How To Replace The Friction Wheel

If the friction wheel is worn or damaged, the
snow thrower will not move forward. The friction
wheel must be replaced as follows.

tank. Stand the snow thrower up on the front
end of the

auger housing (4)

WARNING: Drain the gasoline
outdoors, away from fire or flame.

How To Replace the Auger Shear Bolt

The augers are secured to the auger shaft with
special shear bolts. These shear bolts are
designed to break and protect the machine if an
object becomes lodged in the auger housing. Do
not use a harder bolt as the protection provided
by the shear bolt will be lost.

WARNING: For safety and to
protect the machine, use only
original equipment shear bolts.

To replace a broken shear bolt, proceed as
follows. Extra shear bolts were provided in the
assembly parts bag.

(Figure 1)

Move the

stop switch (13)

to the

stop position. Disengage all controls.

2. Pull out the

safety key (8).

Make sure

all moving parts have stopped.

(Figure 14)

Lubricate the auger shaft

Zerk

fitting (1),

if equipped, with a grease gun.

(Figure 26)

Align the hole in the auger with

the hole in the auger shaft. Install the new

shear bolt (2), spacer (3),

and

locknut (4).

How To Prepare The Snow Thrower For
Storage

WARNING: Do not remove gasoline
while inside a building, near a fire,
or while you smoke. Gasoline

fumes can cause an explosion or a fire.

If the snow thrower is to be stored for an
extended period, refer to the engine
manufacturer’s operating manual (included with
some models) for important maintenance or
storage details.

1. Drain the fuel tank.
2. Let the engine run until it is out of gasoline.

3. Never store the snow thrower with fuel in the

tank inside a building where ignition sources
are present such as hot water and space
heaters, clothes dryers, and the like. Allow the
engine (motor) to cool before storing in any
enclosure.

4. Drain the oil from the warm engine. Fill the

engine crankcase with new oil.

5. Remove the spark plug and pour about 15 ml

(1/2 oz) of engine oil into the cylinder.
Replace the spark plug and crank slowly to
distribute the oil.

6. Thoroughly clean the snow thrower.
7. Lubricate all lubrication points. See the

Maintenance section.

8. Be sure that all nuts, bolts and screws are

securely fastened. Inspect all visible moving
parts for damage, breakage and wear.
Replace if necessary.

9. Cover the bare metal parts of the blower

housing, auger, and the impeller with spray
rust preventative lubricant.

10. Put the unit in a building that has good

ventilation. Store in a clean and dry area, but
NOT near a stove, furnace or water heater
which uses a pilot light or any device that can
create a spark.

11. If the machine must be stored outdoors,

block up the snow thrower to be sure the
entire machine is off the ground.

12. Cover the snow thrower with a suitable

protective cover that does not retain
moisture. Do not use plastic.
