pull it out.
Do not remove inner element (6) when doing this.

inner element has not come out of position and is not at an
angle. If is at an angle, insert your hand and push it in straight.

the air cleaner body (7).
5. Remove any dirt or dust that is accumulated to evacuator valve

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.
6. Remove inner element (6), then quickly install the new inner element.
Insert the inner element securely so that it does not move.
7. Push the new outer element (5) 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.
