MAINTENANCE PROCEDURE
4.
Clean the dust sticking inside the air cleaner body (7) and
on the cover (3) by using a clean cloth or brush.
5.
If any dust is attached to the vacuator valve (4) installed to
the cover (3), remove it.
NOTICE
• Do not clean and reuse the inner element. When replacing the outer element, replace the inner ele-
ment with a new one at the same time.
• If the outer element and cover are installed while the inner element is not installed properly, the out-
er element may be damaged.
• The sealing portion of the improper part lacks precision, and allows the entry of dust, which leads
to damage of the engine. Do not use such improper part.
6.
Remove the inner element (6), then install the new inner element immediately.
Install the inner element securely so that it does not move.
7.
Push in the new outer element (5) straight with your hand into the air cleaner body.
Hold the element, and rock it lightly up and down and to the right and left while pushing it in, the element
can be inserted easily.
8.
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.
