(c) Fill fuel tank outdoors with extreme care,Never fill fuel tank Indoors.

(d) Replace fuel tank cap securely and wipe upspilled fuel.

(e) Never store fuel or snow thrower with fuel Inthe tank Inside of a building where fumes mayreach an open flame or spark.

(f) Check fuel supplybefore each use,anowlngspace forexpenslonasthe heatofthe engine(motor) and/or suncan cause fuel to expend.

5. Use extsnsloncords snd racaptaclesasspecifiedby the manufacturer for all snow throwerswitheiactrlc drive motors orelectric startingmotors.

6. Adjust the snow thrower height to clear gravel orcrushed rock surfaces,

7. Never aftempt to make any edjustmsnts while theengine (motor) Is running (except whenspecifically recommended by the manufacturer).

8. Let engine (motor) and snow thrower adjust tooutdoor temperatures before starting to clearSNOW.

9. Always weer safety glasees or eye shields du ring

operetlon or while performing an adjustment orrepair to protect eyes from foreign objects thatmay be thrown from the snow thrower.

OPERATION

1. Do not put hands or feet near or under rotatingparts. Keepclear of the discharge openingat alltimes.

2. Exercise extreme cautio n when operating on orcrossing gravel drives, walks, or roads. Stay alertfor hidden hazards or traffic.

3. After striking a foreign object, stop the engine(motor), remove the wire from the spark plug,disconnect the cord on electric motors,thoroughly Inspect the snow thrower for anydamage, and repair the damage before restartingand operating the snow thrower.

4. If the snow thrower should start to vibrate

abnormally, stop the (motor) and checkImmediately for the cause. Vlbretlon Is gsnerelly

a warning of trouble.

5. Stop the snglne (motor) wheheveryou leavetheoperating position, before unclogging the auger/Impeller housing or dlsnherge guide, and whenmaking a ny repairs, adjustments, or Inspections.

6. When cleaning, repairing, or Inspecting, makecartaln the auger/impeller and all moving partshave stopped. Disconnect the spark plug wireand keep the wire away from the plug to preventaccidental starting.

7. Take all possible precautions when leaving thesnow thrower unattended. Disengage the auger/Impeller, shift to neutral, stop engine, andremove key.

SAFETY RULES

8. DOnot run the engine indoors, except when startingthe engine and for transporting the snow thrower Inor out of the building. Open the outside doors;exhaust fumes aredangerous (containing CARBONMONOXIDE, an ODORLESS and DEADLY GAS).

9. Do not clear snow across the face of slopes.Exercise caution when changing direction onslopes. Do not attempt to clear steep slopes.

10. Never operate the snow thrower without properguards, plates or other safety protective devicesIn place.

11. Never operate the snow thrower near glassenclosures, automobiles, window wells,drop-offs, and the like wit hour proper adjustmentof the snow discharge angle. Keep children andpets away.

12. Do not overload the machine capacity byattempting to clear snow at too fast a rate.

13. Neveroperatethesnowthrowerat hlghtransportspeeds on slippery surfaces. Look behind anduse care when becking.

14. Never direct dlscherge at bystanders or allowanyone In front of the snow thrower.

15. Disengage power to the augerllmpeller whensnow thrower Is transported or not In use.

16. Use only sttachments and accessories approvedby the manufacturer of the snow thrower (suchas tire chains, electric start kits, etc.).

17. Never operate the snow thrower without goodvlslblnty or light. Always be sure of your footing,and keep a firm hold on the handles. Walk; neverrun.

MAI'NTENANCE AND STORAGE

1. Check shear bolts and other bolts at frequentimproper tightness to be sure the snow throweris In safe working condition.

2. Never store the snow thrower with fuel in the fueltank inside a building whers Ignition sourcee arepresent such as hot water and space heaters,clothes dryers, and the llke. Allow the engine tocool before storing In any enclosure.

3. Always •refer to operator's manual instructionsfor Important details If the snow thrower is to bestored for an extended period.

4. Maintain or replace safety and Instruction labels,as necessary.

5. Run the snow thrower a few minutes afterthrowing snow to prevent freeze-up of the auger/impeller.

WARNING

This snow thrower Is for use on sidewalks,driveways, and other ground level surfaces.

CAUTION should be exercised while using onsteep sloping surfaces. DO NOT USE SNOWTHROWER ON SURFACES ABOVE GROUNDLEVEL such as roofs of residences, garages,porches or other such structures or buildings.

SERVICE AND ADJUSTMENTSCAUTION: ALWAYS DISCONNECTTHESPARK PLUG WIRE AND TIE BACKAWAY FROMTHE PLUG BEFORE MAK-ING ANY ADJUSTMENTS OR REPAIRS.

TO ADJUST SKID HEIGHT

Thissnowthroweris equippedwithtwo heightadjustmentskids,located on the outsideof the auger housing(SeeFig.20).These skidselevatethefront of thesnowthrower.

For normalhard sudaces, adjustthe skids as follows:

• Check tirepressure(14to 17 pounds).See sideoftirefor maximuminflation.Donotexceed maximumpres-sureon sideof tire.

• Place the extra shear bolts supplied(found in partsbag) under each end of the scraperbar near but notunderthe skid.

• Loosen the skid mountingnuts (See Fig. 20) andadjust the skids up to bring the front of the snowthrowerdown. Re-tightenthe mounting nuts.

• Set the skid on the other sideat the same height.

Forrockyoruneven surfaces,adjustthe skidsas follows:

• Raise the front of the snowthrower by movingtheskids down. This will help prevent rocks and otherdebrisfrombeingpickedup andthrownbythe auger.

NOTE: Be surethatsnowthrowerissetat sameheightonboth sides.

TOADJUSTSCRAPER BAR

Afterconsiderableuse,the metal scraper bar willhave adefinitewear pattern. The scraperbar inconjunctionwiththe skids shouldalwaysbe adjustedto allow1/8"betweenthe scraperbar and the sidewalkor area to be cleaned.The scraper bar may have to be returned to its originallowersettingto maintaintheoriginalperformancelevel.Toadjust:

• Positionthe snowthroweron a level sudace.

• Make sureboth tiresare equallyinflated.

• Loosen the carriage bolts and nuts securing thescraperbar to the auger housing.

• Adjustthe scraper bar to the properposition.

• Tightenthecarriagebolts and nuts,making surethatthe scraperbar is parallelwiththe workingsurface.

For extended operation, the scraper bar may bereversed. Ifthe scraper bar must be replaceddue towear,removethecarriage bolts andnutsandinstallanew scraperbar.

SERVICE AND ADJUSTMENTSTO ADJUST THE CLUTCH CONTROLCABLES

Periodic adjustmentof the cables may be required duetonormalstretch andwear on the belts. Tocheckfor correctadjustment, disconnect "Z" Fittingat clutch lever, moveclutch lever to the full forward position, just contacting theplastic bumper. The control cablesare correctly adjustedwhen the centerof the "Z" fitting is between the center andtop of the hole and there is no droop in the cable (See Fig.22). If adjustment is necessary:

• Remove fuel from tank, and stand blo_'er on end.

• Pull rubber boot off the top of the spring. Push thecable through the spring(See Fig. 23) to expose thethreaded portionof the cable.

• Holdthe squareendofthethreadedportionwithpliersand adjustthe Iocknutinoroutuntil theexcessslackis removed.

• PuUthe cableback thmughthe spring andconnectthecable.

• Do the same for the other lever cable, if needed•

NOTE" Whenever the traction drive or auger belts areadjusted or replaced, the cables will need to be adjusted.

TO ADJUST BELTSBeltsstretchduring normal use. If you need to adjustthebeltsdue to wear or stretch, proceedas follows:

AUGER DRIVE BELT (See Fig. 25)

If your snow thrower will not dischargesnow,check thecontrol cable adjustment. If it is correct, then check thecondition of the auger drive belt. It may be loose ordamaged. Ifit isdamaged,replaceit.SeeToReplaceBeltsparagraph on p_ge 21. If the auger drive belt is loose,adjust as follows:

• Disconnectthe sparkplugwire.

• Remove the beltcover (See Fig.26).• Loosenthe nuton the idlerpulley (See Fig. 24) and

move the pulleytoward the belt about 1/8".

• TKjhtenthe nut.

• Pressthe augerdrive lever.Checkthetensiononthebelt (opposite auger idler pulley). The belt shoulddeflect about 1/2" with moderate pressure(See Fig.24).

NOTE: You may have to move the auger idler.pulleymere than once to obtain the correct tension.

• Replace the belt cover.
