INSPECTION AND MAINTENANCE

CAUTION

A torn air filter could damage your ATV.

Dirt and dust may get inside of the engine if the element is torn.

Examine carefully the element for tears before and after cleaning it.
Replace the element with a new one if it is torn.

CAUTION

Failing to position the air cleaner element properly could damage your

ATV.

Air will bypass the air cleaner element if the element is not positioned

properly. This will cause the engine parts to wear more rapidly.

Be sure to position the air cleaner element properly.
