CHECK, CLEAN AND REPLACE AIR CLEANER ELEMENT

When using compressed air for cleaning, dust flies and may cause personal injuly or death. Always wear protective
eyeglasses, dust mask, or other protective equipment.
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 reaction when pulling out the
outer element.
CHECKING
If the internal yellow piston overlaps the red zone (A) on the outside
diameter of dust indicator (1), clean the air cleaner element.
After cleaning, press the reset button to reset the piston.
NOTICE
Do not clean the element until the yellow piston in dust indicator (1)
overlaps the red zone (A) on the outer diameter.
If the element is cleaned frequently before the yellow piston in dust
indicator (1) overlaps the red zone (A) on the outer diameter, the air cleaner
will not be able to provide its expected performance and the cleaning
efficiency will become poor.
In addition, dirt stuck to the element will drop inside the inner element more
frequently during the cleaning operation.
CLEANING OUTER ELEMENT
NOTICE
Before and after cleaning the element, do not leave or keep it in direct
sunlight.
1. Remove 6 holders (2), then remove cover (3) and take out
outer element (4).
