8. Reinstall the element to the element
guide.
9. Reinstall the element assembly and parts
removed for access.
NOTE:
The air filter element should be cleaned every
20 ~ 40 hours. It should be cleaned and lubri-
cated more often if the machine is operated in
extremely dusty areas. Each time filter element
maintenance is performed, check the air inlet
to the filter case for obstructions. Check the air
cleaner rubber joint to the carburetor and man-
ifold fittings for an air-tight seal. Tighten all fit-
tings securely to avoid the possibility of
unfiltered air entering the engine.
CAUTION:
Never operate the engine with the air filter el-
ement removed. This will allow unfiltered air
to enter, causing rapid engine wear and possi-
ble engine damage. Additionally, operation
without the filter element will affect carbure-
tor jetting with subsequent poor performance
and possible engine overheating.
