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.

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.
