3.7 GENERAL
The generator should be started at least once every seven days
and be allowed to run at least 30 minutes. If this cannot be done
and you must store the unit for more than 30 days, use the
following information as a guide to prepare it for storage.
ƷƸ DANGER! 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.
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:
• Remove all gasoline from the fuel tank.
ƷƸDANGER! Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool. Do not
smoke.
• Start and run engine until engine stops from lack of fuel.
• While engine is still warm, drain oil from crankcase. Refill with
recommended grade.
• Remove spark plugs and pour about 1/2 ounce
(15 ml) of engine oil into the cylinders. Cover spark plug hole
with rag. Press the “Start” button and allow engine to crank for
2 seconds. Then press the “Stop” button.
ƽCAUTION! Avoid spray from spark plug holes when cranking
engine.
• Install and tighten spark plugs. Do not connect spark plug
wires.
• Clean the generator outer surfaces. Check that cooling air
slots and openings on generator are open and unobstructed.
• Store the unit in a clean, dry place.
3.9 OTHER STORAGE TIPS:
• Do not store gasoline from one season to another.
• Replace your gasoline can if your can starts to rust. Rust
and/or dirt in your gasoline will cause problems with the
carburetor and fuel system.
• If possible, store your unit indoors 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 your unit with a suitable protective cover that does not
retain moisture.
ƽ DANGER NEVER cover your generator while engine and
exhaust area are warm.
