The air filter must be cleaned after every 50 hours of
use or 3 months (frequency should be increased if
generator is operated in a dusty environment).
1. Turn off the generator and let it cool for several
minutes if it’s been running.
2. Move the generator to a flat, level surface.
3. Release the latches at the top and bottom of the
air filter assembly (see Figure 34).

filter assembly noting its orientation with the choke
function decal at the top. Clean the air filter cover
with a rag and place it aside.

5. Remove the two foam air filter elements while
taking care to note their positions (see Figures
35 and 36). The black foam air filter element is
the coarse stage and must be re-installed at the
front directly underneath the air filter cover. The
grey foam air filter element is the fine stage and
must be re-installed at the back of the air filter
assembly.

of household detergent and warm water or
alternatively in non-flammable solvent. Slowly
squeeze each foam element separately in the
liquid for a thorough cleaning action. Then remove
each foam and squeeze out the liquid.
