Preparing The Engine; Off-Season Storage - Sears Craftsman 450 Serie Manual De Uso

Preparing the Engine

Engines stored between 30 and 90 days need to be treated with a gasoline stabilizer
and engines stored over 90 days need to be drained of fuel to prevent deterioration
and gum from forming in fuel system or on essential carburetor parts. If the
gasoline in your engine deteriorates during storage, you may need to have the
carburetor, and other fuel system components, serviced or replaced.
1. Remove all fuel from tank by running engine until it stops from lack of fuel.
Never leave engine unattended while it is running.
2. Change the oil. See Change Engine Oil in Service and Maintenance section.
3. Remove spark plug and pour about a 1⁄2 ounce of engine oil into the cylinder.
Replace spark plug and crank it slowly to distribute oil.
4. Clean debris from around the engine and the muffler. Touch up any damaged
paint, and coat other areas that may rust with a light film of oil.
5. Store in a clean, dry and well ventilated area away from any appliance that
operates with a flame or pilot light, such as a furnace, water heater, or clothes
dryer. Also avoid any area with a spark producing electric motor, or where
power tools are operated.
6. If possible, also avoid storage areas with high humidity, because that promotes
rust and corrosion.
7. Keep the engine level in storage. Tilting can cause fuel or oil leakage.

OFF-SEASON STORAGE

Never store tiller with fuel in tank indoors or in poorly ventilated areas
where fuel fumes may reach an open flame, spark, or pilot light as on a
furnace, water heater, clothes dryer, or gas appliance.
