SERVICE PROCEDURE
REPLACING ELEMENT
1. Open cover on the right side of the machine.
2. Remove 6 holders (2), then remove cover(3).
3. Hold the outer element (4), move it carefully up and down and
to the left and right, and rotate the element to the left and right
while pulling it out.
4. Use a brush or cloth to remove all the dirt stuck to cover (3) and
the inside of air cleaner body (6).
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 improper parts lacks precision, and allows the entry of dust, which leads to damage of the engine. Do not
use such improper parts.
5. Remove inner element (5), then quickly install the new inner
element.
Push the inner element in properly and check that it is fitted
securely.
6. Push new outer element (4) straight into the air cleaner body
with your hand.
If you hold the element and move it carefully up and down and
to the left and right, it is easier to insert the element.
7. Replace O-ring (7) for cover (3) with new one.
