3.7 GENERAL
The generatorshould 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.
_t Allow unit to cool entirely before storage.
3.8 LONG TERM STORAGE
It is important to prevent gum depositsfrom forming in essential
fuel system parts such as the carburetor,fuel hoseor tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separationand formation of acids during storage. Acidic
gas can damagethe fuel system of an enginewhile in storage.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer,as follows:
* Add a qualitygasolinestabilizerto the fuel per the manufacturers
specifications,and run the unit for 10-15 minutes.
* After enginecools down, removeall gasolinefrom the fuel tank.
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.
* After engine cools down, drain oil from engine. Refill with
recommendedgrade.
* Removespark 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. A fogging agent can also be used in the place
of oil.
A CAUTION!
_11 void spray from spark plug hole when
cranking engine.
* Install and tighten spark plug. Do not connect spark plug wire.
* Cleanthe generatorouter surfaces. Checkthat cooling air slots
and openings on generatorare open and unobstructed.
* Storethe unit in a clean, dry place.
3.9 OTHER STORAGE TiPS
* Do not store gasolinefrom one season to another.
* Replacethe gasolinecan 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 indoorsand cover it to give protection
from dust and dirt. BESURETO EMPTYTIlE FUELTANK.
* If it is not practical to empty the fuel tank and the unit is to
be stored for some time, use a commercially availablefuel
stabilizer added to the gasoline to increase the life of the
gasoline.Run the unitfor 10=15minutes, turn off the fuel valve
and allow to run until engine stops from lack of fuel.
* Cover the unit with a suitable protective cover that does not
retainmoisture.
_t NEVER cover the generator while engine and
exhaust areas are warm,
