ENGINE AIR CLEANER
Clean and re-oil the foam pre-cleaner every three
months or every 25 hours of operation, whichever
occurs first. Service the foam pre-cleaner more frequently
if you operate the generator in extremely dusty or dirty con­
ditions (Figure 10).
• Turn the two screws counterclockwise to loosen.
• Remove COVER, FOAM PRE-CLEANER and PAPER
FILTER.
• Remove foam pre-cieaner from cover.
• Vt/ash 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 distribute oil (DO NOT TWIST).-
• Install foam pre-cleaner into cover, followed by paper fil­
ter.
• Install cover, foam pre-cleaner and paper filter.
• Tighten the two screws to retain filter in place.
Once each year or every 100 operating hours
(whichever comes first), replace the paper filter. The
new replacement filter must be a flame retardant type.

ENGINE SPARK PLUG
Clean or replace engine spark plug and set gap to
0.030 inch (0.76mm) every 100 hours of operation
(Figure 11). Clean by scraping or wire brushing and
washing with commercial solvent. DO NOT BLAST
CLEAN SPARK PLUG.
Figure 11 — Setting Gap on Spark Plug
CAUTION; Sparking can occur if wire terminal
does not fit firmly over spark plug terminal end. If
necessary, reform wire terminal to obtain a tight fit.
FUEL FILTER
Remove and replace fuel filter (Figure 12) every 100
operating hours or once each year, whichever comes
first.

SPARK ARRESTOR MUFFLER
Exhaust mufflers supplied by Generac are spark
arrestor types. Generac exhaust mufflers for RV gen­
erators do not have a spark arrestor screen, but are
of the more efficient “tproid" 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 materials. This could result in a
fire.
DRIVE BELT
The engine drives the generator rotor by means of a
pulley and drive belt arrangement. The drive belt and
pulleys are warranted for the life of the generator.
Drive belt tension was properly adjusted before the
unit was shipped from the factory. If you suspect that
drive belt tension is incorrect, contact an authorized
service facility.
