Cleaning the air filter element

The air filter element should be cleaned every
20–40 hours of engine operation. It should be
cleaned and lubricated more often if the vehi-
cle is operated in extremely dusty areas. Each
time air filter maintenance is performed,
check the air inlet to the air filter case for ob-
structions. Also check the air filter element
rubber joint to the throttle body and manifold
