2. PREPARATION

• Thoroughly inspect the area where the equipment
is to be used and remove all door mats, sleds,
boards, wires and other foreign objects.

• Disengage all clutches and shift into neutral before
starting engine.

• Do not operate equipment without wearing
adequate winter outer garments. Do not wear
jewelry, long scarfs or other loose clothing which
could become entangled in moving parts. Wear
footwear which will improve footing on slippery
surfaces.

• Before working with gasoline, extinguish all
cigarettes and other sources of ignition. Check the
fuel before starting the engine. Gasoline is an
extremely flammable fuel. Do not fill the gasoline
tank indoors, while the engine is running, or until
engine has been allowed to cool at least two
minutes. Replace gasoline cap securely and wipe
off any spilled gasoline before starting the engine
as it may cause a fire or explosion.

• Use a grounded three wire plug-in for all units with
electric drive motors or electric starting motors.

• Adjust collector housing height to clear gravel or
crushed rock surface.

• Never attempt to make any adjustments while
engine is running (except where specifically
recommended by manufact urer).

• Let engine and machine adjust to outdoor
temperature before starting to clear snow.

• 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 machine in any direction.

3. OPERATION

• Do not put hands or feet near or under rotating
parts. Keep clear of discharge opening and auger
at all times.

• Exercise extreme caution when operating on or
crossing gravel drives, walks, or roads. Stay alert
for hidden hazards or traffic. Do not carry
passengers.

• After striking a foreign object, stop the engine,
remove wire from spark plug, and thoroughly
inspect the snow thrower for any damage. Repair
the damage before restarting and operating the
snow thrower.

3

• If the snow thrower should start to vibrate
abnormally, stop the engine and check immediately
for the cause. Vibration is generally a warning of
trouble.

• Stop engine whenever you leave the operating
position, before unclogging the collector/impeller
housing or discharge guide, and making any
repairs, adjustments, or inspections. Never place
your hand in the discharge or collector openings.
Use a stick or wooden broom handle to unclog the
discharge opening.

• Take all possible precautions when leaving the unit
unattended. Disengage the collector/impeller, stop
the engine, and remove the key.

• When cleaning, repairing, or inspecting, make
certain collector/impeller and all moving parts have
stopped. Disconnect spark plug wire and keep
away from plug to prevent accidental starting.

• Do not run engine indoors, except when starting
engine and transporting snow thrower in or out of
building. Open doors. Exhaust fumes are
dangerous.

• Do not clear snow across the face of slopes.
Exercise ext reme caution when ch anging direction
on slopes. Do not attempt to clear steep slopes.

• Never operate snow thrower without guards, plates,
or other safety protection devices in place.

• Never operate snow thrower near glass enclosure,
automobiles, window wells, drop off, etc., without
proper adjustments of snow thrower discharge
angle. Keep children and pets away .

• Do not overload machine capacity by attempting to
clear snow at too fast a rate.

• Never operate the machine 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 unit.

• Disengage power to collector/impeller when
transporting or not in use.

• Use only attachments and accessories approved
by the manufacturer of snow thrower (such as
wheel weights, counter weights, cabs, 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.

• Muffler and engine become hot and can cause a
burn. Do not touch.

4. MAINTENANCE AND STORAGE

• Check shear bolts, engine mounting bolts, etc., at
frequent intervals for proper tightness to be sure
equipment is in safe working condition.

• Never store the machine 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 engine to cool
before storing in any enclosure.

• Always refer to operator's manual instructions for
important details if snow thrower is to be stored for
an extended period.

• Run machine a few minutes after throwing snow to
prevent freeze up of collector/impeller.

• Check clutch controls periodically to verify they
engage and disengage properly and readjust if
necessary. Refer to operator's manual for
adjustment instructions .
