WARNING
Unexpected auger movement may cause personal
injury. Before servicing, repairing or inspecting the
snow thrower, disengage the Auger Control. Stop
the engine and remove the Ignition Key/Safety to
prevent unintended start up.
Adjustments
Shave Plate
To check the adjustment of the shave plate, place the machine on
a level surface. The wheels, shave plate and augers should all
contact the level surface. 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 augers may be slightly off the ground.
To adjust the shave plate:
1. Drain the gas from the snow thrower.
2. Pull the Recoil Starter Handle until resistance is felt.
3. Tip the snow thrower back so that it rests on the handle.
4. Loosen the four lock nuts and bolts that secure the shave
plate to the housing. Move the shave plate to the desired
position and retighten the nuts and bolts securely (see Fig. 16).
5. Tip the snow thrower into the operating position and pull the
Recoil Starter Handle to test if it is difficult to pull. If it is
difficult to pull then remove the spark plug, pull the handle
several times to ensure trapped oil in the Head is removed.
6. Inspect the spark plug. If it is wet, clean off any oil and
re-install.
Control Cable
Wear causes stretching on both the Control Cable and Auger Drive
Belt, 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 (see Fig.17).
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 “Replacing the Belt” for instructions on
replacing the belt.
