SECTION 8: ADJUSTMENTS
WARNING:
NEVER attempt to clean
chute or make any adjustments while
engine is running.
CHUTE ASSEMBLY ADJUSTMENT
The distance snow is thrown can be adjusted by
adjusting the angle of the chute assembly. Refer to
the Control section of this manual.
SKID SHOE ADJUSTMENT
The space between the shave plate and the ground
can be adjusted. Refer to the Final Adjustments
section page 9.
TRACTION DRIVE CLUTCH ADJUSTMENT
Refer to the Final Adjustment section of the
Assembly Instructions to adjust the traction drive
clutch. If you are uncertain that you have reached
the correct adjustment, the adjustment can be
physically checked as follows.
With the snow thrower tipped forward (be certain to
drain the gasoline or place plastic film under the gas
cap if the snow thrower has already been operated),
remove the frame cover underneath the snow
thrower by removing four self-tapping screws.
With the traction drive clutch released, there must
be clearance between the friction wheel and the
drive plate in all positions of the shift lever. With the
traction drive clutch engaged, the friction wheel
must contact the drive plate. See figure 17.
If adjustment is necessary, loosen the lock nut on
the traction drive cable and thread the cable in or
out as necessary. Tighten the lock nut to secure the
cable when correct adjustment is reached.
Reassemble the frame cover.
NOTE: If you placed plastic under the gas cap, be
certain to remove it.

CARBURETOR ADJUSTMENT
WARNING:
If any adjustments are

surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
