SERVICE & ADJUSTMENTS
A
WARNING: Always stop the engine,
disconnect spark plug wire and move it away
from the spark plug before performing any
adjustments or repairs.
Adjustments
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.
WARNING: Never attempt to clean chute or
make any adjustments while engine is running.
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 Ciutch
Refer to the Final Adjustment section of the Assembly
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 sixself-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 (Figure 34).
• If adjustment is necessary, loosen the jam nut on
the traction drive cable and thread the cable in or
out as necessary. See Figure 26. 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
