CHECK, CLEAN AND REPLACE AIR CLEANER ELEMENT
WARNING
q
Always wear protective glasses, dust mask, or other protective equipment.
q
When removing the air cleaner element from the air cleaner body, it is dangerous to pull it out by force.
When working at high places or where the foothold is poor, be careful not to fall because of the reac-
tion when pulling out the outer element.
CHECKING
When the yellow piston inside red zone (A) of the dust indicator
(1) overlaps the red zone, clean the air cleaner element. After
cleaning, press the reset button.
NOTICE
Always wait for the yellow piston in the dust indicator to
overlap the red zone on the outside before cleaning the
element.
If the element is cleaned frequently before the yellow pis-
ton in the dust indicator overlaps the red zone on the out-
side, the air cleaner will be unable to display its normal
performance and the cleaning effect will become poor.
In addition, the frequency of dust stuck to the element fall-
ing inside the inner element during the cleaning operation
will increase.
CLEANING OR REPLACING OUTER ELEMENT
NOTICE
Before and after cleaning the element, do not leave or keep
it in direct sunlight.
1. Remove 6 hooks (2), then remove cover (3).
Remove outer element.
2. Hold the outer element, rock it lightly up and down and to
the left and right, and rotate the element to the left and right
to pull it out.
NOTICE
q
Never remove the inner element. It will allow dirt to
enter and cause failure of the engine.
q
Do not use a screwdriver or other tool.
3. After removing the outer element, cover the air connector
inside the air cleaner body with a clean cloth or tape to pre-
vent dirt or dust from entering.
