RULES FOR SAFE OPERATION  
IMPORTANT  
WARNING: Always disconnect the spark plug wire and place it where it cannot make contact with  
spark plug to prevent accidental starting during: Preparation, Maintenance, or Storage of your  
snowthrower.  
Safe Operation Practices for Snowthrowers  
As Recommended By: American National Standards Institute.  
a. Use an approved fuel container.  
b. Never remove fuel tank cap or add fuel to a running en-  
gine (motor) or hot engine (motor).  
Engine Exhaust, some of its constituents, and  
certain vehicle components contain or emit  
chemicals known to the State of California to  
cause cancer and birth defects or other repro-  
ductive harm.  
c. Fill fuel tank outdoors with extreme care. Never fill fuel  
tank indoors.  
d. Replace fuel cap securely and wipe up spilled fuel.  
e. Never store fuel or snowthrower with fuel in the tank  
inside of a building where fumes may reach an open  
flame or spark.  
Battery posts, terminals and related accesso-  
ries contain lead and lead compounds, chemi-  
cals known to the State of California to cause  
cancer and birth defects or other reproductive  
harm. WASH HANDS AFTER HANDLING.  
f. Check fuel supply before each use, allowing space for  
expansion as the heat of the engine (motor) and/or sun  
can cause fuel to expand.  
5. For all units with electric starting motors use electric  
starting extension cords certified CSA/UL. Use only with  
a receptacle that has been installed in accordance with  
local inspection authorities.  
6. Adjust the snowthrower height to clear gravel or crushed  
rock surface.  
7. Never attempt to make any adjustments while the en-  
gine (motor) is running (except when specifically recom-  
mended by manufacturer).  
IMPORTANT: Safety standards require operator presence  
controls to minimize the risk of injury. Your snowthrower is  
equipped with such controls. Do not attempt to defeat the  
function of the operator presence control under any cir-  
cumstances.  
8. Let engine (motor) and snowthrower adjust to outdoor  
temperatures before starting to clear snow.  
9. Always wear safety glasses or eye shields during oper-  
ation or while performing an adjustment or repair to pro-  
tect eyes from foreign objects that may be thrown from  
the snowthrower.  
Training  
1. Read the operating and service instruction manual care-  
fully. Be thoroughly familiar with the controls and the  
proper use of the equipment. Know how to stop the unit  
and disengage the controls quickly.  
2. Never allow children to operate the equipment. Never  
allow adults to operate the equipment without proper  
instruction.  
Operation  
1. Do not operate this machine if you are taking drugs or  
other medication which can cause drowsiness or affect  
your ability to operate this machine.  
3. Keep the area of operation clear of all persons, particu-  
larly small children and pets.  
2. Do not use this machine if you are mentally or physically  
unable to operate this machine safely.  
4. Exercise caution to avoid slipping or falling especially  
when operating in reverse.  
3. Do not put hands or feet near or under rotating parts.  
Keep clear of the discharge opening at all times.  
4. Exercise extreme caution when operating on or crossing  
gravel drives, walks or roads. Stay alert for hidden haz-  
ards or traffic.  
5. After striking a foreign object, stop the engine (motor),  
remove the wire from the spark plug, thoroughly inspect  
snowthrower for any damage, and repair the damage  
before restarting and operating the snowthrower.  
6. 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.  
Preparation  
1. Thoroughly inspect the area where the equipment is to  
be used and remove all doormats, sleds, boards, wires,  
and other foreign objects.  
2. Disengage all clutches before starting the engine  
(motor).  
3. Do not operate the equipment without wearing adequate  
winter outer garments. Wear footwear that will improve  
footing on slippery surfaces.  
4. Handle fuel with care; it is highly flammable.

Maintenance And Storage  
ing position, before unclogging the auger/impeller hous-  
ing or discharge chute and when making any repairs,  
adjustments, or inspections.  
1. Check shear bolts and other bolts at frequent intervals  
for proper tightness to be sure the equipment is in safe  
working condition.  
8. When cleaning, repairing, or inspecting, make certain  
the auger/impeller and all moving parts have stopped  
and all controls are disengaged. Disconnect the spark  
plug wire and keep the wire away from the spark plug to  
prevent accidental starting.  
2. Never store the snowthrower with fuel in the tank inside  
a building where ignition sources are present such as  
hot water and space heaters, clothes dryers, and the  
like. Allow the engine (motor) to cool before storing in  
any enclosure.  
9. Take all possible precautions when leaving the snow-  
thrower unattended. Disengage the auger/ impeller, stop  
engine (motor), and remove key.  
3. Always refer to operator’s guide instructions for import-  
ant details if the snowthrower is to be stored for an ex-  
tended period.  
10.Do not run the engine (motor) indoors, except when  
starting the engine (motor) and for transporting the  
snowthrower in or out of the building. Open the outside  
doors; exhaust fumes are dangerous (containing CAR-  
BON MONOXIDE, an ODORLESS and DEADLY GAS).  
4. Maintain or replace safety and instruction labels, as  
necessary.  
5. Run the snowthrower a few minutes after throwing  
snow to prevent freeze- up of the auger/impeller.  
11. Do not clear snow across the face of slopes. Exercise  
extreme caution when changing direction on slopes. Do  
not attempt to clear steep slopes.  
12.Never operate the snowthrower without proper guards,  
plates or other safety protective devices in place.  
13.Never operate the snowthrower near enclosures, auto-  
mobiles, window wells, drop- offs, and the like without  
proper adjustment of the snow discharge angle. Keep  
children and pets away.  
WARNING: Avoid  
injury from rotating  
auger- keep hands,  
feet, and clothing  
away.  
14.Do not overload the machine capacity by attempting to  
clear snow at too fast a rate.  
15.Never operate the machine at high transport speeds on  
slippery surfaces. Look behind and use care when back-  
ing up.  
16.Never direct discharge at bystanders or allow anyone in  
front of the unit.  
17.Disengage power to the collector/impeller when snow-  
thrower is transported or not in use.  
WARNING: Do not  
use hands to un-  
clog discharge  
chute.  
18.Use only attachments and accessories approved by the  
manufacturer of the snowthrower (such as tire chains,  
electric start kits, ect.).  
19.Never operate the snowthrower without good visibility or  
light. Always be sure of your footing and keep a firm  
hold on the handles. Walk;never run.  
• Stop engine/motor before removing debris.  
• Do not walk in front of running machine.  
• Do not discharge at bystanders.

OPERATION  
2. Check to make sure that spark plug is tightened securely  
BEFORE STARTING ENGINE  
Check the oil  
into engine and spark plug wire is attached to spark plug.  
If torque wrench is available, torque plug to 18-23 ft-lbs.  
NOTE: The engine was shipped from the factory filled  
with oil. Check the level of the oil. Add oil as needed.  
WARNING: Gasoline is flammable. Always use  
caution when handling or storing gasoline. Do  
not add gasoline to the fuel tank while snow-  
thrower is running, hot, or when snowthrower is in an  
enclosed area. Keep away from open flame, electrical  
sparks and DO NOT SMOKE while filling the fuel tank.  
Never fill the fuel tank completely; but fill the fuel tank  
to within 1/4-1/2 inch (6.5-12.5 mm) from the top to pro-  
vide space for the expansion of the fuel. Always fill fuel  
tank outdoors and use a funnel or spout to prevent spil-  
ling. Make sure to wipe up any spilled fuel before start-  
ing the engine.  
Store gasoline in a clean, approved container, and keep  
the cap in place on the container. Keep gasoline in a  
cool well ventilated place; never in the house. Never  
buy more than a 30 day supply of gasoline to assure  
volatility. Gasoline Is intended to be used as a fuel for  
internal combustion engines; therefore, do not use  
gasoline for any other purpose. Since many children  
like the smell of gasoline, keep it out of their reach be-  
cause the fumes are dangerous to inhale, as well as be-  
ing explosive.  
1. Make sure the unit is level.  
2. Remove the oil fill cap/dipstick. Check the oil.  
NOTE: Do not check the level of the oil while the  
engine runs.  
3. If necessary, add oil until the oil reaches the FULL mark  
on the oil fill/cap dipstick (see Figure 17). Do not add too  
much oil.  
NOTE: For extreme cold operating conditions of 0_F  
(-18 _ C) and below, use a synthetic 0W30 motor oil for  
easier starting.  
NOTE: S.A.E. 5W30 motor oil may be used to make  
starting easier in areas where the temperature is 20_ F.

6. On gravel or crushed rock surfaces, the skids should be  
set at 1-1/4 inch (32 mm) below the scraper bar (see To  
Adjust Skid Height, in the MAINTENANCE section in this  
manual). Rocks and gravel must not be picked up and  
thrown by the machine.  
OPERATING TIPS  
1. For optimum snowthrower efficiency, adjust ground  
speed, not the throttle. REMEMBER - if the wheels slip,  
forward speed will be reduced. The engine is designed  
to deliver optimum performance at full throttle and must  
be run at this power setting at all times.  
7. After the snowblowing job has been completed, allow the  
engine to idle for a few minutes, to melt snow and ice ac-  
cumulated on the engine.  
2. Most efficient snowblowing is accomplished when snow  
is removed immediately after it falls.  
8. Remove ice and snow accumulation from the entire  
snowthrower to prevent obstructions and possible dam-  
age when snowthrower is subsequently operated.  
3. For complete snow removal, slightly overlap each swath  
previously taken.  
4. Snow should be discharged downwind whenever pos-  
sible.  
9. Before starting snowthrower, always inspect augers and  
impeller for ice accumulation and/or debris, which could  
result in snowthrower damage.  
5. For normal usage, set the skids one-eighth inch (3 mm)  
below the scraper bar. For extremely hard-packed snow  
surfaces, the skids may be adjusted upward to insure  
cleaning efficiency.  
10. Check oil level before every start. fill to “SAFE” indication  
prior to operating snowthrower.

fore making any repairs or adjustments.  
1. Place a block (equal to height from ground desired) un-  
der scraper bar near but not under skid.  
AUGER HOUSING HEIGHT ADJUSTMENT  
TO ADJUST SCRAPER BAR  
After considerable use, the metal scraper bar will have a  
definite wear pattern. The scraper bar in conjunction with the  
skids should always be adjusted to allow one-eighth of an  
inch (3 mm) between the scraper bar and the sidewalk or  
area to be cleaned.  
2. Loosen skid mounting nuts (Figure 26) and push the skid  
down until it touches the ground. Retighten mounting  
nuts.  
3. Set skid on other side at same height.  
NOTE: Make sure that snowthrower is set at same height  
on both sides.  
To adjust the scraper bar, proceed as follows:  
1. Position the snowthrower on a level surface.  
WARNING: Be certain to maintain proper  
ground clearance for your particular area to be  
cleared. Objects such as gravel, rocks or other  
debris, if struck by the impeller, may be thrown with  
sufficient force to cause personal injury, property dam-  
age or damage to the snowthrower.  
2. Loosen the carriage bolts and nuts securing the scraper  
bar to the auger housing.  
3. Adjust the scraper bar to the proper position. Tighten the  
carriage bolts and nuts, insuring that the scraper bar is  
parallel with the working surface.  
4. For extended operation, the scraper bar may be re-  
versed. If the scraper bar must be replaced because of  
wear, remove the carriage bolts and nuts and install a  
new scraper bar.  
Height Adjust Skid  
Skid Mounting Nuts  
TO ADJUST SKID HEIGHT  
This snowthrower is equipped with two height adjust skids,  
secured to the outside of the auger housing. These elevate  
the front of the snowthrower.  
When removing snow from a hard surface area such as a  
paved driveway or walk, adjust the skids up to bring the front  
of the snowthrower down.  
When removing snow from rock or uneven construction,  
raise the front of the snowthrower by moving the skids down.  
This will help to prevent rocks and other debris from being  
picked up and thrown by the augers.

AUGER SHEAR BOLT REPLACEMENT  
The augers are secured to the auger shaft with special bolts  
that are designed to break if an object becomes lodged in the  
auger housing. Use of a harder bolt will reduce the protection  
provided by the shear bolt. To replace a broken shear bolt,  
proceed as follows:  
Shear Pin  
WARNING: To insure safety and performance  
levels, only original replacement shear bolts  
should be used.  
Spacer  
1. Move throttle to STOP, disengage all controls, discon-  
nect the spark plug lead wire, and insure all moving parts  
have stopped.

the tank, indoors or in a poor ventilated enclo-  
sure where fuel fumes could reach an open  
flame, spark or pilot light as on a furnace, water heater,  
clothes dryer, etc.  
Handle gasoline carefully. It is highly flammable and  
careless use could result In serious fire damage to your  
person and /or property.  
6. Insure that all nuts, bolts, and screws are securely fas-  
tened. Inspect all visible moving parts for damage,  
breakage, and wear. Replace if necessary.

from open flame.  
8. Cover the bare metal parts of the snowthrower housing  
auger, and the impeller with rust preventative.  
If the snowthrower is to be stored for thirty (30) days or more  
at the end of the snow season, the following steps are  
recommended to prepare your snowthrower for storage.  
9. If possible, store your snowthrower indoors and cover it  
to give protection from dust and dirt.  
NOTE: Gasoline must be removed or treated to prevent  
gum deposits from forming in the tank, filter, hose, and  
carburetor during storage.  
10. On models with folding handles, loosen the knobs that  
secure the upper handle. Rotate the upper handle back.  
11. If the machine must be stored outdoors, block up the s-  
nowthrower and insure the entire machine is off the  
ground. Cover the snowthrower with a heavy tarpaulin.  
1. To remove gasoline, run engine until tank is empty and  
engine stops.  
If you do not want to remove the gasoline, add fuel stabilizer  
to any gasoline left in the tank to minimize gum deposits and  
acids. If the tank is almost empty, mix stabilizer with fresh  
gasoline in a separate container and add some to the tank.  
ALWAYS FOLLOW INSTRUCTIONS ON STABILIZER  
CONTAINER. THEN RUN ENGINE AT LEAST 10 MINUTES  
AFTER STABILIZER IS ADDED TO ALLOW MIXTURE TO  
REACH CARBURETOR. STORE SNOWTHROWER IN  
SAFE PLACE.  
REMOVING THE SNOWTHROWER FROM  
STORAGE  
When removing the snowthrower from storage, follow the  
steps below.  
1. Put the upper handle in the operating position, tighten the  
knobs that secure the upper handle.  
2. You can help keep your engine (4-cycles only) in good  
operating condition by changing oil before storage.  
2. Fill the fuel tank with a fresh fuel.  
3. Check the spark plug. Make sure the gap is correct. If the  
spark plug is worn or damaged, replace before using.  
3. Lubricating the piston/cylinder area. This can be done by  
first removing the spark plug and squirting clean engine  
oil into the spark plug hole. Then cover the spark plug  
hole with a rag to absorb oil spray. Next, rotate the engine  
by pulling the starter two or three times. Finally, reinstall  
spark plug and attach spark plug wire.  
4. Make sure all fasteners are tight.
