METHOD FOR CHECKING, CLEANING AND REPLACING AIR CLEANER
•
When using compressed air, there is a danger that dirt may scatter and cause personal injury.
Always wear the 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 element before the yellow piston shown in dust indicator (2) display enters the red
(7.5 kPa {0.08 kg/cm
If the element is cleaned frequently before the yellow piston of the dust indicator enters the red
(7.5 kPa {0.08 kg/cm
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 in strong winds,
or in a dusty place.
In addition, during the cleaning operation, more dirt stuck to the element will fall inside the inner
element.
•
Replace the outer element if it is cleaned 6 times or used throughout a year. Replace the inner ele-
ment as well at the same time.
