Traction Drive Clutch and Shift Lever
Adjustment
To check the adjustment of the traction drive clutch
and shift lever, move the shift lever all the way
forward to sixth (6) position. With the traction drive
lever released, push the snow thrower forward. The
unit should move forward freely. Then engage the
traction drive clutch grip. The wheels should stop
turning.
Now release the traction drive clutch grip, and push
the unit again. Move the shift lever back to the fast
reverse position, then all the way forward again.
There should be no resistance in the shift lever, and
the and the wheels should keep turning.
If you have resistance when moving the shift lever
or the wheels stop when they should not, loosen the
jam nut on the traction drive cable and unthread the
cable one turn. If the wheels do not stop when you
engage the traction drive clutch grip, loosen the jam
nut on the traction drive cable and thread the cable
in one turn. Recheck the adjustment and repeat as
necessary. Tighten the jam nut to secure the cable
when correct adjustment is reached.
NOTE: If you are uncertain that you have reached
the correct adjustment, refer to the Adjustment sec-
tion on page 14.
ADJUSTING THE SKID SHOES
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. See Figure 13.
Adjust skid shoes by loosening the four hex nuts and
carriage bolts and moving skid shoes to desired posi-
tion. 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.
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.

TIRE PRESSURE (Pneumatic Tires)
The tires are over-inflated for shipping purposes.
Check tire pressure and reduce to 15 to 20 psi.
NOTE: If the tire pressure is not equal in both
tires, the unit may pull to one side or the other .
SECTION 6: CONTROLS

The shift lever is located in the center of the handle
panel. The shift lever may be moved into one of eight
positions. Run engine with throttle in the fast position.
Use the shift lever to determine ground speed.
Forward— one of six speeds.
Position number one (1) is the
slowest. Position number six (6) is
the fastest.
