3.6 FUEL FILTER (GASOLINE ONLY)
Remove and replace the fuel filter (Figure 3.5) once
each year or every 100 hours of operation, whichever
comes first.

3.7 SPARK ARRESTOR MUFFLER
If the generator is not equipped with a spark arres-
tor exhaust muffler and is to be used on any forest
covered, brush covered or grass covered unimproved
land, a spark arrestor may need to be installed. The
spark arrestor must be maintained in effective work-
ing order by the vehicle owner/operator.
For assistance in ordering, installing and maintaining
spark arrestor exhaust mufflers, contact the nearest
Authorized Service Dealer.
Exhaust mufflers supplied by the manufacturer are
spark arrestor types. The manufacturer's exhaust
mufflers for recreational vehicle generators do not
have a spark arrestor screen, but are of the more effi-
cient “toroid” or “swirl” type. To remove carbon and
combustion deposits from such mufflers, remove the
plug from the muffler and run the engine for approxi-
mately 15 minutes. Shut down the engine, let the
muffler cool and install the plug.
 Be sure to reinstall the muffler plug 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.
3.8 CLEANING THE GENERATOR
Keep the generator set as clean and dry as possible.
Protect the unit against excessive dust, dirt, corrosive
vapors, road splash, etc. Permitting dirt and mois-
ture to accumulate on generator windings will have
an adverse effect on the insulation resistance of those
windings.
When moisture is allowed to remain in contact with
windings, some of the moisture will be retained in
voids and cracks in the insulation. This causes a
reduced insulation resistance and will eventually
cause problems. Dirt will make the problem worse,
since dirt tends to hold moisture in contact with
windings. Salt (as from sea air) also will worsen the
problem since it tends to absorb moisture from the
air. Salt and moisture, when combined, form a good
electrical conductor.
 Do NOT use a forceful spray of water to clean
the generator. Water will enter the generator
interior and cause problems, and may also con-
taminate the generator fuel system.
3.9 BATTERY MAINTENANCE
All lead-acid batteries will discharge when not in
use. The generator battery should be inspected as
follows:
3.9.1 WEEKLY
Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.
3.9.2 EVERY SIX MONTHS
Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
NOTE:
Servicing of the battery is to be performed or
supervised by personnel knowledgeable of batter-
ies and the required precautions. Keep unauthor-
ized personnel away from batteries.
Damage will result if the battery connections are
made in reverse.
