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. Do not operate on steep 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.

3. Release the auger control; the interlock mechanism should
keep the auger control engaged until the drive control is
released.

4. Release the drive control to stop both the augers and
the wheel drive. To stop the auger, both levers must be
released.

Replacing Shear Pins

Each of the auger spiral assemblies are secured to the spiral
shaft with a shear pin and cotter pin. If the auger should strike a
foreign object or ice jam, the snow thrower is designed so that
the pins may shear. If the augers will not turn, check to see if the
pins have sheared. See Figure 5-1.

CAUTION: NEVER replace the auger shear pins

with anything other than OEM Part No. 738-04155
replacement shear pins. Any damage to the auger
gearbox or other components as a result of failing to
do so will NOT be covered by your snow thrower’s
warranty.

WARNING! Always turn off the snow thrower’s

engine and remove the key prior to replacing shear
pins.

Operating Tips

NOTE: Allow the engine to warm up for a few minutes. The
engine will not develop full power until it reaches operating
temperature.

WARNING: The temperature of the muffler and

the surrounding areas may exceed 150° F. Avoid
these areas.

1. If possible, remove snow immediately after it falls.

2. Discharge snow downwind whenever possible.

3. Slightly overlap each previous path.

4. Set the skid shoes 1/4” below the shave plate for normal
usage. Adjust them upward for hard-packed snow and
downward when using on gravel or crushed rock.

Maintenance

WARNING! Before servicing, repairing, lubricating,

or inspecting, disengage all controls and stop
engine. Wait until all moving parts have come to a
complete stop. Remove the ignition key, disconnect
the spark plug wire and ground it against the engine
to prevent unintended starting. Always wear safety
glasses during operation or while performing any
adjustments or repairs.

Engine

Refer to the Engine Operators Manual Maintenance included
with the snow thrower.

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: The skid shoes on this machine have two wear edges. When
one side wears out, they can be rotated 180° to use the other edge.

To Replace skid shoes:

1. Remove the six carriage bolts and flange lock nuts that
secure the two skid shoes to the sides of the auger housing.
Refer to Figure 6-1.

3. Slide the shave plate out of the off-set slot at the bottom
of the housing, and from between the skid shoes and side
panels of the housing.

4. With the mounting holes facing toward the back of the
unit, slide the new shave plate into position and secure
with the fasteners previously removed and loosened.

Lubrication

Gear Shaft

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

NOTE: Before tipping the unit on the front housing, run the fuel
tank empty so fuel does not leak out of the fuel cap.

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

2. Remove the frame cover from the underside of the snow
thrower by removing the self-tapping screws which secure
it. Refer to Figure 6-6.

3. Apply a light coating of engine oil (or 3-in-1 oil) to the hex
shaft. See Figure 6-2.

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

4. At least once a season grease the wheel axle with Arctic
grease, part number 737-0318. The grease fitting is located
on the wheel axle tube behind the wheel axle support
bracket.

2. Position the new skid shoes and secure with the carriage

Auger Shaft

At least once a season, one at a time, remove the shear pins from
the auger shaft. Spray lubricant inside the hub of each auger
spiral assembly and around the spacers on the auger shaft. See
Figure 6-3.

Grease fittings can also be found at each end of the auger shaft.
Lubricate with a grease gun once a season. SeeFigure 6-3.

1. Place the shift lever in the fastest forward speed position.

2. Loosen the hex nut on the shift cable index bracket. See
Figure 6-1.

3. Pivot the bracket downward to take up slack in the cable.

4. Retighten the hex nut.

Gear Case

The auger gear case is equipped with a grease fitting. Lubricate
with grease once a season (order part number 737-0168). See
Figure 6-3.

NOTE: To relieve pressure, remove the vent plug before
lubricating the gear case. See Figure 6-3. Failure to do so could
result in damage to the gear case seals.

Augers

Each of the auger spiral assemblies is secured to the spiral shaft
with a shear pin and cotter pin. If the auger should strike a
foreign object or ice jam, the snow thrower is designed so that
the pins may shear.

1. If augers do not turn, check to see if pins have sheared.

2. Replace the pins if needed. Two replacement shear pins
and cotter pins have been provided with the snow thrower.
Spray an oil lubricant into shaft before inserting new pins
and securing with new cotter pins.

Adjustments

Chute Bracket Adjustment

If the spiral at the bottom of the chute directional control is not
fully engaging with the chute assembly, the chute bracket can be
adjusted. To do so:

1. Loosen the two nuts which secure the chute bracket and
reposition it slightly. See Figure 6-5.

2. Retighten the nuts.

Shift Cable

If the full range of speeds (forward and reverse) cannot be
achieved, refer to the Figure 6-4 and adjust the shift cable as
follows:
