CAUTION: Sparking can occur if wire terminal does
not fit firmly over spark plug terminal end. If neces¬
sary, reform wire terminal to obtain a tight fit.

FUEL FILTER
Remove and replace fuel filter (Figure 15) every 100
hours of operation or once each year, whichever
occurs first.

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.
Exhaust 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.
WARNING: Be sure to re-install the plug from the
muffler tightly. Engine vibration could cause a loose
plug to fall out. Without the plug 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.
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.
BATTERY
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
Have the battery state of charge and condition
checked by an automotive service 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.
