Adjustments
WARNING! 
Before servicing, repairing or 
inspecting the snow thrower, disengage the auger 
control. Stop the engine and remove the key to 
prevent unintended starting.
Shave Plate
To check the adjustment of the shave plate, place the machine 
on a level surface. The wheels, shave plate and auger should all 
contact the level surface. Note that if the shave plate is adjusted 
too high, snow may blow under the housing. If the shave plate 
wears out excessively, or the snow thrower does not self-propel, 
the shave plate may be too low and needs to be adjusted.
NOTE: On new snow throwers or machines with a new shave 
plate installed, the auger may be slightly off the ground.
To adjust the shave plate proceed as follows:
Drain the gas from the snow thrower by running the 
1. 
engine until it is empty.
Pull the recoil starter handle until resistance is felt. Then tip 
2. 
the snow thrower back until it rests on the handles.
Loosen the four flange lock nuts and carriage bolts which 
3. 
secure the shave plate to the housing. See Fig. 6-1. Move 
the shave plate to the desired position and retighten the 
nuts and bolts securely.
Tip the snow thrower back to the operating position and pull 
4. 
the starter handle a few times to see if it is difficult to pull.
If the starter is difficult to pull, remove the spark plug and 
5. 
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.
Inspect the spark plug. If it is wet, clean off any oil before 
6. 
re-installing.
Control Cable
As a result of both the control cable and the auger drive belt 
stretching due to wear, periodic adjustments may be necessary. If 
the auger seems to hesitate when rotating, 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 Fig. 6-2.
Test the snow thrower to see if there is a noticeable difference. If after 
the adjustment to the control cable the auger still hesitates when 
rotating, see the Service section for instructions on replacing the belt.
