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.



5.  Install and tighten the oil fill cap and the dipstick 

before operating the engine.

• Change the engine oil after the first 25 hours of 

operation (after the 25-hour break-in period sec-
tion). Thereafter, change the oil every 100 oper-
ating 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 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 Specifications). 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.

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.
