To avoid personal injury or property damage use extreme care 8.
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.a.

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

When practical, remove gas-powered equipment from c.
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 d.
tank or container opening at all times, until refueling is
complete. Do not use a nozzle lock-open device.

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

Never fuel machine indoors. f.

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

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

Never over fill fuel tank. Fill tank to no more than ½ inch i.
below bottom of filler neck to provide space for fuel
expansion.

Replace gasoline cap and tighten securely.j.

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

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

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

Operation

Do not put hands or feet near rotating parts, in the auger/1.
impeller housing or discharge chute. Contact with the
rotating parts can amputate hands and feet.

Never operate with a missing or damaged discharge chute. 2.
Keep all safety devices in place and working.

When cleaning, repairing or inspecting the snow thrower, 3.
make certain the collector/impeller and all moving
parts have stopped. Disconnect the spark plug wire and
keep the wire away from the plug to prevent someone
from accidentally starting the machine. 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.

Do not operate machine while under the influence of 4.
alcohol or drugs.

Muffler and engine become hot and can cause a burn. Do 5.
not touch.

Exercise extreme caution when operating on or crossing 6.
gravel surfaces. Stay alert for hidden hazards or traffic. Do
not carry passengers.

Exercise caution when changing direction and while 7.
operating on slopes.

Do not clear snow across the face of slopes; go up and 8.
down. Exercise extreme caution when operating on slopes.
Do not attempt to clear steep slopes.

Plan your snow throwing pattern to avoid discharge 9.

towards windows, walls, cars etc. To avoid property
damage or personal injury caused by a ricochet.

Never direct discharge at children, bystanders and pets or 10.
allow anyone in front of the machine.

Do not overload machine capacity by attempting to clear 11.
snow at too fast of a rate.

Never operate this machine without good visibility or light.12.

Disengage power to the auger/impeller when transporting 13.
or not in use.

Never operate machine at high transport speeds on 14.
slippery surfaces. Look down and behind and use care
when in reverse.

If the machine should start to vibrate abnormally, stop 15.
the engine, disengage the power take-off, lower the
attachment and set the parking brake. Inspect thoroughly
for damage. Repair any damage before starting and
operating.

After striking a foreign object, stop the engine (motor), 16.
remove the wire from the spark plug, thoroughly inspect
the snow thrower for any damage, and repair the damage
before restarting and operating the snow thrower.

Disengage the power take-off, lower attachment, set 17.
the parking brake and stop engine before you leave the
operating position. Wait until the auger/impeller comes to
a complete stop before unclogging the discharge chute,
making any adjustments, or inspections.

Clearing A Clogged Discharge Chute

Hand contact with the rotating impeller inside the discharge

chute is the most common cause of injury associated with snow
throwers. Never use your hand to clean out the discharge chute.

To clear the chute:

SHUT THE ENGINE OFF!1.

Wait 10 seconds to be sure the impeller blades have 2.
stopped rotating.

Always use a clean-out tool, not your hands.3.

Maintenance And Storage

Never tamper with safety devices. Check their proper 1.
operation regularly.

Disengage power take-off, lower the attachment, set the 2.
parking brake, stop engine and remove key to prevent
unintended starting. Wait until the auger/impeller comes to a
complete stop before cleaning, repairing, or inspecting.

Check bolts, and screws for proper tightness at frequent 3.
intervals to keep the machine in safe working condition. Also,
visually inspect machine for any damage.

Do not change the engine governor setting or over-speed the 4.
engine. The governor controls the maximum safe operating
speed of the engine.

Snow thrower shave plates and skid shoes are subject to 5.
wear and damage. For your safety protection, frequently
check all components and replace with original equipment

manufacturer’s (O.E.M.) parts only. “Use of parts which do

not meet the original equipment specifications may lead to

improper performance and compromise safety!”

Check clutch controls periodically to verify they engage and 6.

disengage properly and adjust, if necessary. Refer to the PTO
and safety interlock system in your tractor’s operator’s manual

for instructions.

Maintain or replace safety and instruction labels, as necessary.7.

Observe proper disposal laws and regulations for gas, oil, etc. 8.
to protect the environment.

Prior to storing, run machine a few minutes to clear snow from 9.

machine and prevent freeze up of auger/impeller.
