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.

a. Use only an approved gasoline container.
b. Extinguish all cigarettes, cigars, pipes and other

sources of ignition.
c. Never fuel machine indoors.
d. Never remove gas cap or add fuel while the engine is

hot or running.
e. Allow engine to cool at least two minutes before

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

inch below bottom of filler neck to provide space for

fuel expansion.
g. Replace gasoline cap and tighten securely.
h. If gasoline is spilled, wipe it off the engine and

equipment. Move machine to another area. Wait 5

minutes before starting the engine.
i. Never store the machine or fuel container inside

where there is an open flame, spark or pilot light

(e.g. furnace, water heater, space heater, clothes

dryer etc.).
j. Allow machine to cool at least 5 minutes before

storing.
k. 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.
l. 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.
m. 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

1. 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.

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

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

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

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

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

7. Muffler and engine become hot and can cause a burn. Do
not touch. Keep children away.

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

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

10. 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.

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

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

13. 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.

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

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

16. 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.

17. Disengage all control levers and stop engine before you
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.

18. Never put your hand in the discharge or collector 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.

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

20. When starting 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.

21. If situations occur which are not covered in this manual, use
care and good judgment. Contact Customer Support for
assistance and the name of your nearest servicing dealer.

Refer to “Assembly and Set-Up” section.

Shave Plate and Skid Shoes

The shave plate and skid shoes on the bottom of the snow
thrower are subject to wear. They should be checked periodically
and replaced when necessary.

NOTE: Some units are equipped with reversible skid shoes and
may be turned over to increase their lifespan.

To remove skid shoes:

1. Remove the four carriage bolts and hex flange nuts which
secure them to the snow thrower.

2. Reassemble new skid shoes with the four carriage bolts
(two on each side) and hex flange nuts. Refer to Fig. 6-1.

To remove shave plate:

3. Remove the carriage bolts and hex nuts which attach it to
the auger housing.

4. Reassemble new shave plate, making sure heads of carriage
bolts are to the inside of housing. Tighten securely.

Lubrication

Gear Shaft

The gear (hex) shaft should be lubricated at least once a season
or after every twenty-five (25) hours of operation.

1. Allow the engine to run until it is out of fuel.

2. Carefully pivot the snow thrower up and forward so that it
rests on the auger housing.

3. Remove the frame cover from the underside of the snow
thrower by removing the self-tapping screws which secure
it. Refer to Fig 7-4.

4. Apply a light coating of Regular Grade Anti-Seize to the hex
shaft. See Figure 6-2.

NOTE: When lubricating the hex shaft, be careful not to get
any anti-seize on the aluminum drive plate or the rubber
friction wheel. Doing so will hinder the snow thrower’s
drive system. Wipe off any excess.

Chute Assembly

Refer to the Assembly & Set-up section for instructions on
adjusting the chute assembly.

Skid Shoes

Refer to the Assembly & Set-up section for instructions on
adjusting the skid shoes.

Drive Control

When the drive control is released and in the disengaged “up”
position, the cable should have very little slack. It should NOT be
tight.

NOTE: If excessive slack is present in the drive cable or if the snow
thrower’s drive is disengaging intermittently during operation,
the cable may be in need of adjustment.

Check the adjustment of the drive control as follows:

1. With the drive control released, push the snow thrower
gently forward. The unit should roll freely.

2. Engage the drive control and gently attempt to push the
snow thrower forward. The wheels should not turn. The
unit should not roll freely.

3. With the drive control released, move the shift lever back
and forth between the R2 position and the F6 position
several times. There should be no resistance in the shift
lever.

If any of the above tests failed, the drive cable is in need of
adjustment. Proceed as follows:

1. Loosen the lower hex screw on the drive cable bracket. See
Fig. 6-5.

2. Position the bracket upward to provide more slack (or
downward to increase cable tension).

3. Retighten the upper hex screw.
