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. Wear
the protective equipment such as protective eyeglasses and dust mask.
• When working on a high place or in the place where the foothold is poor, be careful not to fall be-
cause of the reaction when pulling out the outer element.
NOTICE
If the air cleaner is not cleaned or maintained sufficiently, the mass air flow sensor which is installed to
the air cleaner does not function correctly, and it may cause a decrease in the engine performance.

chine monitor is lit.

air cleaner element.
