(Figure 25) Note the position of the friction
wheel (4). The correct distance "A" from the
right side of the friction wheel (4) to the
outside of the motorbox is as follows:
Tire Size Distance "A"
12 and 13 inch 4-1/8" (10.5 cm)
16 inch 4-5/16" (10.95 cm)
If the friction wheel (4) is not in the correct
position, adjust as follows.
How To Adjust The Friction Wheel
1. (Figure 1) Position the shift speed lever (6)
in the lowest forward speed.
2. (Figure 9) Loosen the bolts (1) on the
speed control rod (8).
3. (Figure 25) Move the friction wheel (4) to
the correct position.
4. (Figure 9) Tighten the bolts (1) on the
speed control rod (8).
5. (Figure 23) Install the bottom panel (2).
6. Tighten the bolts (3) on each side of the
bottom panel (2).
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.
1. (Figure 1) Remove the gas from the gas
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.
2. Disconnect the spark plug wire.
3. (Figure 29) Remove the fasteners that
secure the left wheel (10). Remove the left
wheel (10) from the axle (11).
4. Loosen the bolts (3) on each side of the
bottom panel (2).
5. Remove the bottom panel (2).
6. (Figure 30) Remove the fasteners that
secure the drive sprocket (12) to the axle
(11).
7. Remove the right wheel, axle (11), and drive
sprocket (12).
8. (Figure 31) Remove the four bolts (16) that
hold the bearings (7) on each side of the
hex shaft (8).
9. (Figure 32) Remove the hex shaft (8) and
bearings (7).
NOTE: Take special note of the position of
the washers (17).
10. (Figure 27) Remove the three fasteners (4)
that hold the friction wheel (5) to the hub
(6).
11. (Figure 27) Remove the friction wheel (5)
from the hub (6). Slip the friction wheel (5)
off the hex shaft (8).
12.Assemble the new friction wheel (5) onto
hub (6) with the fasteners removed earlier.
13.(Figure 32) Install the hex shaft (8) and
bearings (7) with the four bolts removed
earlier.
Make sure the washers (17) are properly
installed in the original position. Also,
make sure the two washers (13) are
properly aligned with the actuator arms
(14).
14. Make sure the hex shaft (8) turns freely.
15.(Figure 30) install the right wheel, axle (11),
and drive sprocket (12) with the fasteners
removed earlier. Install the chain (15) onto
the drive sprocket (12).
16. Check the adjustment of the friction wheel.
See "How To Adjust The Friction Wheel" in
this section.
17. Make sure the fdction wheel and the disc
drive plate are free from grease or oil.
18.(Figure 23) Install the bottom panel (2).
19.Tighten the bolts (3)on each side of the
bottom panel (2).
20. Install the left wheel (10) to the axle (11)
with the fasteners removed earlier.
21. Connect the spark plug wire.
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.
1. (Figure 1) Move the stop switch (13) to the
stop position. Disengage all controls.
2. Disconnect the spark plug wire. Make sure
all moving parts have stopped.
3. (Figure 14) Lubricate the auger shaft Zerk
fitting (1), if equipped, with a grease gun.
4. (Figure 26) Align the hole in the auger with
the hole in the auger shaft. Install the new
shear bolt (2), spacer (3), and Iocknut (4).
5. Connect the spark plug wire.
How To Prepare The Snow Thrower For
Storage
_ ARNING: 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. Thoroughly clean the snow thrower.
6. Lubricate all lubrication points. See the
Maintenance section.
7. Be sure that all nuts, bolts and screws are
securely fastened. Inspect all visible moving
parts for damage, breakage and wear.
Replace if necessary.
8. Cover the bare metal parts of the blower
housing, auger, and the impeller with spray
rust preventative lubricant.
9. 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.
10. If the machine must be stored outdoors,
block up the snow thrower to be sure the
entire machine is off the ground.
11 .Cover the snow thrower with a suitable
protective cover that does not retain
moisture. Do not use plastic.
