Maintenance, Traction Control Adjustment

Minor carburetor adjustment may be required to com- pensate for differences in fuel, temperature, altitude and load.

Refer to the separate engine manual packed with your unit for carburetor adjustment information.

TRACTION CONTROL ADJUSTMENT

Refer to the FINAL ADJUSTMENTS in SECTION 4: ASSEMBLY to adjust the traction control. If you are uncertain that you have reached the correct adjust- ment, 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 control released, there must be clearance between the friction wheel and the drive plate in all positions of the shift lever. With the trac- tion control engaged, the friction wheel must contact the drive plate. See Figure 16.

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

SKID SHOE ADJUSTMENT

The space between the shave plate and the ground can be adjusted by adjusting the skid shoe. Slide the skid shoe upwards and lower the housing to remove snow close to the ground. Slide skid shoe down- wards and raise the housing to remove snow from uneven ground like gravel. For more details, refer to FINAL ADJUSTMENTS in SECTION 4: ASSEM- BLY.

DRIVE WHEEL

The wheel may be adjusted for two different methods of operation. The adjustment is made by placing the klick pin in one of two different holes on the right side of the unit. See Figure 17.

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 - 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.
