AIR FILTER
1. The air filter element should be cleaned because a
clogged air cleaner can cause poor engine starting,
lack of power and shorten engine life substantially.
2. To clean or replace air filter loosen the wing nut on the
air filter housing (Figure 15), remove the cover and
take out air filter cartridge. If only cleaning of the air
filter is desired blow through the air filter cartridge from
the inside, moving a jet of dry compressed air up and
down until all dust is removed.
