METHOD FOR CHECKING, CLEANING AND REPLACING AIR CLEANER

• 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. Always 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 reaction when pulling out the element.

Do not clean the element before the air cleaner clogging caution lamp lights up or the yellow piston of the dust indicator laps over the peripheral red zone.

If the element is cleaned before the above, the air cleaner cannot display its normal performance and the cleaning effect decreases.
