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 fil-

3.3.2 CLEANING OR REPLACING
THE PAPER FILTER
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 the "Cleaning the Foam
Precleaner" section; 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
following steps 7-9 in the "Cleaning the Foam
Precleaner" section.
3.4 CLEAN AIR INTAKE
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.

3.5 CHECKING THE ENGINE
SPARK PLUG
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. Clean
by scraping or washing using a wire brush and
commercial solvent. Do not blast the spark plug
to clean.
2. Remove the spark plug and check the condition.
Replace the spark plug if worn or if reuse is ques-
tionable.
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).
 Sparking can occur if the wire terminal does not
fit firmly on the spark plug terminal end. If nec-
essary, re-form the wire terminal to obtain a
tight fit.
