NOTICE
• Be sure to install the air cleaner element facing in the
correct direction. Install so that the bottoms of the air
cleaner element (face where no hole is drilled) (B) and
(C) come to the cover (3) end. If it is installed in wrong
direction, it may cause breakage of the air cleaner ele-
ment or serious damage to the engine.
• When inserting the element into the body, if the rubber
at the tip is swollen or the outer element is not pushed
in straight, and cover (3) is installed by force with
hook (2), there is a danger that the hook and air clean-
er body will be damaged, so be careful when installing.
12. Install the cover (3) according to the following procedure.
1) Check that the O-ring (8) is fitted to the cover (3).
2) Align the cover (3) with the element.
3) Lock the tip of hook (2) on the protrusion of the air
cleaner body.
4) Lock the hooks (2) diagonally, (top and bottom, right
and left) in the same way as when tightening the bolts.
5) Always install the cover (3) so that vacuator (4) faces
the ground (A).
6) When the cover (3) is installed, check that the clear-
ance between the air cleaner body and cover (3) is not
too large. If the clearance is too large, remove the
cover (3), and then install it again.
13. After replacing the element, press the reset button of dust
indicator to return the yellow indicator plate to its original
position.
