SKID SHOE ADJUSTMENT

The space between the shave plate and the ground can be adjusted. Refer to page 10 of the Assembly Instructions.

TRACTION DRIVE CLUTCH

ADJUSTMENT

Refer to the Final Adjustment section of the Assem- bly 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 oil and gasoline or drain the oil and 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 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 21.

If adjustment is necessary, loosen the hex jam nut on the traction drive cable and thread the cable in or out as necessary. Tighten the hex jam nut to secure the cable when correct adjustment is reached. Reassem- ble the frame cover.

NOTE: If you placed plastic under the gas cap, be certain to remove it.

DRIVE WHEELS

The wheels may be adjusted for two different meth- ods of operation. The adjustment is made by placing the klick pins in one of two different holes on the right side of the unit. See Figure 22.

1.One Wheel Driving—Place klick pin in the out- side axle hole on the right side. This position gives power drive to the left wheel only, making the unit easier to maneuver.

2.Both Wheels Driving—Both Wheels Driving— Rotate wheel assembly to align hole in hub with inner hole on axle shaft. Insert klick pin in hole. Outer axle shaft hole should be visible. This position is good for heavy snow as there is power to both wheels. See Figure 22.
