Air filter
A dirty air filter can reduce engine power, increase fuel
consumption and make starting more difficult. The air filter
should be cleaned every 100 hours and replaced every
200 hours of use.
To check the air filter:
1. Swing open the air filter cover located at the back of
the engine. See Figure 8.3.
2. Unhook the wire clamp that holds the air filter in
place. See Figure 8.4.
3. Remove the air filter.
4. If a foam air pre-cleaner is dirty, but not in bad of con-
dition, it can be cleaned and reused. The paper
pleated filters can be shaken or lightly tapped to free
the debris from the filter. See Figure 8.5.
5. Foam pre-filters can be washed in warm soapy
water.
NOTE: When drying a foam filter either squeeze it inside
of a paper towel or let it air dry. DO NOT wring it
because the filter will tear.
6. Before installing any foam filter, after it has been
washed, it needs to be free of moisture.
NOTE: Do not oil the foam pre-filter. The paper filer will
absorb the oil and it will become plugged.
7. The air filter can be cleaned by lightly tapping it on a
hard surface.
NOTE: Never blow compressed air through a paper air fil-
ter. The force of the air moving through the air filter
will damage the paper fibers that remove the
microscopic particles of dirt from the air.
NOTE: The paper element should be white in color. If the
dirt does not come out of the filter with gentle tap-
ping, replace the filter.
8. Install the filter by reversing previous steps.
