4.11 Maintenance procedure
When required
Air Cleaner Element – Install
NOTE
Do not use any damaged gasket or seal or element with
damaged pleats.
Cleaning the element or O-ring after one year has passed
and using them again will cause problems. Replace them
with new parts.
The seal portion on imitation parts lacks precision, and
allows the entry of dust, which leads to damage of the
engine. Do not use such imitation parts.
Do not run the engine with the inner element removed. It will
cause damage to the engine.
1. Check that there is no dirt or oil stuck to the seal portion of
the new element or cleaned element. Wipe off any dirt or oil.
2. When the outer element has been removed, check that the
inner element has not come out of position and is not at an
angle. If at an angle, insert your hand and push it in straight.
3. Push the outer element in straight with your hand when
installing it to the air cleaner body.
If the element is held and rocked lightly up and down and to
the left and right while pushing it in, the element can be
inserted easily.
NOTE
When inserting the element, if the rubber at the tip is swollen
or the outer element is not pushed in straight, and cover (6)
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.
