MAINTENANCE PROCEDURE

When inserting the element, if the rubber at the tip is swol-

len or the outer element is not pushed in straight, and

cover (3) is assembled by force to hook (2), there is danger

that the hook and air cleaner body may be damaged, so be

careful when assembling.

12. Install cover (3) as follows.

1) Align cover (3) with the element.

2) Hook the tip of hook (2) to the protruding part of the air cleaner body and lock it in position.

3) When locking hooks (2) in position, apply the hooks in turn on opposite sides (top, bottom, left, right) in the

same way as when tightening bolts.

4) Always install cover (3) so that the evacuator (4) is facing the ground (A).

5) When cover (3) is installed, check that the clearance between the air cleaner body and cover (3) is not too

large. If it is too large, install again.
