METHOD FOR REPLACING ELEMENT
1.
Open the engine side cover on the left side of the ma-
chine.
2.
Undo latches (2) (6 places) and remove cover (3).
3.
Hold the outer element (4), rock it lightly up and down and
to the right and left, and pull the element out.
NOTICE
Do not use a screwdriver or other tool.
4.
Wipe off or brush off the dirt stuck to the inside of the air
cleaner body (6) and cover (3).
5.
Remove inner element (5), then quickly install the new in-
ner element.
Install the inner element (5) securely so that it does not
move.
NOTICE
• Do not clean and reuse inner element (5). When re-
placing outer element (4), replace the inner ele-
ment with new one as well.
• If the outer element (4) and cover (3) are installed
while the inner element (5) is not installed proper-
ly, the outer element (4) may be damaged.
• The sealing portion of the improper part lacks pre-
cision, and allows the entry of dust, which leads to
damage of the engine. Do not use such improper
part.
6.
Push new outer element (4) in straight with your hand into the air cleaner body.
Hold the outer element (4), and rock it lightly up and down and to the right and left while pushing it in, the
outer element can be inserted easily.
NOTICE
When inserting the element into the body, if the rubber at the tip is swollen or outer element (4) is
not pushed in straight, and cover (3) is installed by force with hook (2), there is a danger that the
hook and air cleaner body may be damaged, so be careful when installing.
