MAINTENANCE

WHEN REQUIRED

CHECK, CLEAN AND REPLACE AIR CLEANER ELEMENT

When using compressed air, there is danger of dirt flying and causing personal injury.
Always wear protective glasses, dust mask, or other protective equipment.
When removing the outer element from the air cleaner body, it is dangerous to pull it out by force.
When working at high places or where the foothold is poor, be careful not to fall because of the reac-
tion when pulling out the outer element.
Checking
If air cleaner clogging monitor (1) of the monitor panel flashes,
clean the air cleaner element.
Replacing
Replacing element, O-ring
If one year has passed since installing the element or if air
cleaner clogging monitor (1) on the monitor panel flashes
immediately after the element is cleaned, replace the outer
element, inner element, and O-ring.
Replacing evacuator valve
Replace it if it is damaged or the rubber is markedly
deformed.
NOTICE
Do not clean the air cleaner element until the air cleaner clogging monitor on the monitor panel flashes. If
the element is cleaned frequently before the clogging monitor flashes, the air cleaner will not be able to
display its performance fully, and the cleaning efficiency will also go down.
In addition, during the cleaning operation, more dirt stuck to the element will fall inside the inner element.
Cleaning or replacing outer element
1. Open the rear door at the left side of the machine, remove 4
hooks (2), then remove cover (3).
NOTICE

it in direct sunlight.
2. Hold the outer element, rock it lightly up and down and to the left and right, and rotate the element to the left
and right to pull it out.
NOTICE
Never remove the inner element. It will allow dirt to
enter and cause failure of the engine.
Do not use a screwdriver or other tool.
3. Hold the outer element, rock it lightly up and down and to
the left and right, and rotate the element to the left and right
to pull it out.
