not fit firmly over spark plug terminal end. If neces­

sary, reform wire terminal to obtain a tight fit.

hours of operation or once each year, whichever
occurs first.

WARNING: Be sure to re-install the plug from the

muffler tightly. Engine vibration couid cause a ioose

piug to fail out. Without the piug in place, hot engine

exhaust is directed out the opening. This hot

exhaust, depending on the installation, could be

directed to areas not able to withstand the extreme
heat such as wooden floor boards or other flammable
material. This could result in a fire.

CLEANING THE GENERATOR

Keep your generator set as clean and dry as possible.
Dirt and moisture that are permitted to accumulate on
electrical windings have an adverse affect on the insu­
lation resistance of those windings.

Moisture that is allowed to remain in contact with wind­
ings will be retained in voids and cracks of the wind­
ings. Dirt makes the problem worse, since it tends to
hold the moisture into contact with the windings. Salt,
as from sea air, worsens the problem since it tends to
absorb moisture from the air. The combination of salt
and moisture makes a good electrical conductor.

SPARK ARRESTOR MUFFLER

If the generator is not equipped with a spark arrestor

exhaust muffler and is to be used on any forest cov­
ered, brush covered or grass covered unimproved

land, you may have to install a spark arrestor. The

spark arrestor must be maintained in effective working
order by the vehicle owner/operator.

For assistance in ordering, installing and maintaining

spark arrestor exhaust mufflers, contact your nearest
authorized service facility.

Fxhaust mufflers supplied by Generac are spark
a.restor types. Generac exhaust mufflers for IM gener­

ators do not have a spark arrestor screen, but are of
the more efficient “toriod” or “swirl” type. To remove
carbon and combustion deposits from such mufflers,
remove the PLUG from muffler and run engine for
about 15 minutes. Shut engine down, let the muffler
cool and Install the plug.

CAUTION! Do NOT use a forceful spray of water to
clean the generator. Water will enter the generator

interior and cause problems, and may also contami­
nate the generator fuel system.

BAHERY

All lead-acid storage batteries will discharge when not

in use. Inspect the generator battery as follows:

■ ONCE WEEKLY_______________________

Inspect battery posts and cables for tightness, corro­

sion. Clean and/or tighten as necessary.

Also check battery fluid level, and, if necessary, fill with

DISTILLED WATER ONLY. DO NOT USE TAP

WATER IN BATTERY.

■ EVERY SIX MONTHS

Flave the battery state of charge and condition

checked by an automotive service '

rg<

facility. This should

be done with an automotive type battery hydrometer.

DANGER: Storage batteries give off explosive

hydrogen gas. This gas can form an explosive mix­
ture around the battery for several hours after

charging. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shatter
the battery and cause blindness or other injury.

Any area that houses a storage battery must be

properly ventilated. Do not allow smoking, open

flame, sparks or any spark producing tools or

equipment near the battery.
