MAINTENANCE PROCEDURE

WHEN REQUIRED

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.
METHOD OF CHECKING
NOTICE
Do not clean the air cleaner element until the air cleaner clogging caution lamp lights up and the action
level "L01" is displayed.
If the element is cleaned frequently before the air cleaner clogging caution lamp lights up and the action
level "L01" is displayed, the air cleaner will not be able to display its performance fully, and the cleaning
efficiency will go down.
In addition, during the cleaning operation, more dirt stuck to the element will fall inside the inner ele-
ment side.
If the air cleaner clogging caution lamp lights up and the action
level "L01" is displayed, clean the air cleaner element.
METHOD FOR CLEANING AND REPLACING OUTER ELEMENT
1.
Open the engine side cover on the left side of the machine.
2.
Remove the clips (1) (3 pieces) and remove the cover (2).
