3.7 GENERAL
The generator should be started at least once every 30 days and
be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
information as a guide to prepare it for storage.
NEVER store engine with fuel in tank indoors
or in enclosed, poorly ventilated areas where
fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes
dryer or other gas appliance.
Allow unit to cool entirely before storage.
3.8 LONG TERM STORAGE
It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can 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.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:
1. Remove all gasoline from the fuel tank.

Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke in the vicinity or light a cigarette.
2. Start and run engine until engine stops from lack of fuel
3. Allow the engine to cool to the touch and then drain the oil
from the crankcase. Refill with the recommended grade.
4. Remove spark plug and pour about 1/2 ounce (15 ml) of
engine oil into the cylinder. Cover spark plug hole with rag. Pull
the recoil starter a couple times to lubricate the piston rings
and cylinder bore.
Avoid spray from the spark plug hole when
cranking engine.
5. Install and tighten the spark plug. Do not connect the spark
plug wire.
6. Clean the generator outer surfaces. Check that cooling air
slots and openings on generator are open and unobstructed.
7. Store the unit in a clean, dry place.
3.9 OTHER STORAGE TIPS
• Do not store gasoline from one season to another.
• Replace the gasoline can if it starts to rust. Rust and/or dirt in
the gasoline will cause problems with the carburetor and fuel
system.
• If possible, store the unit indoors, in a garage or shed, and
cover it to give protection from dust and dirt. BE SURE TO
EMPTY THE FUEL TANK.
• If it is not practical to empty the fuel tank and the unit is to
be stored for some time, use a commercially available fuel
stabilizer added to the gasoline to increase the life of the
gasoline.
• Cover the unit with a suitable protective cover that does not
retain moisture.
NEVER cover the generator while engine and
exhaust area are warm. Allow unit to cool
entirely.
