SAFETY RULES
BEFORE USE
Read the Owner’s Manual carefully. Be thoroughly
familiar with the controls and the proper use of the snow
thrower. Know how to stop the snow thrower and
disengage the controls quickly.
Do not operate the snow thrower without wearing
adequate winter outer garments. Wear footwear that will
improve footing on slippery surfaces.
Keep the area of operation clear of all persons, particularly
small children, and pets.
Thoroughly inspect the area where the snow thrower is
to be used and remove all doormats, sleds, boards,
wires, and other foreign objects.
Use extension cords and receptacles as specified by the
manufacturer for all snow throwers with electric drive
motors or with factory-installed or optional starting
motors.
Use only attachments and accessories approved by the
manufacturer of the snow thrower (such as electric
starter kits, etc.).
Never operate the snow thrower without good visibility
or light. Always be sure of your footing, and keep a firm
hold on the handles. Walk; never run.
This snow thrower is for use on sidewalks, driveways,
and other ground level surfaces. Do not attempt to
clear on steep sloping surfaces. DO NOT USE
SNOW THROWER ON SURFACES ABOVE GROUND
LEVEL such as roofs of residences, garages, porches
or other such structures or buildings.
Check all bolts at frequent intervals for proper tightness
to be sure the snow thrower is in safe working condition.
Disengage clutch and shift into neutral before starting
the engine.
Let engine and snow thrower adjust to outdoor
temperatures before starting to clear snow.
FUEL SAFETY
Handle fuel with care; it is highly flammable.
Use an approved fuel container.
Check fuel supply before each use, allowing space for
expansion as the heat of the engine and/or sun can
cause fuel to expand.
Fill fuel tank outdoors with extreme care. Never fill fuel
tank indoors.
Replace fuel tank cap securely and wipe up spilled fuel.
Never remove fuel tank cap or add fuel to a running
engine or hot engine.
Never store fuel or snow thrower with fuel in the tank
inside a building where fumes may reach an open flame
or spark.
OPERATING SAFETY
Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
Never operate the snow thrower without proper guards,
plates or other safety protective devices in place.
Never allow children or young teenagers to operate the
snow thrower and keep them away while it is operating.
never allow adults to operate the snow thrower without
proper instruction.
Always wear safety glasses or eye shields during operation
or while performing an adjustment or repair to protect eyes
from foreign objects that may be thrown from the snow
thrower.
Exercise extreme caution when operating on or crossing
gravel drives, walks, or roads. Stay alert for hidden hazards
or traffic.
Exercise caution to avoid slipping or falling, especially when
operating in reverse or backing up.
Do not clear snow across the face of slopes. Exercise
caution when changing direction on slopes. Do not attempt
to clear steep slopes.
Never operate the snow thrower without proper guards,
plates or other safety protective devices in place.
Never operate the snow thrower near glass enclosures,
automobiles, window wells, drop-offs, and the like without
proper adjustment of the snow discharge angle. Keep
children and pets away.
Never operate the snow thrower at high transport speeds on
slippery surfaces. Look behind and use care when backing.
Do not run the engine indoors, except when starting the
engine and for transporting the snow thrower in or out of the
building. Open the outside doors; exhaust fumes are
dangerous (containing CARBON MONOXIDE, an
ODORLESS and DEADLY GAS).
Take all possible precautions when leaving the snow thrower
unattended. Disengage the auger/impeller, stop engine,
and remove key.
Do not overload the machine capacity by attempting to clear
snow at too fast a rate.
Never direct discharge at bystanders or allow anyone in
front of the unit.
ALWAYS DISCONNECT SPARK PLUG WIRE AND PLACE WIRE WHERE IT
CANNOT CONTACT SPARK PLUG TO PREVENT ACCIDENTAL STARTING
WHEN SETTING-UP, TRANSPORTING, ADJUSTING OR MAKING REPAIRS.
IMPORTANT
SAFETY STANDARDS REQUIRE OPERATOR PRESENCE CONTROLS TO MINIMIZE THE RISK OF INJURY.
YOUR SNOW THROWER IS EQUIPPED WITH SUCH CONTROLS. DO NOT ATTEMPT TO DEFEAT THE
FUNCTION OF THE OPERATOR PRESENCE CONTROL UNDER ANY CIRCUMSTANCES.

LOOK FOR THIS SYMBOL TO POINT OUT IMPORTANT SAFETY PRECAUTIONS. IT MEANS--
ATTENTION!!! BECOME ALERT!!! YOUR SAFETY IS INVOLVED.
SAFETY RULES
SAFE STORAGE
Always refer to Owner’s Manual instructions for important
details if the snow thrower is to be stored for an extended
period.
Disengage power to the auger/impeller when snow thrower
is transported or not in use.
Never store the snow thrower with fuel in the fuel tank
inside a building where ignition sources are present such
as hot water and space heaters, clothes dryers, and the
like. Allow the engine to cool before storing in any
enclosure.
REPAIR/ADJUSTMENTS SAFETY
After striking a foreign object, stop the engine and remove
the wire from the spark plug, or disconnect the cord from
electric motor. Thoroughly inspect the snow thrower for
any damage, and repair the damage before restarting and
operating the snow thrower.
If the snow thrower should start to vibrate abnormally,
stop the engine (or electric motor) and check immediately
for the cause. Vibration is generally a warning of trouble.
STOP THE ENGINE (OR ELECTRIC MOTOR)
WHENEVER YOU LEAVE THE OPERATING POSITION,
BEFORE UNCLOGGING THE AUGER/IMPELLER
HOUSING OR DISCHARGE GUIDE, AND WHEN
MAKING ANY REPAIRS, ADJUSTMENTS, OR
INSPECTIONS. REMOVE WIRE FROM SPARK PLUG
OR DISCONNECT CORD FROM ELECTRIC MOTOR.
When cleaning, repairing, or inspecting, make certain the
auger/impeller and all moving parts have stopped.
Disconnect the spark plug wire and keep the wire away
from the plug to prevent accidental starting.
Never attempt to make any adjustments while the engine
is running (except when specifically recommended in
this manual or the engine manual).
Maintain or replace safety and instruction labels, as
necessary.
Run the snow thrower a few minutes after throwing snow
to prevent freeze-up of the auger/impeller.

OPERATION
HOW TO USE YOUR SNOW
THROWER
TO CONTROL SNOW DISCHARGE
Turn the crank assembly to set the direction of the
snow throwing.
Loosen the wing knob on the chute deflector and
move the deflector to set the distance. Move the
deflector UP for more distance, DOWN for less
distance. Then tighten the wing knob (See III 10).
TO STOP YOUR SNOW THROWER
To stop throwing snow, release the auger clutch
lever (See III 12).
To stop the wheels, release the traction clutch lever.
To stop the engine, push the throttle control lever to
off and pull out the ignition key (See III 11).
TO MOVE FORWARD AND
BACKWARD
To shift, release the traction clutch lever and move
the speed shifter lever to the speed you desire.
Ground speed is determined by snow conditions.
Select the speed you desire by moving the speed
shifter lever into the appropriate colored area on the
control panel.
Red - Wet, Heavy, Slushy, Extra Deep
Amber - Moderate
White - Very Light
Green - Transport only
Engage the traction clutch lever (See III 12, left
hand). As the snow thrower starts to move, main-
tain a firm hold on the handles, and guide the snow
thrower along the clearing path. Do not attempt to
push the snow thrower.
This unit is equipped with a single hand control
feature. This will allow the operator to hold both
engaged levers with one hand thus freeing other
hand.
To activate single hand control feature:
Push down on both levers to engaged positon.
Once engaged either hand may be removed from
levers. Both levers will remain engaged as long as
one is held down.
To disengage single hand control operation release
lever which is being held down and both levers will
automatically disengage.
The operation of any snow thrower can result in foreign objects being thrown into the
eyes, which can result in severe eye damage. Always wear safety glasses or eye
shields while operating the snow thrower.
We recommend standard safety glasses or Wide Vision Safety Mask for over your
glasses.
To move the snow thrower backward, move the
speed shifter lever into first or second reverse and
engage the traction clutch lever (left hand).
IMPORTANT: DO NOT MOVE THE SPEED SHIFT
LEVER WHILE THE TRACTION
LEVER IS DOWN.
TO THROW SNOW
Push down the auger clutch lever (See III 12, right
hand).
Release to stop throwing snow.
TO USE WHEEL LOCKOUT PIN
The left hand wheel is secured to the axle with a klick
pin (See III 13). This unit was shipped with this klick
pin in the locked (through wheel hole) position.
For ease of maneuverability in light snow conditions,
disconnect the klick pin from the wheel locked posi-
tion and push into the single wheel drive (unlocked
axle hole only) position (See III 14).
Make sure that the klick pin is in the single wheel
drive position of the axle only and not through the
locked position.
BEFORE STARTING THE ENGINE
If the snow thrower must be moved without the aid of
the engine, it is easier to pull the snow thrower by the
handles rather than pushing.
Before you service or start the engine, familiarize
yourself with the snow thrower. Be sure you under-
stand the function and location of all controls.
NOTE: Check tension of clutch cables before starting the
engine. (See To Adjust The Control Cables paragraph
in the Service & Adjustments section of this manual).
Be sure that all fasteners are tight.
Make sure the height adjust skids are properly ad-
justed (See To Adjust Skid Height paragraph in
the Service & Adjustments section of this manual).
Check tire pressure (14 to 17 pounds). Do not
exceed maximum amount of pressure.
FILL OIL:
The engine on this snow thrower was shipped without
oil. 5W30 oil is included with this unit and must be added
to the engine before operating. Remove the oil fill cap/
dipstick and fill the crank case to "FULL" line on dipstick
(See III.15) with S.A.E. 5W-30 motor oil (or equivalent).
Do not overfill. Tighten the fill cap/dipstick securely each
time you check the oil level.
20
OPERATION
FILL GAS:
Fill the fuel tank with clean, fresh, unleaded grade auto-
motive gasoline. Be sure that the container you pour the
gasoline from is clean and free from rust or other foreign
particles. Never use gasoline that may be stale from long
periods of storage in the container.
NOTE: S.A.E. 5W-30 motor oil may be used to make
starting easier in areas where temperature is consis-
tently 20° F. or lower.
WARNING: Experience indicates that alcohol blended
fuels (called gasohol or those using ethanol or metha-
nol) 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.
To avoid engine problems, the fuel system should be
emptied before storage for 30 days or longer. Start the
engine and let it run until the fuel lines and carburetor are
empty. Use the carburetor bowl drain to empty residual
gasoline from the float chamber (III 33). Use fresh fuel
next season (See Storage section in this manual for
additional information).
TO STOP ENGINE
To stop engine, move the throttle control lever to
"STOP" position and remove key. Keep the key in a
safe place. The engine will not start without the key.
TO START ENGINE (Electric Starter)
Be sure that the engine has sufficient oil. The snow
thrower engine is equipped with a 120 volt A.C. electric
starter and recoil starter. Before starting the engine, be
certain that you have read the following information:
COLD START (See III.9)
Be sure the auger drive and traction drive levers are
in the disengaged "RELEASED" position.
Move the throttle control up to "FAST" position.
Push the key into the ignition slot. Be sure it snaps
into place. Do not turn the key. Remove the plastic
bag and extra key.
Rotate the choke knob to "FULL" choke position.
Connect the power cord to the switch box on the
engine.
Plug the other end of the power cord into a three
hole, grounded 120 volt A.C. receptacle.
Press the primer button two or three times while
keeping your finger over the vent hole on the primer
button. Additional priming may be necessary for the
first start if the temperature is below 15° F.
Push down on the starter button until the engine
starts. Do not crank for more than 10 seconds at a
time. This electric starter is thermally protected. If
overheated it will stop automatically and can be
restarted only when it has cooled to a safe tempera-
ture (a wait of about 5 to 10 minutes is required).
THIS STARTER IS EQUIPPED WITH A
THREE-WIRE POWER CORD AND PLUG
AND IS DESIGNED TO OPERATE ON 120
VOLT AC HOUSEHOLD CURRENT.
IT MUST BE PROPERLY GROUNDED AT
ALL TIMES TO AVOID THE POSSIBILITY
OF ELECTRICAL SHOCK WHICH MAY
BE INJURIOUS TO OPERATOR.
FOLLOW ALL INSTRUCTIONS CARE-
FULLY AS SET FORTH IN THE “TO
START ENGINE” SECTION. DETERMINE
THAT YOUR HOUSE WIRING IS A THREE-
WIRE GROUNDED SYSTEM.
ASK A LICENSED ELECTRICIAN IF YOU
ARE NOT SURE.
IF YOUR HOUSE WIRE SYSTEM IS NOT
A THREE-WIRE SYSTEM, DO NOT USE
THIS ELECTRIC STARTER UNDER ANY
CONDITIONS.
IF YOUR SYSTEM IS GROUNDED AND A
THREE-HOLE RECEPTACLE IS NOT
AVAILABLE AT THE POINT YOUR
STARTER WILL NORMALLY BE USED,
ONE SHOULD BE INSTALLED BY A LI-
CENSED ELECTRICIAN.
WHEN CONNECTING 120 VOLT AC
“POWER CORD,” ALWAYS CONNECT
THE CORD TO THE “SWITCH BOX” ON
THE ENGINE FIRST, THEN PLUG THE
OTHER END INTO THE THREE-HOLE
GROUNDED RECEPTACLE.
WHEN DISCONNECTING “POWER
CORD,” ALWAYS UNPLUG THE END IN
THE THREE-HOLE GROUNDED RECEP-
TACLE FIRST.
When the engine starts, release the starter button
and slowly rotate the choke to "OFF" position. If the
engine falters, rotate the choke to "FULL" and then
gradually to "OFF".
Disconnect the power cord from the receptacle first
and then from switch box on engine.
NOTE: Allow the engine to warm up for a few minutes
because the engine will not develop full power until it
reaches operating temperature.
Run the engine at or near the top speed when
throwing snow.
WARM START
If restarting a warm engine after a short shutdown, leave
choke at "OFF" and do not push the primer button.
