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.
2. Start and run engine until engine stops from lack of fuel.
3. After the engine cools down, drain oil from crankcase. Refill with
recommended grade.
4. 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.
5. Remove the black battery cable from the battery post indicated by a
negative, NEG or (-) and attach to frame ground.
Avoid spray from spark plug holes when cranking

engine.
6. Install and tighten spark plugs. Do not connect spark plug wires.
7. Clean the generator outer surfaces. Check that cooling air slots and
openings on generator are open and unobstructed.
8. Store the unit in a clean, dry place.

3.10 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 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/or

exhaust area are warm.
