Adjustments
Engine
Refer to the Tecumseh Engine Manual packed with your machine
for all engine maintenance.
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
1. To check the adjustment of the shave plate, place the
machine 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 excessively, or the
unit does not self-propel, the shave plate may be too low
and needs to be adjusted.
NOTE: On new machines or machines with a new shave
plate installed, the augers may be slightly off the ground.
2. To adjust, tip the snow thrower back so that it rests on the
handle. Loosen the four lock nuts and bolts which secure
the shave plate to the housing. See Fig. 6-1. Move the shave
plate to desired position and retighten the nuts and bolts
securely.

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.

Refer to the Assembly and Set-up section for instructions on
adjusting the chute assembly.
Maintenance
Lubrication
Lubricate the pivot points on the control handle and the
extension spring at the end of the control cable with a light oil
once every season and before storage of the snow thrower at the
end of the season.
Off-Season Storage
If the snow thrower will not be used for 30 days or longer, follow
the instructions below.
1. Store the equipment in a clean, dry area.
2. If storing the snow thrower in an unventilated area,
rustproof the machine using a light oil or silicone to coat
the snow thrower.
3. Clean the exterior of the engine and the snow thrower.
