Maintenance
Sparking can occur if the wire terminal does
not fit firmly on the spark plug terminal end. If
necessary, re-form the wire terminal to obtain a
tight fit.
3.5 FUEL FILTER
Remove and replace the fuel filter (Figure 3.5) once each year or
every 400 hours of operation, whichever comes first.

CLEAN SPARK ARRESTOR

The engine exhaust muffler has a spark arrestor screen. Inspect
and clean the screen every 50 hours of operation or once each
year, whichever comes first.
If using the generator on any forest-covered, brush-covered or
grass-covered unimproved land, it must equipped with a spark
arrestor. The spark arrestor must be maintained in good condi-
tion by the owner/operator.
Clean and inspect the spark arrestor as follows (Figure 3.6):
• Remove the screen retaining bracket by removing the screw.
• Slide the spark arrestor screen out from the tail pipe.
• Inspect screen and replace if torn, perforated or otherwise
damaged. DO NOT USE a defective screen. If screen is not
damaged, clean it with commercial solvent.
• Replace the screen and the retaining bracket.

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 moisture 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 which is detrimental to the generator.
Do NOT use a forceful spray of water to clean
the generator. Water will enter the generator
interior and cause problems, and may also
contaminate the generator fuel system.

BATTERY MAINTENANCE

All lead-acid batteries will discharge when not in use. The genera-
tor battery should be inspected as follows:
3.8.1 WEEKLY
• Inspect the battery posts and cables for tightness and corro-
sion. Tighten and clean as necessary.
• Check the battery fluid level of unsealed batteries and, if nec-
essary, fill with Distilled Water Only. Do not use tap water in
batteries.
3.8.2 EVERY SIX MONTHS
• Have the state of charge and condition checked. This should be
done with an automotive-type battery hydrometer.
Servicing of the battery is to be performed or supervised by
personnel knowledgeable of batteries and the required precau-
tions. Keep unauthorized personnel away from batteries.
Damage will result if the battery connections are made in
reverse.
