5.5.7 Check and clean clogging of air filter element
[Every 250 hours]
When an element that is clogged or has holes or cracks is used, dust or foreign material will get in the
engine. This causes accelerated wear in each sliding part of the engine. Be sure to make daily check
and cleaning so that the life of the engine will not be shortened
.
Remove both external shell“2” and clean them.
Replace both internal shell“1”once in the proportion
of replacing external ones four times. The internal
ones can never be reused even after they are cleaned.
When it is found that they cannot be repaired even
after being cleaned, replace the elements. (See 5.5.16)
When installing a new element, pay attention to the
followings.
Put the element fully into the case.
Make sure there is no foreign matter at the contact
face of the case.
