Engine
Refer to the separate engine manual packed with your unit for all engine maintenance procedures.
Off-Season Storage
WARNING: Never store the machine or fuel container indoors where there is an open flame, spark, or pilot light such as on water heater, furnace, 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.
NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Do not drain carburetor if using fuel stabilizer.
•Wipe equipment with an oiled rag to prevent rust.
•Remove spark plug and pour one ounce of engine oil through spark plug hole into cylinder. Cover spark plug hole with rag. Crank engine several times to distribute oil. Replace spark plug.
•Follow the lubrication recommendations found in the Maintenance Section.
•Always store the snow thrower in a clean, dry area.
NOTE: When storing any type of power equipment in an unventilated or metal storage shed, care should be taken to rust proof the equipment. Using a light oil or silicone, coat the equipment, especially any chains, springs, bearings, and cables.
