FINAL ADJUSTMENTS

Auger and Traction Control Clutch Adjustment

To check the adjustment of either drive clutch, push forward on the clutch grip (depress the rubber bumper). There should be slack in the cable. Release the clutch grip. The cable should be straight, but not tight. Make certain you can depress the clutch grip against the handle completely.

If necessary, thread lock-nut up to increase tension or down to decrease tension. See Figure 7.

Skid Shoe Adjustment (See Figure 8)

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 8.

Adjust skid shoes by loosening the six 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. Tighten nuts and bolts securely. The skid shoes may be reversed for even wear.

Shift Lever Adjustment (See Figure 9)

If unit does not engage properly into first gear, it may be necessary to remove the cotter pin and washer from the shift rod and thread the ferrule one counterclockwise turn.
