Changing Friction Wheel Rubber
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
rubber 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 the six self-tapping screws from the frame
cover underneath the snow thrower.
