properly seated in the air filter case. Never
operate the engine with the air filter ele-

wear and possible engine damage. Addi-
tionally, the fuel injection system would be
affected, resulting in poor engine perfor-
mance and possible overheating.

TIP
The air filter element should be cleaned every 20–
40 hours. It should be cleaned and lubricated
more often if the ATV is operated in extremely
dusty areas. When servicing the air filter element,
be sure to check the air inlet of the air filter case
for obstructions.
