It is important to prevent gum deposits from forming in essential fuel system components such
as the carburetor, fuel hoses or tank during storage. Ethanol-blended fuels (called gasohol, ethanol
or methanol) attract moisture, which leads to separation and formation of acids during storage.
Acidic gas can damage the fuel system of an engine while in storage.
Long Term Storage
When the generator set is being stored for more than one month, follow these instructions to avoid
engine problems:
Do not store fuel near any ignition sources.
When draining fuel move generator outdoors and use a commercially available non-conductive
vacuum siphon. Fuel must be drained into an approved container.
WARNING! Fuel and its vapors are extremely flammable which could cause burns
or fire resulting in death or serious injury.
1-Treat any stored fuel with fuel stabilizer.
2-When storing generator with gasoline in fuel tank, operate the engine for 5-10 minutes to
circulate treated fuel into fuel lines and carburetor before shutdown.
3- There is no need to drain gasoline from the generator fuel tank if fuel stabilizer is added.
4-FUEL STARVATION: If you elect to drain fuel tank move generator outdoors. Once fuel tank is
drained turn fuel valve to on position. Start and run the portable generator outdoors until engine
stops from lack of gasoline. This will drain remaining gasoline from tank, fuel lines, and carburetor.
5-Always turn fuel valve to OFF position prior to storage.
6-Allow the portable generator to cool before cleaning and storage.
7-Change oil .
8-Remove spark plug boot and spark plug. Pour about one teaspoon of engine oil through the
spark plug hole, then slowly pull the recoil starter several times to distribute the oil in the cylinder
Pull recoil slowly until resistance is felt. This will close the valves so no moisture enters the engine
cylinder. Reinstall the spark plug and attach the spark plug boot.
9-Cover the portable generator and store in a clean, dry place out of direct sunlight and away from
any ignition sources.
Any damage or hazards caused by using improper fuel, improperly stored fuel, and/or improperly
formulated stabilizers, are not covered by manufacturer's warranty.
Do not store gasoline from one season to another season.
