinches themoving saw chain in the cut alongthe top of the guide bar and the sawchain is suddenly stopped. This sud-den stopping of the chain results in areversal of the chain force used tocut wood and causes the saw tomove in the opposite direction of thechain rotation. The saw is driven

straight back toward the operator.• Pull-In can occur when the moving

chain contacts a foreign object in thewood in the cut along the bottom ofthe guide bar and the saw chain issuddenly stopped. This sudden stop-ping pulls the saw forward and awayfrom the operator and could easilycause the operator to lose control ofthe saw.

REDUCE THE CHANCE OFKICKBACK• Recognize that kickback can happen.

With a basic understanding of kick-back, you can reduce the element ofsurprise which contributes to acci-dents.

• Never let the moving chain contactany object at the tip of the guide bar.

• Keep working area free from obstruc-tions such as other trees, branches,rocks, fences, stumps, etc. Eliminateor avoid any obstruction that your sawchain could hit while cutting.

• When cutting a branch, do not let theguide bar contact another branch orother objects around it.

• Keep saw chain sharp and properlytensioned. A loose or dull chain can

increase the chance of kickback. Fol-low manufacturer's chain sharpeningand maintenance instructions. Checktension at regular intervals, but neverwith engine running. Make sure chainbrake nuts are securely tightened.

• Begin and continue cutting at fullspeed. If the chain is moving at aslower speed, there is greater chanceof kickback occurring.

• Use extreme caution when reenteringa cut.

• Do not attempt cuts starting with thetip of the bar (plunge cuts).

• Watch for shifting logs or other forcesthat could close a cut and pinch or fallinto chain.

• Use the specified Reduced-KickbackGuide Bar and Low-Kickback Chain.

Avoid Pinch-Kickback:• Be extremely aware of situations or

obstructions that can cause materialto pinch the top of or otherwise stopthe chain.

• Do not cut more than one log at atime.

• Do not twist saw as bar is withdrawnfrom an undercut when bucking.

Avoid Pull-In:• Always begin cutting with the engine

at full speed and the saw housingagainst wood.

• Use wedges made of plastic or wood.Never use metal to hold the cut open.

KICKBACKSAFETY FEATURES

WARNING: The following featuresare included on your saw to help reducehazard of kickback; however, such fea-tures will not totally eliminate this danger.Do not rely only on safety devices. Fol-low all safety rules to help avoid kick-back and other forces which can result

in serious injury,

• Front Hand Guard: designed to reducethe chance of your left hand contact-ing the chain if your hand slips off thefront handlebar.

• Position of front and rear handlebars:designed with distance between han-dles and "in-line" with each other. Thespread and "in-line" position of thehands provided by this design worktogether to give balance and resis-tance in controlling the pivot of thesaw back toward the operator if kick-back occurs.

• Reduced-Kickback Guide Bar: de-signed with a small radius tip whichreduces the size of the kickback dan-ger zone on the bar tip. This type barhas been demonstrated to significantlyreduce the number and seriousness ofkickbacks when tested in accordancewith ANS! B175.1.

AI_, WARNING: WE DO NOT REP-

RESENT AND YOU SHOULD NOT AS-SUME THAT THE CHAIN BRAKE WiLLPROTECT YOU IN THE EVENT OF AKICKBACK. Kickback is a lightning fastaction which throws the bar and rotat-ing chain back and up toward the op-erator. Kickback can be caused by al-lowing contact of the bar tip in thedanger zone with any hard object.Kickback can also be caused bypinching the saw chain along the topof the guide bar. This action may pushthe guide bar rapidly back toward theoperator. Either of these events maycause you to lose control of the sawwhich could result in serious injury oreven death. DO NOT RELY UPON ANYOF THE DEVICES BUILT INTO YOURSAW. YOU SHOULD USE THE SAWPROPERLY AND CAREFULLY TO AVOIDKICKBACK. Reduced-kickback guidebars and low-kickback saw chains re-duce the chance and magnitude ofkickback and are recommended. Yoursaw has a low kickback chain and bar

as original equipment. Repairs on achain brake should be made by an au-thorized Sears Service Center. Take

your unit to the place of purchase ortoyour nearest Sears Service Center.• Tip contact in some cases may cause

a lightning fast reverse REACTION,kicking guide bar up and back towardoperator.

• Pinching the saw chain along the topof the guide bar may push the guidebar rapidly back toward the operator.

• Either of these reactions may causeyou to lose control of the saw whichcould result in serious injury. Do notrely exclusively upon safety devicesbuilt into your saw.

,_L WARNING: Be sure to read the

fuel handling information in the safetyrules section of this manual before youbegin. If you do not understand thefuel handling information do not at-tempt to fuel your unit. Seek help fromsomeone that does understand the in-formation or call the customer assis-tance help line at 1-800-235-5878.

GUIDE BAR AND CHAIN OILThe bar and chain require lubrication.The chain oiler provides continuouslubrication to the chain and guide bar.Be sure to fill the bar oil tank when youfill the fuel tank (Capacity = 6.8 ft. oz.).Lack of oil will quickly ruin the bar andchain. Too little oil will cause overheat-ing shown by smoke coming from thechain and/or discoloration of the bar.

For maximum guide bar and chain life,we recommend you use Craftsmanchain saw bar oil. If Craftsman bar oilis not available, you may use a goodgrade SAE 30 oil until you are able toobtain Craftsman brand. The oil outputis automatically metered during opera-tion. Your saw will use approximatelyone tank of bar oil for every tank of fuelmix. Always fill the bar oil tank whenyou fill the fuel tank.FUELING ENGINE

,_L WARNING: Remove fuel capslowly when refueling.This engine is certified to operate onunleaded gasoline. Before operation,gasoline must be mixed with a goodquality 2-cycle air-cooled engine oil.We recommend Craftsman brand oil.Mix gasoline and oil at a ratio of 40:1.A 40:1 ratio is obtained by mixing 3.2ounces of oil with 1 gallon of unleadedgasoline. Included with this saw is a3.2 ounce container of Craftsmanbrand oil. Pour the entire contents of

this container into 1 gallon of gasolineto achieve the proper fuel mixture.DO NOT USE automotive oil or boat oil.These oils will cause engine damage.When mixing fuel follow the instruc-tions printed on the oil container.

Once oil is added to the gasoline,shake container momentarily to assurethat the fuel is thoroughly mixed. Al-ways read and follow the safety rulesrelating to fuel before fueling your unit.IMPORTANT

Experience indicates that alcoholblended fuels (called gasohol or usingethanol or methanol) can attract mois-ture which leads to separation andformation of acids during storage. Acidicgas can damage the fuel system of anengine while in storage. To avoid engineproblems, the fuel system should beemptied before storage for 30 days orlonger. Drain the gas tank, start the en-gine and let it run until the fuel lines andcarburetor are empty. Use fresh fuelnext season. See STORAGE instructionsfor additional information.

Never use engine or carburetor clean-er products in the fuel tank or perma-nent damage may occur.See the STORAGE section for addition-al information.CHAIN BRAKE

Ensure chain brake is disengaged bypulling the front hand guard back to-ward the front handle as far as pos-sible. The chain brake must be disen-gaged before cutting with the saw.

,_,WARNING: The chain must not

move when the engine runs at idlespeed. If the chain moves at idlespeed, refer to CARBURETOR ADJUST-MENT within this manual. Avoid con-tact with the muffler. A hot muffler cancause serious burns.

Release your grip on thefront handle and let the tip of the guidebar fall forward and contact the stump.When the tip of the bar hits the stump,the brake should activate.OPERATING TIPS• Check chain tension before first use

and after 1 minute of operation. SeeCHAIN TENSION in the MAINTENANCEsection.

• Cut wood only. Do not cut metal,plastics, masonry, non-wood buildingmaterials, etc.

• Stop the saw if the chain strikes aforeign object. Inspect the saw andrepair parts as necessary.

• Keep the chain out of dirt and sand.Even a small amount of dirt willquickly dull a chain and increase thepossibility of kickback.

• Practice cutting a few small logs us-ing the following steps. This will helpyou get the "feel" of using your sawbefore you begin a major sawing op-eration.

• Squeeze the throttle trigger and al-low the engine to reach full speedbefore cutting.

• Begin cutting with the saw frameagainst the log.

• Keep the engine at full speed theentire time you are cutting.

• Allow the chain to cut for you. Exertonly light downward pressure.

• Release the throttle trigger as soonas the cut is completed, allowingthe engine to idle. If you run thesaw at full throttle without a cuttingload, unnecessary wear can occur.

• To avoid losing control when cut iscomplete, do not put pressure onsaw at end of cut.

• Stop engine before setting sawdown.

TREE FELLING TECHNIQUES

'_ WARNING: Check for broken ordead branches which can fall while cut-ting causing serious injury. Do not cutnear buildings or electrical wires if youdo not know the direction of tree fall, norcut at night since you will not be able tosee well, nor during bad weather suchas rain, snow, or strong winds, etc.• Carefully plan your sawing operation

in advance.• Clear the work area. You need a

clear area all around the tree so youcan have secure footing.

• The chain saw operator should keepon the uphill side of the terrain as thetree is likely to roll or slide downhillafter it is felled.

• Study the natural conditions that cancause the tree to fall in a particulardirection. These conditions include:• The wind direction and speed.• The lean of the tree. The lean of a

tree might not be apparent due touneven or sloping terrain. Use aplumb or level to determine the di-rection of tree lean.

• Weight and branches on one side.• Surrounding trees and obstacles.

• Look for decay and rot. If the trunk isrotted, it can snap and fall toward theoperator.

• Make sure there is enough room forthe tree to fall. Maintain a distance of

2-1/2 tree lengths from the nearestperson or other objects. Enginenoise can drown out a warning call.

• Remove dirt, stones, loose bark,nails, staples, and wire from the treewhere cuts are to be made.

• After removing the wood from thenotch, make the felling cut on the op-posite side of the notch. This is doneby making a cut about two incheshigher than the center of the notch.This will leave enough uncut woodbetween the felling cut and the notchto form a hinge. This hinge will helpprevent the tree from falling in thewrong direction.

NOTE: Before felling cut is complete,use wedges to open the cut whennecessary to control the direction offall. To avoid kickback and chaindamage, use wood or plastic wedges,but never steel or iron wedges.

• Be alert to signs that the tree is readyto fall: cracking sounds, widening ofthe felling cut, or movement in the up-per branches.

• As tree starts to fall, stop saw, put itdown, and get away quickly on yourplanned retreat path.

• DO NOT use your saw to cut down apartially fallen tree. Be extremelycautious with partially fallen treesthat may be poorly supported. Whena tree doesn't fall completely, set the

saw aside and pull down the treewith a cable winch, block and tackle,or tractor.

CUTTING A FALLEN TREE(BUCKING)Bucking is tile term used for cutting afallen tree to the desired log size.

,_& WARNING: Do not stand on the

log being cut. Any portion can rollcausing loss of footing and control. Donot stand downhill of the log being cut.IMPORTANT POINTS• Cut only one log at a time.• Cut shattered wood very carefully;

sharp pieces of wood could be flungtoward operator.

• Use a sawhorse to cut small logs.Never allow another person to holdthe log while cutting and never holdthe log with your leg or foot.

• Do not cut in an area where logs,limbs, and roots are tangled. Draglogs into a clear area before cuttingthem by pulling out exposed andcleared logs first.

BUCKING TECHNIQUES

_, WARNING: If saw becomes

pinched or hung in a log, don't try toforce it out. You can lose control of thesaw resulting in injury and/or damageto the saw. Stop the saw, drive awedge of plastic or wood into the cutuntil the saw can be removed easily.Restart saw and carefully reenter thecut. Do not use a metal wedge. Do notattempt to restart your saw when it ispinched or hung in a log.

Use a wedge to remove pinched saw

Turn saw OFF and use a plastic orwooden wedge to force cut open.

Overcutting begins on the top side ofthe log with the bottom of the sawagainst the log. When overcutting uselight downward pressure.

tree to _imb or prune. Do not stand onladders, platforms, a log, or in any po-sition which can cause you to loseyour balance or control of the saw.

IMPORTANT POINTS• Watch out for springpoles.

Springpoles are small size limbswhich can whip toward you, or pullyou off balance. Use extreme cau-tion when cutting small size limbs.

• Be alert for springback from anybranches that are bent or underpressure. Avoid being struck by thebranch or the saw when the tensionin the wood fibers is released.

• Frequently clear branches out of theway to avoid tripping over them.

LIMBING• Limb a tree only after it is cut down.• Leave the larger limbs underneath

the felled tree to support the tree asyou work.

• Start at the base of the felled treeand work toward the top, cuttingbranches and limbs. Remove smalllimbs with one cut.

• Keep the tree between you and thechain.

• Remove larger branches with thecutting techniques described inBUCKING WITHOUT A SUPPORT.

PRUNING

_WARNING: Limit pruning to limbs

shoulder height or below. Do not cut ifbranches are higher than your shoul-der. Get a professional to do the job.• Make your first cut 1/3 of the way

through the bottom of the limb. Thiscut will make the limb sag so that itfalls easily on the second cut.

• Next make the second cut an over-cut all the way through the limb.

• Finish the pruning operation by usingan overcut so that the stump of thelimb protrudes 1 to 2 inches from thetrunk of the tree.

/_ Third cut 1 to 2inches from trunkof tree

CHAIN ADJUSTMENTSee CHAIN TENSION in MAINTENANCEsection.CARBURETOR ADJUSTMENT

_IWARNING: The chain will be

moving during most of this procedure.Wear your protective equipment and ob-serve all safety precautions. During thelow speed mixture adjustment recheckidle speed after each turn of the screw.The chain must not move at idle speed.Carburetor adjustment is critical and ifdone improperly can permanently dam-age the engine as well as the carbure-tor. If you require further assistance orare unsure about performing this proce-

dure, call our customer assistance helpline at 1-800-235-5878.Old fuel, a dirty air filter, dirty fuel filter, orflooding may give the impression of animproperly adjusted carburetor. Checkthese conditions before adjusting thecarburetor.

The carburetor has been carefully set atthe factory. Adjustments may be neces-sary if you notice any of the followingconditions:• Chain moves at idle. See IDLE

SPEED-T under adjusting procedure.• Saw will not idle. See IDLE SPEED-T

and LOW SPEED MIXTURE-L under

adjusting procedure.• Engine dies or hesitates when it

should accelerate. See ACCELERA-TION CHECK under adjustingprocedure.

• Loss of cutting power. See HIGHSPEED MIXTURE - H under adjustingprocedure.

There are three adjustment screws onthe carburetor. They are labeled H, L,and T. They are located in the area justabove the primer bulb.ADJUSTING PROCEDURECAUTION: Do not force plastic limitercaps on screws beyond the built-instops or damage will occur.Initial Settings1. Turn both mixture screws (L and H)

counterclockwise until they stop.2. Turn the idle speed screw (T)

clockwise until it stops. Then turn itcounterclockwise 4 and 1/2 turns.

3. Start engine and let it run for 3 min-utes, then proceed to adjustscrews according to the instruc-tions below. If engine performanceat initial settings is acceptable, nofurther adjustments are necessary.If engine does not start, refer to theTROUBLESHOOTING TABLE.If still unable to remedy situation,call 1-800-235-5878.

Idle Speed-TAllow engine to idle. If the chainmoves, idle is too fast. If the enginestalls, idle is too slow. Adjust speeduntil engine runs without chain move-ment (idle too fast) or stalling (idle tooslow).• Turn idle screw (T) clockwise to in-

crease engine speed.• Turn idle screw (T) counterclockwise

to decrease engine speed,

17

Low Speed Mixture-LAllow engine to idle. Then acceleratethe engine and note performance. Ifengine hesitates, bogs down, orsmokes during acceleration, turn lowspeed mixture screw (L) clockwise in1/16-turn increments until performanceis satisfactory. Repeat this procedureas necessary for proper adjustment.After completing adjustments, checkfor acceleration and chain movementat idle. Reset if necessary.High Speed Mixture-HDO NOT operate engine at full throttlefor prolonged periods while making ad-justments. Damage to the engine canoccur. Make a test cut. Based on per-formance of the saw while cutting, ad-just the high speed mixture setting in1/16-turn increments as follows:

• Turn the high speed mixture screw (H)clockwise until saw has good power inthe cut with no hesitation. Do not ad-

just by sound or speed, but judge byhow well the saw performs in the cut.

• Turn the high speed mixture screw (H)counterclockwise if the saw hasspeed, but dies in the cut or lackspower in the cut.

After completing adjustments, checkfor acceleration and chain movementat idle. Reset if necessary.Acceleration Check

If the engine dies or hesitates instead ofaccelerating, turn the low speed mixturescrew (L) counterclockwise until youhave smooth acceleration with no chainmovement at idle.

WARNING: Perform the followingsteps after each use:• Allow the engine to cool, and secure

the unit before storing or transport-ing.

• Store chain saw and fuel in a well

ventilated area where fuel vaporscannot reach sparks or open flamesfrom water heaters, electric motors orswitches, furnaces, etc.

• Store chain saw with all guards inplace and position chain saw so thatany sharp object cannot accidentallycause injury.

• Store chain saw well out of the reachof children.

SEASONAL STORAGE

Prepare your unit for storage at theend of the season or if it will not beused for 30 days or more.If your chain saw is to be stored for aperiod of time:• Clean saw thoroughly before stor-

age.• Store in a clean dry area.• Lightly oil external metal surfaces

and guide bar.• Oil the chain and wrap it in heavy pa-

per or cloth.

FUEL SYSTEM

Under FUELING ENGINE in the OPERA-TION section of this manual, see mes-

sage labeled IMPORTANT regardingthe use of gasohol in your chain saw.Fuel stabilizer is an acceptable alter-native in minimizing the formation offuel gum deposits during storage. Addstabilizer to the gasoline in the fueltank or fuel storage container. Followthe mix instructions found on stabilizercontainers. Run engine at least 5 min-utes after adding stabilizer.Craftsman 40:1,2-cycle engine oil (aircooled) is blended with fuel stabilizer. Ifyou do not use this Sears oil, you canadd a fuel stabilizer to your fuel tank.ENGINE• Remove spark plug and pour 1 tea-

spoon of 40:1,2-cycle engine oil (aircooled) through the spark plug open-ing. Slowly pull the starter rope 8 to10 times to distribute oil.

• Replace spark plug with new one ofrecommended type and heat range.

• Clean air filter.• Check entire unit for loose screws,

nuts, and bolts. Replace any dam-aged, broken, or worn parts.

• At the beginning of the next season,use only fresh fuel having the propergasoline to oil ratio.

OTHER• Do not store gasoline from one sea-

son to another.• Replace your gasoline can if it starts

to rust.
