NOTICE
Do not use an element whose folds or gasket or seal are damaged.
If the element or O-ring are cleaned and used again after they have been used for more than 1 year, it will cause problems. Do
not use them again.

dirt or oil.
11. 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.
NOTICE
Be sure to install the air cleaner element facing in the correct direction.
Install so that the bottom of the air cleaner element cylinder (face where no
hole is drilled) (B), (C) is at cover (3) end. If the direction of installation is
mistaken, there is danger that it will cause breakage of the air cleaner
element or serious damage to the engine.
