Adjustments
Engine
Refer to 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 engine and remove the key to prevent
unintended starting.
Shave Plate
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 excessively, 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.
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 Figure 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 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 as shown in Figure 6-2. Test the snow thrower to see
if there is a noticeable difference.
Chute Assembly
Refer to the Assembly and Set-up section for instructions on
adjusting the chute assembly.
Maintenance
Lubrication
Lubricate pivot points on the control handle and the extension
spring at the end of the control cable with 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
storage instructions below.
Store equipment in a clean, dry area.
If storing the snow thrower in an unventilated area,
rustproof the machine using a light oil or silicone to coat
the snow thrower.
