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.

Once each year or every 100 hours of operation 
(whichever comes first), clean or replace the paper 
filter. The new replacement filter must be flame 
retardant. Service the paper filter more frequently if 
operating the generator in extremely dusty or dirty 
conditions. Use the following procedure (Figure 3.2):

1.  Follow steps 1-3 in "Cleaning the Foam Precleaner"; 

service the foam precleaner if necessary.

2.  Remove the paper filter.
3.  Clean the air filter by tapping it gently on a solid 

surface. If the filter is too dirty, replace it with a 
new one. Dispose of the old filter properly.

4.  Clean the air cleaner cover then reassemble fol-

lowing steps 7-9 in section "Cleaning the Foam 
Precleaner".

Clean all foreign material from the air intake (Figure 
3.3) at least once every 100 hours of operation. Clean 
more often if necessary.

Inspect the area around the generator exhaust muf-
fler periodically and remove all grass, leaves, dirt, 
etc., from this area.

Clean the spark plug and reset the spark plug gap 
every 100 hours of operation.

1.  Clean the area around the base of the spark plug 

to keep dirt and debris out of the engine. Remove 
the spark plug and check the condition. Replace 
the spark plug if worn or if reuse is question-
able.

2.  Clean spark plug by scraping or washing using a 

wire brush and commercial solvent. Do not blast 
the spark plug to clean.

3.  Check the spark plug gap using a wire feeler 

gauge. Adjust the gap to 0.030 inch (0.76 mm) 
by carefully bending the ground electrode (Figure 
3.4).
