Regard your snow blower as a piece ofpower equipment and be sure this isunderstood by all who operate it.

Never allow children or young teen-agers to operate the tractor and snowblower.

Be sure you know how to stop the trac-tor and auger at a moment's notice.

Instruct children to keep away from thearea of operation at all times.

Check the tractor and blower to makecertain both are in good operating con-dition"

FiIl gas tank out of doors and avoidspilling gasoline. Do not fill tank withgasoline while smoking or while engineis running.

Give complete and undivided attentionto the job at hand.

1. Whenever possible, discharge snow downwind.

Do not attempt to remove ice or hardpacked frozen snow.

Always overlap each pass slightly to as-sure complete snow removal.

Use extreme care when freeing a frozenor stuck auger or chute. Always turnoff the tractor first.If tractor is equipped with Hydraulls T,iff,operate with the lift lever in the "float"(full forward) position. Never apply downpressure to the snow blower. With thehydraulic lift lever in the ?'floatrr posi-tion, the skid shoes will remain on thesurface even though operating on uneventerrain.

METHODS OF SNOW REMOVAL

Fisure 2

A definite pattern of operation is requiredto thoroughly clean the snow area. Thispattern wiII avoid a second removal of snowand avoid blowing snow in unwanted places.Where it is possible to blow snow to rightand left, as on a long driveway, it is ad-vantageous to start in the middle. SeeFigure 2. Work from one end to the oppo-site end blowing snow to both sides without

NO SNOW PILED ON IEFT SIDE

Figure 3

changing direction of discharge chute. Ifsnow can only be blown to one side of thedriveway, start on the opposite side. SeeFigure 3. At the end of each pass, rotatechute to opposite side for the return pass.At the end of each succeeding pass, rotatechute to opposite side to maintain directionof throw into the same area.

TIRE CHAINS AND WHEEL WEIGHTS

The use of tire chains anC r,vheel weights,Figure 4, is recommended for snow re-moval operation. The extra traction re-sulting gives the tractor operator maneu-verability in handling heavy snow removaljobs. These accessories are sold by yourdealer and are not included with the snowblower.

The same wheel weights can also be attachedto the front of thetractorwhengardenplowingor tilling by adding the Model H18 FrontWeight Bracket Kit.

PREPARING FOR SNOW REMOVAL

Disengage the attachment driveclutch when starting engine andwhen transporting the snowblower. Before the first snow-fall, the area in which snow re-moval is to take place shouldbe cleared of all stones, sticks,etc., which might be picked upby the snowblower. OBSTACLESSUCH AS DRTVEWAY MARKERS,WATER OR GAS SHUT OFFS,

ETC" SHOULD BE MARKED SO THEIR LO-CATIONS UNDER THE SNOW ARE VERYOBVIOUS.

To become familiar with the controls, op-erate the tractor and snow blower in a cleararea before removing snow. The morefamiliar you become with the snow blower,the better results you wiil have in its use.

SNOW CONDITIONS

Snow removal conditions vary so greatlyfrom the first light fiuffy snowfall to wetor heavy snow that operating instructionsmust be flexible. The operator must op-erate according to depth of snow, wind di-rection, temperature, and surface conditions.

The auger speed and blowing distance aredirectly related to the engine speed. Formaximum removal volume and distance,maintain high engine RPM (three -quartersto fuII governed throttte). Operatingatlowerthrottle settings will reduce the blowing dis-tance and increase fuel economy. Alwaysoperate the tractor in low range for safe andefficient snow removal. The speed controllever should be operated to provide a groundspeed most compatible with the snow re-moval conditions.

In extremely deep snow, raise snow blowerinto transport and remove top layer first.Lower the snow blower to the ground andrepeat process to remove the balance ofsnow. Working with repeated passes intoand out of drifts will eventually move eventhe deepest of snow piles.

A light coat of wax applied to the insidesurfaces of the discharge chute anddeflectorwiII help to prevent snow and slush fromsticking. The inside of chute and deflectorshould be waxed several times during thesnow removal season. Use any good com-mercial grade of paste wax or spray sili-cone which is available from your dealeror from your local hardware store.

Allow ample engine warm up time beforestarting snow removal.

Best results are obtained when snow is re-moved as soon as possible aJter it falls.

Check each item covered in the "ADJUST-MENTS" and "MAINTENANCE" sections ofthis manual before operating the snow blower.

3. Skid Shoes - See Figure 6. Slottedmounting holes are provided to obtainthe oesired clearance between the baseof the auger housing and the surface ofthe area to be cleared. When operatingon a smooth surface such as cement orasphalt, the skid shoes can be set atthe lower end of the slots. ff operatingon a rough surface such as gravel orearth, the skid shoes should be set atthe upper end of the slots to preventforeign material from entering andpossibly damaging the snow blower.

4" Auger Drive Chain - The chain slack atthe lower section should be held to be-tween 3/8" and 1/2" under normal fingerpressure midway between the drivesprockets. Adjust the idler block bolton the upper chain section, up or down,as necessary to maintain proper slack.Should the available adjustment for theidler block be used up, the overall chainIength can be decreased by removing oneIink and adding the offset link furnishedwith snow blower. The idler block canalso be rotated or turned around if thechain wears in excessively.

MAINTENANCE

Never attempt to service or makeadjustments while the snowblower or tractor is running.

Grease the discharge chute control crank,chute guides and the chute base ring. Figure1, daily to keep the crank turning freely.

Once a month during season or every 25

operating hours, lubricate the auger drivechain with Case Heavy Duty Chain and CableLubricant available through your Case Com-oact Tractor Dealer.

In order to reduce thesizeof theshippingcarton and hold transportation costs to aminimum the Mounting Bracket is de-tached from the Auger Assembly.

Position the Mounting Bracket betweenthe Auger Adapter P1ates as shown inFigure 10. hsert a spacer in eachof theAdapter Plates. Bolt the MountingBracket to the Adapter Plates with theplain washers to the outside and locknuts at the inside.

Three round head bolts are furnished toattach the chute guides to the dischargespout instead of two as shown in Figure14. InstaII the bolts at the two sideguides with the round heads to the in-side. For ease of assembly, install thefront guide boit with the nut and lock-washer to the inside.

The heavy duty skid shoes can be rotatedfrom one side of the blower to the otherfor increased life when the leading edgeswear down.The shoes can be installed with the skidsfacing either inward or outward. If theskids are installed inward they wiII pro-tect the cutting edge by keeping it 3/16"higher than the skids when they are ad-justed to the "minimum" clearance po-sition" If the skids are installed inwardthe nuts and lockwashers must be to theinside to provide a "smooth" outsidesuriace.

If the shoes are installed with the skidsto the outside they can be adjusted fur-ther upward if desired to place the cut-ting e$ge in direct contact with a hardlevel surface such as a concrete or as-phalt driveway. If installed in this man-ner the nuts andlockwashers canbetotheoutside. This installation is not recom-mended when operating on dirtrgraveloruneven surfaces.

The replaceable cutting edge can also bereversed for increased life when theleading side_ wears down.

Auger Drive Chain Adjustment -- Theidler block described on page 6, para-graph 4, has been eliminated. The twoauger mounting hubs have four holes in aneccentric circle around the auger mount-ing shaft. The hubs also have an ori-entation hole near the shaft. Chainslackat the lower section should be heldtobe-tween 3/8" and lf 2" under normalfingerpressure midway between the drivesprockets.

When adjustment is necessary, removethe two bolts from the right hand mount-ing hub and rotate the hub in either di-rection until correct chain tension isobtained and reinstall the two bolts. lm-portant - To keep the ehain in line withthe auger sprocket, rotate the left handmounting hub to locate the orientationhole in the same position as the righthand hub.

Turn the auger to make certain there isno interference with the housing. Ifinterference is encountered, remove thetwo bolts from the right hand mountinghub and rotate the hub in the oppositedirection until correct tension is obtain-ed. Reset the left hand hub to placethe orientation hole in the same locationas the right hand hub.

Should the available adjustment onthe auger mounting hubs be usedup, the overall chain length can bedecreased by removing the offset(half) lirk from the chain.
