qualified repair person using only identical
replacement parts. This will ensure that the safety of
the Snow Thrower is maintained.

Safe handling of gasoline

To avoid personal injury or property damage use
extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are
explosive. Serious personal injury can occur
when gasoline is spilled on yourself or your
clothes which can ignite, wash your skin and
change clothes immediately.

• Use only an approved gasoline container.

• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.

• Never fuel machine indoors.

• Never remove gas cap or add fuel while the engine
is hot or running.

• Allow engine to cool at least two minutes before
refueling.

• Never over fill fuel tank.Fill fuel to no more than 112
inch below bottom of filler neck to provide space for
fuel expansion.

• Replace gasoline cap and tighten securely.

• If gasoline is spilled, wipe it off the engine and
equipment. Move machine to another area. Wait 5
minutes before starting the engine.

• Never store the machine or fuel container inside
where there is an open flame, spark or pilot light
(e.g. furnace, water heats, space heater, clothes
dryer etc.).

• Allow machine to cool at least 5 minutes before
storing.

• Never fill containers inside a vehicle or on a truck or
trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle
before filling.

• If possible, remove gas-powered equipment from
the truck or trailer and refuel it on the ground.

• If this is not possible, then refuel such equipment on
a trailer with a portable container, rather than from a
gasoline dispenser nozzle.

• Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. Do not use a nozzle lock open device.

Operation

• Do not put hands or feet near rotating parts, in the
auger impeller housing or chute assembly. Contact
with the rotating parts can amputate hands and feet.

• The auger impeller control lever is a safety device.
Never bypass its operation. Doing so makes the
machine unsafe and may cause personal injury.

• The control levers must operate easily in both
directions and automatically return to the
disengaged position when released.

• Never operate with a missing or damaged chute
assembly. Keep all safety devices in place and
working.

• Never run an engine indoors or in a poorly
ventilated area. Engine exhaust contains carbon
monoxide, an odorless and deadly gas,

• Do not operate machine while under the influence of
alcohol or drugs.

• Muffler and engine become hot and can cause a
bum. Do not touch. Keep children away.

• Exercise extreme caution when operating on or
crossing gravel surfaces. Stay alert for hidden
hazards or traffic.

• Exercise caution when changing direction and while
operating on slopes.

• Plan your snow-throwing pattern to avoid discharge
towards windows, walls, cars etc. Thus, avoiding
possible property damage or personal injury caused
by a ricochet.

• Never direct discharge at children, bystanders and
pets or allow anyone in front of the machine.

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

• Never operate this machine without good visibility or
light. Always be sure of your footing and keep a firm
hold on the handles. Walk, never run.

• Disengage power to the auger impeller when
transporting or not in use.

• Never operate machine at high transport speeds on
slippery surfaces. Look down and behind and use
care when backing up.

3

• If the machine should start to vibrate abnormally,
stop the engine, disconnect the spark plug wire and
ground it against the engine.Inspect thoroughly for
damage. Repair any damage before starting and
operating.

• Disengage all control levers and stop engine before
you leave the operating (behind the handles).

• Wait until the auger /impeller comes to a complete
stop before unclogging the chute assembly, making
any adjustments, or inspections.

• Never put your hand in the discharge or collector
openings. Always use the dean-out tool provided to
unclog the discharge opening. Do not unclog chute
assembly while engine is running. Shut off engine
and remain behind handles until all moving parts
have stopped before unclogging.

• Use only attachments and accessories approved by
the manufacturer (e.g. wheel weights, tire chains,
cabs etc.).

• When staring engine, pull cord slowly until
resistance is felt, then pull rapidly, Rapid retraction
of starter cord (kickback) will pull hand and arm
toward engine faster than you can let go. Broken
bones, fractures, bruises or sprains could result.

• If situations occur which are not covered in this
manual, use care and good judgment contact
customer support for assistance.

Maintenance & Storage

• Never tamper with safety devices. Check their
proper operation regularly. Refer to the
maintenance and adjustment sections of manual.

• Before cleaning, repairing, or inspecting machine
disengage all control levers and stop the engine.

• Wait until the auger impeller come to a complete
stop. Disconnect the spark plug wire and ground
against the engine to prevent unintended starting.

• Check bolts and screws for proper tightness at
frequent intervals to keep the machine in safe
working condition. Also, visually inspect machine for
any damage.

• Do not change the engine governor setting or over­speed the engine. The governor controls the
maximum safe operating speed of the engine.

• Snow thrower shave plates and skid shoes are
subject to wear and damage. For your safety
protection, frequently check all components and
replace with original equipment manufacturers
(OEM) parts only. Use of parts which do not meet
the original equipment specifications may lead to
improper performance and compromise safety.

• Check control levels periodically to verify they
engage and disengage properly and adjust, if
necessary. Refer to the adjustment section in this
operator's manual for instructions.

• Maintain or replace safety and instruction labels, as
necessary.

• Observe proper disposal laws and regulations for
gas, oil, etc. to protect the environment.

• Prior to storing, run machine a few minutes to clear
snow from machine and prevent freeze up of auger
impeller.

• Never store the machine or fuel container inside
where there is an open flame,spark or pilot light
such as water heater, furnace, clothes dryer etc.

• Always refer to the operator's manual for proper
instructions on off-season storage.

• Check fuel line, tank, cap and fittings frequently for
cracks or leaks. Replace if necessary.

• Do not crank engine with spark plug removed.

• Have the machine inspected annually by an
authorized service dealer to ensure that all
mechanical and safety systems are working
properly and do not worn excessively. Failure to do
so can result in accidents, injuries or death.

Do Not Modify The Engine

To avoid serious injury or death, do not modify
engine in any way. Tampering with the governor

setting can lead to a runaway engine and cause it
to operate at unsafe speeds. Never tamper with
factory setting of engine governor.
