ENGINE AIR CLEANER
Clean and re-oil the foam pre-cleaner every three
months or ever 25 hours of operation, whichever
occurs first. Service the foam pre-cleaner more fre­
quently if you operate the generator in extremely dusty
or dirty conditions (Figure 12):
• Turn KNOB counterclockwise to loosen.
• Remove COVER, FOAM PRE-CLEANER and PAPER FIL­
TER.
• Remove foam pre-cleaner from cover
• Wash foam pre-cleaner in liquid detergent and water.
• Wrap foam pre-cleaner in a cloth and squeeze dry.
• Saturate foam pre-cleaner in engine oil. Squeeze to
remove excess oil and to distribute oil.
• Install foam pre-cleaner into cover, followed by paper filter.
Tabs at edges of paper filter must lock into slots on cover.
Once each year or every 100 operating hours
(whichever comes first), replace the paper filter. The
new replacement filter must be a flame retardent type.

CLEAN AIR INTAKE SCREEN
Clean all foreign material from the air intake screen

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
arrestor 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.
