ement.
10. Install the air filter assembly and parts re-
moved for access.
NOTE:
_
The air filter element should be cleaned every
2040 hours. It should be cleaned 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 manifold fit-
tings for an airtight seal. Tighten all fittings se-
curely to avoid the possibility of unfiltered air
entering the engine.
_
CAUTION:
_
Never operate the engine with the air filter
element removed. This will allow unfiltered
air to enter, causing rapid engine wear and
possible engine damage. Additionally, op-
eration without the filter element will affect
carburetor jetting with subsequent poor
performance and possible engine over-
heating.
