Changing Friction Wheel Rubber
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 as follows:
•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. See Figure 11.
•Remove the six
•Remove the klick pins which secure the wheels, and remove the wheels from the axle.
•Using a wrench to hold the shaft, loosen, but do not completely remove, the hex nut and bell washer on left end of gear shaft. See Figure 24.

SECTION 8: OFF-SEASON STORAGE
WARNING: Never store engine with fuel in tank indoors or in enclosed, poorly ventilated areas where fuel fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer, or other gas appliance.
WARNING: Drain fuel into an approved container outdoors, away from an open flame. Allow engine to cool. Extinguish cigarettes, cigars, pipes, and other sources of ignition prior to draining fuel. Fuel left in engine for extended periods deteriorates and will cause starting problems.
If unit is to be stored over 30 days, prepare for storage as follows:
•Remove gasoline from carburetor and fuel tank to prevent gum deposits from forming on these parts and causing possible malfunction of engine.
•Run engine until fuel tank is empty and engine stops due to lack of fuel.
•Drain carburetor by pressing upward on bowl drain, located below the carburetor cover.
