WARNING
• If inspection, cleaning, or maintenance is performed while the engine is running, dust enters into
the engine and damages it. Be sure to stop the engine before performing these works.
• When using compressed air, there is a danger that dirt may scatter and cause personal injury. Al-
ways wear protective equipment such as protective eyeglasses and dust mask.
• When working in high places or where the foothold is poor, be careful not to fall because of the re-
action when pulling out the element.
METHOD OF CHECKING
NOTICE
Do not clean the element before the yellow piston of dust
indicator (1) laps over peripheral red zone (A) or before air
cleaner clogging caution lamp (B) lights up.
If the element is cleaned frequently before the yellow pis-
ton of dust indicator (1) laps over the peripheral red zone
(A) or before air cleaner clogging caution lamp (B) lights
up, the air cleaner cannot display its normal performance
and the cleaning effect decreases.
In addition, the frequency of dust stuck to the element fall-
ing inside the inner element during the cleaning operation
will increase.
