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 1.
machine on a level surface. The wheels, shave plate and
augers 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 augers may be slightly off the
ground.
To adjust the shave plate, tip the snow thrower back so that
2.
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 the 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. If
after the adjustment to the control cable the auger still hesitates
when rotating, see the Service Section for instructions on
replacing the belt.
Chute Assembly
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 the snow thrower is put into
storage 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.
Store the equipment in a clean, dry area. 1.
If storing the snow thrower in an unventilated area, rustproof 2.
the machine using a light oil or silicone to coat the snow
thrower.
Clean the exterior of the engine and the snow thrower.
