FUEL FILTER
Remove and replace fuel filter (Figure 14) every 100 hours of
operation or once each year, whichever comes first.

SPARK ARRESTOR MUFFLER
If the generator is not equipped with a spark arrestor exhaust
muffler and is to be used on any forest covered, brush cov­
ered 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 arrestor
types. Generac exhaust muffler for recreational vehicle gen­
erators do not have a spark arrestor screen, but are of the more
efficient “toroid” or “swirl” type. To remove carbon and com­
bustion deposits from such mufflers, remove the PLUG from
the 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 insulation resistance
of those windings.
Moisture that is allowed to remain in contact with windings wiii
be retained in voids and cracks of the windings. Dirt makes
the probiem worse, since it tends to hold the moisture into con­
tact with the windings. Salt, as from sea air, worsens the
probiem since it tends to absorb moisture from the air. The
combination of sait and moisture makes a good electricai con­
ductor.
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 contam­
inate the generator fuel system.
BAHERY
Ail lead-acid storage batteries wili discharge when not in use.
The generator battery shouid be inspected as follows:
ONCE WEEKLY
Inspect battery posts and cables for tightness, corrosion.
Ciean and/or tighten as needed.
Aiso check battery fluid levei, and, if necessary, fiil with DIS­
TILLED WATER ONLY. DO NOT USE TAP WATER IN
BAHERY.
EVERY SIX MONTHS
Have battery state of charge and condition checked. This
should be done with automotive type battery hydrometer.
DANGER; Storage batteries give off explosive
hydrogen gas. This gas can form an explosive
mixture around the battery for several hours after
charging. The slightest spailc can ignite the gas
and cause an explosion. Such an explosion can
shatter the battery and cause blindness or o№er
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok­
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
