Air filter
A dirty air filter can reduce engine power, increase fuel consumption, increase CO emissions and make starting
more difficult.
The air filter should be cleaned every 10 hours of use (depending on area of use, dusty areas require more
frequent cleanings).
To clean/replace the air filter:
1. Remove the air filter cover by pressing in the tab on
the bottom of the filter housing and lifting the cover
off. See Figure 2.5.
2.
Pull the filter out. See Figure 2.6.
3.
If the filter is crumbling or brittle, replace the filter.
4.
Wash the air filter with warm soapy water. Let the fil-
ter air dry. DO NOT wring the filter out.
NOTE: Wringing the filter can tear it. Squeeze the filter, but
do not twist it.
5.
Put a 1/4 teaspoon (1.25cc) of oil to the filter and
squeeze it through out the filter.
6.
Insert the filter into air filter housing.
7.
Install the air filter cover.
