SECTION5: MAKINGADJUSTMENTS
WARNING: NEVER attempt to make any
adjustments while the engine is running, except
where specified in the operator’s manual.
Belt Tension
Periodic adjustment of the belt tension may be required
due to normal stretch and wear on the belt. If augers
hesitate while turning although engine maintains same
speed, adjust tension following instructions below.
Shave Plate
•
To check the adjustment of the shave plate, place
the unit on a level surface. See Figure 12. 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 will not self-propel, the shave plate may
be adjusted too low.
•
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 14 . Hook the cable
into the upper hole in control handle as shown here.

move the extension spring on the end of the clutch
cable to the next higher adjustment position on the

secure the shave plate to the housing. See Figure

and bolts are tightened securely.
