SAFETY RULES

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.

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.

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.
