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.

Extinguish all cigarettes, cigars, pipes and other

b.

sources of ignition.

Never fuel machine indoors.

c.

Never remove gas cap or add fuel while the engine is

d.

hot or running.

Allow engine to cool at least two minutes before

e.

refueling.

Never over fill fuel tank. Fill tank to no more than ½

f.

inch below bottom of filler neck to provide space for
fuel expansion.

Replace gasoline cap and tighten securely.

g.

If gasoline is spilled, wipe it off the engine and

h.

equipment. Move machine to another area. Wait 5
minutes before starting the engine.

Never store the machine or fuel container inside

i.

(e.g. furnace, water heater, space heater, clothes
dryer etc.).

Allow machine to cool at least 5 minutes before

j.

storing.

Never fill containers inside a vehicle or on a truck

k.

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

l.

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

m.

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/

1.
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

2.
bypass its operation. Doing so makes the machine unsafe
and may cause personal injury.

The control levers must operate easily in both directions

3.
and automatically return to the disengaged position when
released.

Never operate with a missing or damaged chute assembly.

4.
Keep all safety devices in place and working.

Never run an engine indoors or in a poorly ventilated area.

5.
Engine exhaust contains carbon monoxide, an odorless
and deadly gas.

Do not operate machine while under the influence of

6.
alcohol or drugs.

Muffler and engine become hot and can cause a burn. Do

7.
not touch. Keep children away.

Exercise extreme caution when operating on or crossing

8.
gravel surfaces. Stay alert for hidden hazards or traffic.

Exercise caution when changing direction and while

9.
operating on slopes.

Plan your snow-throwing pattern to avoid discharge

10.
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

11.
allow anyone in front of the machine.

Do not overload machine capacity by attempting to clear

12.
snow at too fast of a rate.

Never operate this machine without good visibility or light.

13.
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

14.
or not in use.

Never operate machine at high transport speeds on

15.
slippery surfaces. Look down and behind and use care
when backing up.

If the machine should start to vibrate abnormally, stop

16.
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

17.
leave the operating position (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

18.
openings. Always use the clean-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

19.
manufacturer (e.g. wheel weights, tire chains, cabs etc.).

When starting engine, pull cord slowly until resistance

20.
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

21.
care and good judgment. Contact Customer Support for
assistance and the name of your nearest servicing dealer.

Tire Pressure (Pneumatic Tires)

The tires are over-inflated for shipping purposes. Check the
tire pressure before operating the snow thrower. Refer to
the tire side wall for tire manufacturer’s recommended psi
and deflate (or inflate) the tires as necessary.

NOTE: If the tire pressure is not equal in both tires, the unit
may pull to one side or the other and the shave plate will
not sit level on the ground.

IMPORTANT: Under any circumstance do not exceed
manufacturer’s recommended psi. Equal tire pressure
should be maintained at all times. Excessive pressure when
seating beads may cause tire/rim assembly to burst with
force sufficient to cause serious injury. Refer to sidewall of
tire for recommended pressure.

Adjustments

Skid Shoes

The snow thrower skid shoes are adjusted upward at the
factory for shipping purposes. Adjust them downward, if
desired, prior to operating the snow thrower.

CAUTION: It is not recommended that you
operate this snow thrower on gravel as it can
easily pick up and throw loose gravel, causing
personal injury or damage to the snow thrower
and surrounding property.

For close snow removal on a smooth surface, adjust the

•
skid shoes so that the shave plate on the bottom of the
auger housing is just off the ground.

Adjust the skid shoes to a lower position to raise the

•
shave plate off the ground when clearing uneven areas,
such as a ribbon type driveway or a gravel driveway

NOTE: If you choose to operate the snow thrower on a gravel
surface, keep the skid shoes in position for maximum clearance
between the ground and the shave plate.

To adjust the skid shoes:

Adjust skid shoes by loosening the six (three on each

1.
side) hex nuts, washers, and carriage bolts securing the
skid shoes to the auger housing. Refer to Figure 3-10.

While observing the distance between the shave plate

2.
and the ground, adjust the skids shoes up or down to
achieve the desired shave plate height. See Figure 3-10.

Make certain the entire bottom surface of skid shoes are

3.
against the ground to avoid uneven wear on the skid
shoes; then tighten nuts and bolts securely.

Auger and Drive Control Cables

WARNING! Prior to operating your snow

thrower, carefully read and follow all instructions
below. Perform all adjustments to verify your
snow thrower is operating safely and properly.

Testing Auger Drive Control

When the auger control is released and in the disen-

1.
