section 3 – Maintenance
recreational vehicle generator
• Change the engine oil filter after the first 25 hours
of operation, and every 100 operating hours there-
after.
To change the oil and/or oil filter, proceed as
follows (see Figure 3.1):
1. Run the engine until it is thoroughly warmed up
(at least five minutes) then shut OFF the engine.
2. Immediately after the engine shuts OFF, pull the
oil drain cover free of the base. Remove the plug
from the tube with a 5/16” allen wrench and drain
the oil into a suitable container. Loosening the oil
fill cap will allow the crankcase to drain faster.
3. After the oil has drained, replace the plug onto
the end of the oil drain tube. Retain the cover in
the base.
4. With the oil drained, remove the old oil filter by
turning it counterclockwise. Place a towel under-
neath to catch excess oil.
5. Apply a light coating of clean engine oil to the gas-
ket of the new filter. Fill the filter until saturated
with clean oil.
6. Screw the new filter on by hand until its gasket
lightly contacts the oil filter adapter. Then, tighten
the filter an additional 3/4 to one turn.
7. Remove the dipstick and wipe it dry with a clean,
lint-free cloth. This will be used later to check the
oil level.
8. Remove the oil fill cap on the oil fill tube and
slowly add the proper type and amount of recom-
mended oil (see Section 1.5.4). Periodically use
the dipstick to check the oil level and continue to
fill the crankcase until the oil reaches the dipstick
“Full” mark. DO NOT FILL ABOVE THE “FULL”
MARK.
9. Install and tighten the oil fill cap and the dipstick
before operating the engine.
10. Start the engine and check for leaks.
NOTE:
Check the oil level and fill to the “FuLL” mark
after checking for leaks. The filter will retain some
oil.
3.3 MaIntaInIng the engIne
aIr cleaner
3.3.1 cleanIng the FoaM precleaner
Clean and re-oil the foam precleaner every three
months or every 25 hours of operation, whichever
occurs first. Service the foam precleaner more fre-
quently if operating the generator in extremely dusty
or dirty conditions. Use the following procedure
(Figure 3.2):
1. Turn the two screws counterclockwise to loosen.
2. Remove the cover, foam precleaner and paper filter.

3. Remove the foam precleaner from the cover.
4. Wash the foam precleaner in liquid detergent and
water.
5. Wrap the foam precleaner in a clean cloth and
gently squeeze it dry.
6. Saturate the foam precleaner in clean engine
oil. Gently squeeze it in a clean cloth to remove
excess oil and to distribute oil (DO NOT TWIST).
7. Install the foam precleaner into the cover, fol-
lowed by the paper filter.
8. Install the cover, foam precleaner and paper filter.
9. Tighten the two screws to retain the filter in place.

3.3.2 cleanIng or replacIng the paper
FIlter
Once each year or every 100 hours of operation
(whichever comes first), clean or replace the paper
filter. The new replacement filter must be flame
retardant. Service the paper filter more frequently if
operating the generator in extremely dusty or dirty
conditions. Use the following procedure (Figure 3.2):
1. Follow steps 1-3 in Section 3.3.1; service the
foam precleaner if necessary.
2. Remove the paper filter.
3. Clean the air filter by tapping it gently on a solid
surface. If the filter is too dirty, replace it with a
new one. Dispose of the old filter properly.
4. Clean the air cleaner cover then reassemble
following steps 7-9 in Section 3.3.1.
3.4 clean aIr Intake
Clean all foreign material from the air intake (Figure
3.3) at least once every 100 hours of operation. Clean
more often if necessary.
Inspect the area around the generator exhaust muf-
fler periodically and remove all grass, leaves, dirt,
etc., from this area.
