• Change the engine oil after the first 25 hours of 

operation (after the 25-hour break-in period, see 
Section 2.8.5). 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:

1.  Run the engine until it is thoroughly warmed up 

(at least five minutes) then shut OFF the engine.

2.  With the engine still warm from running, remove 

the oil drain plug (Figure 3.1). Drain the oil into 
a suitable container.

3.  After the oil has drained, replace the oil drain 

plug. (If only changing the oil, go to step 7.)

4.  With the oil drained, remove the old oil filter by 

turning it counterclockwise (Figure 3.2).

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 fill crankcase with the 

proper type and amount of recommended oil 
(see Section 1.6.2). The engine crankcase can 
hold about 1.8 liters or 1.9 quarts with oil fil-
ter change. DO NOT FILL ABOVE THE “FULL” 
MARK.

8.  Install and tighten the dipstick before operating 

the engine.

9.  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.

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 3.3):

1.  Turn the knob 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. Tabs at edges of paper 
filter must lock into slots on cover.

8.  Install the cover, foam precleaner and paper fil-

ter.

9.  Replace knob to retain the filter in place.
