ADJUSTMENTS & MAINTENANCE
1. Remove the carriage bolts and hex lock nuts which attach it to the
snow thrower housing.
2. Install new shave plate (or reverse), making sure the heads of the
carriage bolts are on the inside of the housing.
3. Adjust the shave plate according to instructions above
4. Tighten securely.
Control Cable
As a result of both the control cable and the drive belt stretching due to
wear, periodic adjustments may be necessary.
If the auger seems to hesitate when rotating while the engine
maintains a constant speed, an adjustment is necessary. Proceed as
follows:
The upper hole in the control handle provides for an adjustment in
cable tension. To adjust, disconnect the end of control cable from the
bottom hole in the control handle and reinsert it in the upper hole.
Insert the cable from the outside as shown in Figure 8. Test the snow
thrower to see if there is a noticeable difference.

WARNING: NEVER attempt to make any adjust-
ments while the engine is running, except where
specified in the operator’s manual.
Shave Plate
1. To check the adjustment of the shave plate, place the unit on a level
surface. The wheels, shave plate and augers should all contact
level surface. Note that if the shave plate is adjusted too high, snow
may blow under the housing. If the shave plate wears out exces-
sively, or the unit does not self-propel, the shave plate may be too
low and needs to be adjusted.
NOTE: On new units or units with a new shave plate installed, the
augers may be slightly off the ground.
WARNING: Run the engine completely dry of
gasoline before tipping snowthrower.
2. To adjust, tip the snow thrower back so that it rests on the handle.
3. Loosen the four lock nuts and bolts which secure the shave plate to
the housing. See Figure 7. Move the shave plate to desired position
and retighten the nuts and bolts securely.
4. Tip the snow thrower back to the operating position and pull the
starter handle a few times to see if it is difficult to pull.
5. If the starter is difficult to pull, remove the spark plug and pull the
handle several times to ensure that any oil trapped in the head is
removed.
Caution: Oil may come out of the spark plug hole when it is removed
and the starter handle is pulled.
6. Inspect the spark plug. If it is wet, clean off any oil before re-
installing.
Replacing Shave Plate
The shave plate is attached to the bottom of the auger housing and
is subject to wear. It should be checked periodically. There are two
wearing edges and the shave plate can be reversed. Refer to Figure 7.
To replace or reverse the shave plate proceed as follows:

Replacing Belt
WARNING: Before servicing, repairing, or inspect-
ing, disengage the control bail and stop engine. Wait
until all moving parts have come to a complete stop.
Remove the belt cover by removing five hex screws. See Figure 9.
Then simply pull the belt off by grasping it from the bottom of the auger
pulley and pulling off. Once you remove the belt from the pulleys, you
can push down on the idler pulley to release the belt from under belt
keeper.
