the manufacturer of the snow thrower (such as wheel  
weights, counterweights, cabs, tire chains, electric  
start kits, etc.).  
If the unit should start to vibrate abnormally, stop the  
engine (motor) and check immediately for the cause.  
Vibration is generally a warning of trouble.  
Stop the engine (motor) whenever you leave the oper-  
ating position, before unclogging the auger/impeller  
housing or discharge chute and when making any  
repairs, adjustments, or inspections.  
Never operate the snow thrower without good visibility  
or light. Always be sure of your footing and keep a firm

TO ADJUST SKID PLATES  
BEFORE STARTING THE ENGINE  
CHECK ENGINE OIL LEVEL  
NOTE:Thewrenchprovidedinyourpartsbagmaybeused  
to adjust the skid plates.  
The engine on your snow thrower has been shipped, from  
the factory, already filled with oil.  
Skid plates are located on each side of the auger housing  
and adjust the clearance between the scraper bar and the  
ground surface. Adjust skid plates evenly to proper height  
for current surface conditions. For removal of snow in  
normal conditions, such as a paved driveway or sidewalk,  
place skid plates in the highest position (lowest scraper  
clearance)togivea1/8"clearancebetweenthescraperbar  
and the ground. Use a middle position if the surface to be  
cleared is uneven.  
1. Check engine oil with snow thrower on level ground.  
2. Remove oil fill cap/dipstick and wipe clean, reinsert the  
dipstickandscrewtight,waitforafewseconds,remove  
and read oil level. If necessary, add oil until “FULL”  
mark on dipstick is reached. Do not overfill.  
Tochangeengineoil, seeTOCHANGEENGINEOIL”  
in the Maintenance section of this manual.  
NOTE: It is not recommended to operate the snow thrower  
over gravel or rocky surfaces. Objects such as gravel,  
rocks or other debris, can easily be picked up and thrown  
by the impeller, which can cause serious personal injury,  
property damage or damage to the snow thrower.  
ADD GASOLINE  
Fillfueltanktobottomoftankfillerneck. Donotoverfill.  
Use fresh, clean, regular unleaded gasoline with a  
minimum of 87 octane. Do not mix oil with gasoline.  
Purchase fuel in quantities that can be used within 30  
days to assure fuel freshness.  
If snow thrower must be operated over gravel surface,  
use extra caution and be sure skid plates are adjusted  
to lowest (highest scraper clearance) position.  
WARNING: Wipe off any spilled oil or  
fuel. Do not store, spill or use gasoline  
near an open flame.  
1. Shut off engine and wait for all moving parts to stop.  
2. Adjust skid plates by loosening the rear 1/2" hex nut  
only, then moving skid plate to desired position. Be  
surebothplatesareadjustedevenly. Tightensecurely.  
CAUTION: Alcohol blended fuels (called gaso-  
hol or using ethanol or methanol) can attract  
moisture which leads to separation and forma-  
tion of acids during storage. Acidic gas can  
damage the fuel system of an engine while in  
storage. To avoid engine problems, the fuel  
systemshouldbeemptiedbeforestorageof30  
days or longer. Drain the gas tank, start the  
engine and let it run until the fuel lines and  
carburetor are empty. Use fresh fuel next  
season. See Storage Instructions for addi-

OPERATION  
TO START ENGINE  
SNOW THROWING TIPS  
Be sure fuel shut-off valve is in the OPEN position.  
Always operate the snow thrower with the engine at full  
throttle. Full throttle offers the best performance.  
Your snow thrower engine is equipped with a recoil starter.  
COLD START  
Goslowerindeep,freezingorheavywetsnow.Usethe  
drive speed control, NOT the throttle, to adjust speed.  
1. Insert safety ignition key into the ignition slot until it  
clicks. DO NOT turn the key. Keep the extra safety  
ignition key in a safe place.  
It is easier and more efficient to remove snow immedi-  
ately after it falls.  
The best time to remove snow is the early morning. At  
this time the snow is usually dry and has not been  
exposed to the direct sun and warming temperatures.  
2. Place throttle control in FAST position.  
3. Rotate choke control to FULL position.  
4. Push the primer four (4) times if the temperature is  
below 15°F, or two (2) times if temperature is between  
15° and 50°F. If temperature is above 50°F, priming is  
not necessary.  
Slightly overlap each successive path to ensure all  
snow will be removed.  
Throw snow downwind whenever possible.  
Adjust the skid plates to proper height for current snow  
conditions. See “TO ADJUST SKID PLATES” in this  
section of this manual.  
NOTE: Over priming may cause flooding, preventing the  
engine from starting. If you do flood the engine, wait a few  
minutes before attempting to start and DO NOT push the  
primer.  
For extremely heavy snow, reduce the width of snow  
removal by overlapping previous path and moving  
slowly.  
5. Pull recoil starter handle quickly. Do not allow starter  
rope to snap back.  
Keep engine clean and clear of snow during use. This  
will help air flow and extend engine life.  
6. Whentheenginestarts,releasetherecoilstarterhandle  
and slowly move the choke control to the OFF position.  
After snow-throwing is completed, allow engine to run  
for a few minutes to melt snow and ice off the engine.  
Allow the engine to warm up for a few minutes. Engine will  
not develop full power until it has reached normal operating  
temperature.  
Clean the entire snow thrower thoroughly after each  
use and wipe dry so it is ready for next use.  
WARM START  
WARNING: Do not operate snow  
thrower if weather conditions impair  
visibility. Throwing snow during a  
heavy, windysnowstormcanblindyou  
and be hazardous to the safe operation  
of the snow thrower.  
Follow the steps above, keeping the choke in the OFF  
position. DO NOT push the primer.  
BEFORE STOPPING  
Run the engine for a few minutes to help dry off any  
moisture on the engine.  
To avoid possible freeze-up of the starter, proceed as  
follows:  
1. While the engine is running, pull the recoil starter  
handle with rapid, full arm strokes three or four times.  
NOTE: The unusual sound made while pulling the recoil  
starter handle will not harm the engine or starter.  
IF RECOIL STARTER HAS FROZEN  
If the recoil starter has frozen and will not turn the engine,  
proceed as follows:  
1. Grasp the recoil starter handle and slowly pull as much  
rope out of the starter as possible.  
2. Release the recoil starter handle and let it snap back  
against the starter.  
If the engine still fails to start, repeat the above steps.

MAINTENANCE  
TO CHANGE ENGINE OIL  
V-BELTS  
Determine temperature range anticipated before next oil  
change. All oil must meet API service classification SF-SJ.  
Check V-belts for deterioration and wear after every 50  
hours of operation and replace if necessary. The belts are  
notadjustable. Replacebeltsiftheybegintoslipfromwear.  
(See “TO REMOVE BELT COVER” in the Service and  
Adjustments section of this manual).  
Be sure snow thrower is on level surface.  
Oil will drain more freely when warm.  
Catch oil in a suitable container.  
The V-belts on your snow thrower are of special construc-  
tion and should be replaced by original equipment manu-  
facturer (OEM) belts available from your nearest dealer.  
Using other than OEM belts can cause personal injury or  
damage to the snow thrower.  
NOTE: The left side wheel may be removed from snow  
thrower for easier access to the oil drain plug and place-  
ment of a suitable container. The unit tilted, resting on the  
frame with the left wheel removed, will help drain any oil  
trapped inside the engine. (See “TO REMOVE WHEELS”  
in the Service and Adjustments section of this manual).  
AUGER GEAR CASE  
The gear case was filled with lubricant to the proper  
level at the factory. The only time the lubricant needs  
attention is if service has been performed on the gear  
case.

SERVICE AND ADJUSTMENTS  
TO REPLACE BELTS  
HINT: Insert a 3/8" drive ratchet (in the “ON” position) into  
the square hole in idler arm and rotate ratchet clockwise to  
relieve tension.  
The auger and traction drive belts are not adjustable. If the  
belts are damaged or begin to slip from wear, they should  
be replaced. It is recommended that the belt(s) be replaced  
by a qualified service center.  
8. With tension relieved on idler, install new traction drive  
belt around pulleys and inside belt keepers.  
NOTE: It is recommended that both the auger and traction  
drive belt be replaced at the same time.  
9. Place auger belt around and inside the groove of auger  
pulley only.  
The V-belts on your snow thrower are of special construc-  
tion and should be replaced by original equipment manu-  
facturer (OEM) belts available from your nearest dealer.  
Using other than OEM belts can cause personal injury or  
damage to the snow thrower.  
10. While your assistant slowly raises handles to rejoin the  
auger housing and frame assembly, pull up on the  
auger belt and squeeze sides together above pulley so  
belt is fully seated in groove of pulley.  
11. Bring snow thrower completely together and check  
carefully for proper routing of belts. If auger belt has  
becomedislodgedfromthepulley(bycatchingtheidler  
arm bracket while bringing snow thrower together),  
separate the snow thrower and repeat step 10. Belt  
must be fully seated in pulley groove when bringing the  
snow thrower together.  
WARNING: Belt replacement requires  
separation of the snow thrower. While  
separating the auger housing from the  
frame assembly, it is important that an  
assistant stand in the operating posi-  
tionandholdthesnowthrowerhandles.

NOTE: To seal punctures or prevent flat tires due to slow  
leaks, tire sealant may be purchased from your local parts  
dealer. Tire sealant also prevents tire dry rot and corrosion.  
TO REMOVE WHEELS  
Remove the klik pin and remove wheel from axle.  
IMPORTANT: When installing wheel, be sure to use the  
innermost hole in axle and the wheel hub hole. To disen-  
gage drive system from the wheels (for pushing or trans-  
porting the snow thrower), remove klik pin from wheel hub  
and insert pin into the outermost hole in axle only.  
ENGINE  
See engine manual.  
CARBURETOR  
Your carburetor is not adjustable. Engine performance  
should not be affected at altitudes up to 7,000 feet (2,134  
meters). If your engine does not operate properly due to  
suspected carburetor problems, take your snow thrower to  
a qualified service center.  
KLIK PIN  
OUTER HOLE  
ENGINE SPEED  
Nevertamperwiththeenginegovernor, whichisfactoryset

the factory high speed setting can be dangerous and will  
void the warranty. If you think the engine-governed high  
speed needs adjusting, contact a qualified service center,  
which has proper equipment and experience to make any  
necessary adjustments.

STORAGE  
1. Drain the fuel tank.  
Immediately prepare your snow thrower for storage at the  
end of the season or if the unit will not be used for 30 days  
or more.  
2. Start the engine and let it run until the fuel lines and  
carburetor are empty.  
Never use engine or carburetor cleaner products in the  
fuel tank or permanent damage may occur.  
WARNING: Never store the snow  
throwerwithgasolineinthetankinside  
a building where fumes may reach an  
open flame, spark or pilot light as on a  
furnace, water heater, clothes dryer or  
gasappliance. Allowtheenginetocool  
before storing in any enclosure.  
Use fresh fuel next season.  
NOTE: Fuel stabilizer is an acceptable alternative in  
minimizing the formation of fuel gum deposits during stor-  
age. Add stabilizer to gasoline in fuel tank or storage  
container. Always follow the mix ratio found on stabilizer  
container. Run engine at least 10 minutes after adding  
stabilizer to allow the stabilizer to reach the carburetor. Do  
not drain the gas tank and carburetor if using fuel stabilizer.  
SNOW THROWER  
When snow thrower is to be stored for a period of time,  
clean it thoroughly, remove all dirt, grease, leaves, etc.  
Store in a clean, dry area.  
ENGINE OIL  
Drain oil (with engine warm) and replace with clean engine  
oil. (See “ENGINE” in the Maintenance section of this  
manual).  
1. Clean entire snow thrower (See “CLEANING” in the  
Maintenance section of this manual).  
CYLINDER  
1. Remove spark plug.  
2. Inspect and replace belts, if necessary (See “TO RE-  
PLACE BELTS” in the Service and Adjustments sec-  
tion of this manual).  
2. Pour one ounce (29 ml) of oil through spark plug hole  
into cylinder.  
3. Lubricate as shown in the Maintenance section of this  
manual.  
3. Pullrecoilstarterhandleslowlyafewtimestodistribute  
oil.  
4. Be sure that all nuts, bolts, screws, and pins are  
securely fastened. Inspect moving parts for damage,  
breakage and wear. Replace if necessary.  
4. Replace with new spark plug.  
5. Touch up all rusted or chipped paint surfaces; sand  
lightly before painting.  
OTHER  
Do not store gasoline from one season to another.  
ENGINE  
See engine manual.  
Replace your gasoline can if your can starts to rust.  
Rust and/or dirt in your gasoline will cause problems.  
If possible, store your snow thrower indoors and cover  
it to protect it from dust and dirt.  
FUEL SYSTEM  
IMPORTANT: It is important to prevent gum deposits from  
forming in essential fuel system parts such as carburetor,  
fuel hose, or tank during storage. Also, alcohol blended  
fuels (called gasohol or using ethanol or methanol) can  
attract moisture which leads to separation and formation of  
acids during storage. Acidic gas can damage the fuel  
system of an engine while in storage.  
Cover your snow thrower with a suitable protective  
cover that does not retain moisture. Do not use plastic.  
Plastic cannot breathe, which allows condensation to  
form and will cause your snow thrower to rust.  
IMPORTANT: Never cover snow thrower while engine/  
exhaust area is still warm.
