METHOD FOR CHANGING AIR CLEANER ELEMENT
NOTICE
• Do not clean and reuse the inner element. When replacing the outer element, replace the inner ele-
ment with a new one at the same time.
• If the outer element and cover are installed while the inner element is not installed properly, the out-
er element may be damaged.
• The sealing portion of the improper part lacks precision, and allows the entry of dust, which leads
to damage of the engine. Do not use such improper part.
Replace the outer element in the following procedure.
1.
Open the door at the rear left side of the machine and re-
move hooks (2) (4 places) to remove cover (3).
