STORAGE
If you are going to store your generator for more than
30 days, use the following information as a guide to
prepare the generator for storage.
Never store generator with
fuel in the tank indoors or
in enclosed, poorly ventilated areas, where
fumes can reach an open flame, spark or pilot
light as on a furnace, water heater, clothes
dryer or other gas appliances.
Engine Preparation
• Add fuel stabilizer to fuel tank to minimize the
formation of fuel gum deposits during storage.
• Run engine at least 10 minutes after adding
stabilizer to allow it to enter the fuel system.
• Disconnect the spark plug wire and remove the
spark plug.
• Add one teaspoon of oil through the spark plug
hole.
• Place rag over spark plug hole and pull the recoil a
few times to lubricate the combustion chamber.
Replace the spark plug, but do not connect the
spark plug wire.
NOTE: If a fuel stabilizer is not used, all gasoline must
be drained from the tank and carburetor to prevent gum
deposits from forming on these parts and causing pos-
sible malfunction of the engine.
Generator
• Clean the generator as outlined in the Generator
Maintenance paragraph on page 18.
• Check that cooling air slots and openings on
generator are open and unobstructed.
Battery
• Store battery as described by the battery manu-
facturer.
NOTE: After storing battery for a long period of time it
may lose it's charge. If the battery loses it's charge,
manually start the engine with the battery connected.
The engine will recharge the battery as it runs.
CARBURETOR
The carburetor of your generator is pre-set at the fac-
tory. The carburetor should not be tampered with. If your
generator is used at an altitude in excess of 4000 feet
performance may be affected. If so consult with your
nearest Craftsman Service Center regarding high altitude
set changes.
GOVERNOR
Your engine governor maintains the constant operating
speed of your generator. DO NOT tamper with the en-
gine governor which is factory set for proper engine
speed.
Low engine speeds impose a
heavy load on the engine and
when sufficient power is not available the engine
life could be shortened.
SERVICE ADJUSTMENTS
Over-speeding your engine above factory high speed set-
ting can be dangerous and could possibly cause per-
sonal injury or property damage. If you believe the en-
gine is running too fast or slow, take your generator to a
Authorized Craftsman Service Center for repair and ad-
justment.
GFCI receptacle (Ground Fault Circuit
Interrupter)
For maximum protection against electrical shock the
GFCI should be tested monthly.
To test:
1. Depress the TEST button. The RESET button
should extend. If the RESET button does not
extend, notify a Authorized Service Center.
2. To restore power, depress the RESET button firmly
into the GFCI unit until an audible click is heard. If
reset properly, the RESET button is flush with the
surface of the test button. When the button stays
in, the power is ON.
