Friction Wheel Rubber

Follow the instructions below to check the condition of the friction wheel rubber every 25 hours of operation.

•Remove the six self-tapping screws from the frame cover underneath the snow thrower.

•Visually inspect the friction wheel rubber for excessive wear, cracks, or loose fit on the friction wheel drive hub.

•Also engage the traction control and check if the friction wheel is making contact with friction plate. Refer to Figure 14. If it does not make contact, adjust the traction drive cable and recheck the friction wheel.

•Replace friction wheel rubber if necessary. Refer to instructions on page 17.

Drive Belts

Follow the instructions below to check the condition of the drive belts every 50 hours of operation.

•Remove the plastic belt cover on the front of the engine by removing the three self-tapping screws.
