MAINTENANCE AND SERVICING
8. Pull out the primary fi lter element (A).
IMPORTANT:
Be extremely careful with the dirty element until
it is completely out of the housing. Accidentally
bumping it while still inside may cause dirt
and dust to contaminate the clean side of
fi lter
housing.
9. If necessary, also change the secondary fi lter (B).
Refer to Replacing Secondary Air Filter, page 284 .
IMPORTANT:
• Do NOT remove the secondary fi lter unless it
needs replacing. It must never be cleaned.
• Replace secondary fi lter annually or after every
third primary fi lter change, even if it looks clean.
• If the secondary fi lter looks dirty, a further
inspection will be required.
• Examine fi lter canister for cracks and replace
as necessary.
• Ensure canister retaining latches are secure.

IMPORTANT:
Clean the inside of the housing and cover carefully. Dirt left in the air cleaner housing may be harmful to
your engine.
• Use a clean, water-dampened cloth to wipe every surface clean.
• Check it visually to make sure it is clean before putting in a new element.
• Always clean the gasket sealing surfaces of the housing. An improper gasket seal is one of the most common
causes of engine contamination.
• Make sure that all hardened dirt ridges are completely removed wherever fi lter gaskets contact the cleaner
housing.
Check for uneven dirt patterns on your old element. Your old element is a valuable clue to potential dust
leakage or gasket sealing problems.
• A pattern on the element clean side is a sign that the old element was not fi rmly sealed or that a dust leak exists.
• Make certain the cause of that leak is identi fi ed and recti fi ed before replacing the element.
• Recheck to see if the sealing surface in the housing is clean.
