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.
NOTICE
• 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.
When replacing the inner element, take extreme care.
• Replace the outer element if it is cleaned 5 times repeatedly or used throughout a year. Replace the
inner element as well at the same time.
METHOD FOR CHECKING AIR CLEANER
1.
Pull engine rear cover (1) toward you to open it.
Open engine rear cover (1) fully and it is secured by rod
(2).
NOTICE
Do not clean the outer element before the red piston is
projected into the transparent part of dust indicator (3).
If the outer element is cleaned frequently before the red
piston protrudes, the air cleaner cannot display its normal
performance and the cleaning effect decreases.
2.
Check if the red piston is projected into the transparent
part of dust indicator (3).
If the red piston is projected, clean the air cleaner outer el-
ement.
