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 the dust indicator (1) laps over the peripheral red
zone.
If the element is cleaned frequently before the yellow piston of the dust indicator (1) laps over the pe-
ripheral red zone, the air cleaner cannot display its normal performance and the cleaning effect decreas-
es.
In addition, during the cleaning operation, more dirt stuck to the element will fall inside the inner ele-
ment.
