SECTION 5: MAKING ADJUSTMENTS
Shave Plate
•
To check the adjustment of the shave plate, place
the unit on a level surface. See Figure 8. 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.
Figure 8
•
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 9. Move the shave plate to desired position
and retighten the nuts and bolts securely.
Figure 9
Belt Tension
Periodic adjustment of the belt tension may be required
due to normal stretch and wear on the belt. Adjust the
belt tension, following instructions below, if the augers
seem to hesitate while turning although engine
maintains the same speed.
•
The upper hole in the control handle provides
adjustment for belt tension. To adjust, disconnect
the “Z” end of control cable from the bottom hole in
the control handle. See Figure 10 . Hook the cable
into the upper hole in control handle as shown.
Figure 10
If additional adjustment is required, follow steps below.
•
Remove the belt cover by removing five hex screws
that hold it in place. See Figure 12.
•
There are three adjustment holes provided in the
idler bracket assembly. See Figure 11. To adjust,
move the extension spring on the end of the clutch
cable to the next higher adjustment position on the
idler bracket assembly. Reassemble belt cover.

Carburetor
•
Refer to the separate engine manual, packed with
your unit, for carburetor adjustment information.

NEVER attempt to make any
adjustments while the engine is running,
except where specified in the snow thrower
and/or engine operator’s manuals.
