WARNING
• When using compressed air, there is a danger that dirt may scatter and cause personal injury.
Always wear protective eyeglasses, 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 re-
action when pulling out the outer element.
NOTICE
• Do not clean the air cleaner element until the air cleaner clogging caution lamp on the machine
monitor lights up. If the element is cleaned frequently before the air cleaner clogging caution lamp
on the machine monitor lights 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 any dirt enters the engine, it can damage the engine. Be sure to stop the engine before checking,
cleaning, or servicing the air cleaner. Do not check, clean, or service the air cleaner when strong
wind is blowing or in a dusty place.
When replacing the inner element, take extreme care.
• Replace the outer element if it is cleaned 6 times repeatedly or used throughout a year. Replace the
inner element as well at the same time.
METHOD FOR CHECKING AIR CLEANER
The air cleaner clogging caution lamp informs when the air cleaner element should be checked.
