3.1 CHECKING THE ENGINE OIL
LEVEL
For oil capacities and requirements, see “Engine Oil
Requirements”. Check the engine crankcase oil level
at least every eight hours of operation, or before each
use. To check the engine oil level, proceed as follows
(see Figure 3.1):
1. Be sure the generator is as level as possible.
2. Remove the dipstick and wipe it dry with a clean,
lint-free cloth.
3. Install and tighten the dipstick cap; then, remove
it again. The oil level should be at the dipstick
“Full” mark.
4. If necessary, remove the oil fill cap on the rocker
cover and slowly add oil until it reaches the dip-
stick “Full” mark. DO NOT FILL ABOVE THE
“FULL” MARK.
Never operate the engine with the oil level
below the “Add” mark on the dipstick. Doing
this could damage the engine.
5. Install and tighten the oil fill cap and the dipstick
before operating the engine.
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 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 rec-
ommended oil (see “Engine Oil Requirements”).
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.
