Replacing Auger Paddles
The snow thrower auger’s rubber paddles are subject to wear
and should be replaced if any signs of excessive wear are present.
CAUTION:
Do NOT allow the auger’s rubber
paddles to wear to the point where portions of the
metal auger itself can come in contact with the
pavement. Doing so can result in serious damage to
your snow thrower.
To change the rubber paddles, proceed as follows:
1.
Run the snow thrower until the fuel tank is empty.
2. Pull the recoil starter handle until resistance is felt. Then tip
the snow thrower back until it rests on the handles.
3. Remove the existing rubber paddles by unthreading the hex
washer screws which secure them to the auger. See Fig. 7-4.
NOTE: The auger paddles should be replaced one-at-a-time
so that the auger still attached can be used as an example for
positioning and re-installing the new auger.
4. Secure the replacement rubber paddles to the auger using
the hardware removed earlier.

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.
1.
Run the snow thrower until the fuel tank is empty.
2. Pull the recoil starter handle until resistance is felt. Then tip
the snow thrower back until it rests on the handles.
3. Remove the four carriage bolts and flange lock nuts which
attach it to the snow thrower housing. See Fig. 7-5.
4. Install the new shave plate, making sure the heads of the
carriage bolts are on the inside of the housing.
5. 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.
6. 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.
7. Inspect the spark plug. If it is wet, clean off any oil before
re-installing.
8. Adjust the shave plate as instructed in the Maintenance &
Adjustments section.
9. Tighten securely once adjusted.
