STORAGE
If you are going to store your generator for more than 30
days, use the following information as a guide to
prepare the generator for storage.
Never store generator with fuel in the tank indoors
or in enclosed, poorly ventilated areas, where
fumes can reach an open flame, spark or pilot light
as on a furnace, water heater, clothes dryer or
other gas appliances.
Engine Preparation
1. Add fuel stabilizer to fuel tank to minimize the
formation of fuel gum deposits during storage.
2. Run engine at least 5 minutes after adding stabi-
lizer to allow it to enter the fuel system.
3. Next shut off engine.
4. Disconnect the spark plug wire and remove the
spark plug.
5. Add one teaspoon of oil through the spark plug
hole.
6. Place rag over spark plug hole and pull the recoil a
few times to lubricate the combustion chamber.
7. Replace the spark plug, but do not connect the
spark plug wire.
NOTE: If a fuel stabilizer is not used, all gasoline
must be drained from the tank and carburetor to
prevent gum deposits from forming on these parts and
causing possible malfunction of the engine.
Generator
• Clean the generator as outlined in the Maintenance
Section on this manual.
• Check that cooling air slots and openings on
generator are open and unobstructed.
