3.4 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 com-
mercial 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).
Figure 3.4 – Setting the Spark Plug Gap
Sparking can occur if the wire terminal does
not fit firmly on the spark plug terminal end. If
necessary, re-form the wire terminal to obtain a
tight fit.
3.5 FUEL FILTER (GASOLINE ONLY)
Remove and replace the fuel filter (Figure 3.5)
once each year or every 400 hours of operation,
whichever comes first.

3.6 CLEAN SPARK ARRESTOR
The engine exhaust muffler has a spark arrestor
screen. Inspect and clean the screen every 50 hours
of operation or once each year, whichever comes first.
NOTE:
If you use your generator on any forest-covered,
brush-covered or grass-covered unimproved land,
it must equipped with a spark arrestor. The spark
arrestor must be maintained in good condition by
the owner/operator.
Clean and inspect the spark arrestor as follows:
• Remove the screen retaining bracket by removing
the screw.
• Slide the spark arrestor screen out from the tail
pipe.
• Inspect screen and replace if torn, perforated or
otherwise damaged. DO NOT USE a defective
screen. If screen is not damaged, clean it with com-
mercial solvent.
• Replace the screen and the retaining bracket.
