Always use protective glasses, dust mask, and other protective equipment.
CHECKING
If air cleaner clogging caution pilot lamps (left, right) (1) on the
maintenance monitor flash, clean the air cleaner element.
NOTICE
Do not clean the air cleaner element before the air cleaner
clogging caution lamp flashes.
If the air cleaner element is cleaned frequently before the
air cleaner clogging caution lamp flashes, the proper per-
formance of the air cleaner is not provided and the clean-
ing efficiency is lowered.
In addition, dust sticking to the cleaner element falls on
the inner element side while cleaning the element.
REMARK
A dust indicator (with 5-stage display) is installed to the side of
the air cleaner. This displays the condition of the clogging of
the air cleaner.
This makes it possible to check the clean status of the element
and the replacement time.
