MAINTENANCE PROCEDURE
10. After cleaning, illuminate the inside of the element with an
electric bulb to check.
If any hole or thin place is found, replace the inner and out-
er elements.
11. Remove the cover of cloth or tape attached to inner ele-
ment (6).
NOTICE
Do not use the element with damaged pleats or a damaged gasket or seal.
If the element and O-ring are cleaned and used again after they are used for more than one year, it
will cause problems. Do not use them again.
12. Check the seal of the cleaned or new element for sticking of dusts and oil and wipe them off, if any.
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 may be damaged, so be careful when instal-
ling.
13. Push the outer element straight into the air cleaner body with your hand.
Hold the outer element, and rock it lightly up and down and to the right and left while pushing it in, the outer
element can be inserted easily.
14. Install the cover (3) according to the following procedure.
1)
Check that the O-ring (8) is fitted to the cover (3).
