IMPORTANT
BEFORE USE
• Read the Owner's Manual carefully. Be thor-
oughly 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 ap-
proved 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.
CAUTION should be exercised while using on
steep stoping 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 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
• 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 in-
struction. Do not carry passengers.
• Always wear safety glasses or eye shields
during operation or white performing an
adjustment or repair to protect eyes from for-
eign 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.
• Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at
all times.
• Exercise caution to avoid slipping or falling,
especially when operating in reverse or back-
ing 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.
SAFETY RULES
• 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.
• Never direct discharge at bystanders or allow
anyone in front of the snow thrower.
• 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.
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 un-
clogging the auger/impeller housing or dis-
charge 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).
• 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.
