Servicing Friction Wheel Rubber
WARNING: Disconnect the spark plug wire
and ground it against the engine to prevent
unintended starting. Drain fuel into an
approved container or place a piece of plastic
film underneath the gas cap to prevent
gasoline from leaking. 
The rubber on the friction wheel is subject to wear and 
should be checked after 25 hours of operation, and 
periodically thereafter. Replace the friction wheel 
rubber if any signs of wear or cracking are found.
