MAINTENANCE MAINTENANCE
NOTICE
If small holes or thinner parts are found on the element when it is checked
with an electric bulb after cleaning and drying, replace the element.
When cleaning the element, do not hit it or beat it against something.
Do not use an element whose folds or gasket or seal are damaged.
6. Remove the cloth or tape cover installed in Step 3.
7. 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.
NOTICE
The inner element must not be cleaned and used again. When replacing
the outer element, replace the inner element at the same time.
If the inner element is not installed properly and the outer element and
cover are installed, there is danger that the outer element will be
damaged.
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.
8. Push the outer element in straight with your hand when
installing it to the air cleaner body.
If the outer element is held and rocked lightly up and down and
to the left and right while pushing it in, the outer element can be
inserted easily.
1) Check that the inner element is not loose. If it is loose,
insert it securely.
2) If the yellow piston in dust indicator (1) overlaps the red
zone (A) on the outer diameter immediately after the outer
element is cleaned, replace both the inner and outer
elements.
