NOTE: It may be helpful to read Section 3, Knowing Your Snow Thrower, to help identify certain areas of the snow thrower before performing adjustments.

Traction Control and Shift Lever

To check the adjustment of the traction control and shift lever, proceed as follows:

Move the shift lever into sixth (6) position.

With the traction control released, push the snow thrower forward, then pull it back. The machine should move freely.

Engage the traction control and attempt to move the machine both forward and back, resistance should be felt.

Move the shift lever into the fast reverse (R2) position and repeat the previous two steps.

If you experienced resistance rolling the unit, either when repositioning the shift lever from 6 to R2 or when attempting to move the machine with the traction control released, adjust the traction control immediately. To adjust, proceed as follows:

Loosen the jam nut on the traction control cable and UNTHREAD the cable one full turn.

Recheck adjustment.

Retighten the jam nut to secure the cable when correct adjustment is reached.

NOTE: For more details, refer to Traction Control Adjustment
