METHOD FOR CHECKING AIR CLEANER
NOTICE
The electric air cleaner clogging sensor and dust indicator are used to indicate clogging on the air
cleaner. The electric air cleaner clogging sensor indicates the cleaning timing of the air cleaner element
and the dust indicator indicates the level of clogging.
Check the dust indicator before operating the machine so that cleaning of the air cleaner element is not
required during operation.
Clean the element when the yellow piston shown in dust indica-
tor (1) display of the air cleaner entered the red (7.5 kPa) posi-
tion.
After the cleaning, press the dust indicator button to reset it.
If the yellow piston enters the red (7.5 kPa) position soon after
the cleaning, the element must be replaced.
For the element replacement procedure, see "METHOD FOR
REPLACING AIR CLEANER ELEMENT (4-18)".
