The rubber on the friction wheel is subject to wear and should be checked after the first 25 hours of operation, and periodically thereafter. Replace the friction wheel if any signs of wear or cracking are found.
•Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.
•Tip the snow thrower up and forward, so that it rests on the housing.
•Remove screws from the frame cover underneath the snow thrower. See Figure
•Remove the right wheel from the axle.

the hex screw and cupped washer and bearing from left side of the frame. Refer to Figure
