Chute Assembly
The distance that snow is thrown can be adjusted by
adjusting the angle of the chute assembly. Refer to
the Controls section of this manual.
• The remote chute control cables have been pre-
adjusted at the factory. Move the remote chute
lever on the control panel back and forward to
adjust angle of the chute asssembly.
Skid Shoe
The space between the shave plate and the ground
can be adjusted. For close snow removal, place skid
shoes in the low position. Use middle or high position
when area to be cleared is uneven.
• Adjust skid shoes by loosening the four hex nuts
and carriage bolts and moving skid shoes to
desired position.
• Make certain the entire bottom surface of skid
shoe is against the ground to avoid uneven wear
on the skid shoes.
• Retighten nuts and bolts securely.
NOTE: It is not recommended that you operate this
snow thrower on gravel as loose gravel can be easily
picked up and thrown by the auger causing an injury
or damage to the snow thrower.
• If for some reason, you have to operate the
snow thrower on gravel, keep the skid shoe in
the highest position for maximum clearance
between the ground and the shave plate.
Traction Drive Clutch
Refer to the Final Adjustment section of the Set-Up
Instructions to adjust the traction drive clutch. To
check the adjustment, proceed 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 six
self-tapping screws.
• With the traction drive clutch released, there
must be clearance between the friction wheel
SERVICE & ADJUSTMENTS
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
(shown in Figure 30).
• If adjustment is necessary, loosen the jam nut
on the traction drive cable and thread the cable
in or out as necessary. See Figure 22. Tighten
the jam 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.
