3.2 CHANGING THE ENGINE OIL
AND/OR OIL FILTER
Change the engine oil after the first 25 hours of
operation. Thereafter, change the oil every 100
operating hours. Change the oil more frequently if
operating consistently under heavy load or at high
ambient temperatures.
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 fol-
lows (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 hose free of its retaining clip. Remove
the cap from the hose 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 cap onto the
end of the oil drain hose. Retain the hose in the
clip.
4. With the oil drained, remove the old oil filter by
turning it counterclockwise.
5. Apply a light coating of clean engine oil to the
gasket of the new filter.
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 rocker cover
and slowly add the proper type and amount
of recommended oil (see section "Engine Oil
Requirements"). Periodically use the dipstick to
check the oil level and continue to fill the crank-
case 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.
