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 in high places
or where the foothold is poor, be careful not to fall because of the reaction when pulling out the outer element.
NOTICE
Do not clean the air cleaner element until the air cleaner clogging monitor on the monitor panel light up. If the element is
cleaned frequently before the air cleaner clogging monitor light up, 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.
If inspection, cleaning, or maintenance is carried out with the engine running, dirt will enter the engine and cause damage to
the engine. Always stop the engine before carrying out these operations.
Checking
If air cleaner clogging monitor (1) of the monitor panel flashes,
clean the air cleaner element.
Replacing
Replace element, O-ring
If the element has been used for 1 year, or air cleaner clogging
monitor (1) on the monitor panel lights up after the element has
been cleaned, replace outer element (5), inner element (6), and
O-ring (8).
Replacing evacuator valve
Replace evacuator valve (4) if it is damaged or if the rubber is
markedly deformed.
