The air filter element should be cleaned every
2040 hours. It should be cleaned and lubri-
cated more often if the vehicle is operated in
extremely dusty areas. Each time air filter ele-
ment maintenance is performed, check the air
inlet to the air filter case for obstructions.
Check the air filter element rubber joint to the
throttle body and manifold fittings for an air-
tight seal. Tighten all fittings securely to avoid
the possibility of unfiltered air entering the en-
gine.
NOTICE
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 air filter element will af-
fect the fuel injection system with
subsequent poor performance and possi-
ble engine overheating.
