When Required; Check, Clean Or Replace Air Cleaner - Komatsu GALEO HM350-2 Operation & Maintenance Manual

MAINTENANCE
SERVICE PROCEDURE

WHEN REQUIRED

CHECK, CLEAN OR REPLACE AIR CLEANER

After the outer element has been cleaned 6 times, or if the air cleaner element has been used for one year, replace
the outer element, inner element, and O-ring. For details of the procedure for replacement, see "REPLACE
ELEMENT (PAGE 4-25)".
If the maintenance caution lamp lights up and the character display displays action code "E01" and "AIR FILTER"
during operation immediately after the outer element is cleaned, replace the element even if the outer element has
not been cleaned 6 times or the air cleaner element has not been used more than 1 year.
CHECKING
NOTICE
Do not replace the element before the dust indicator reaches 7.5 kPa. If it is cleaned frequently, the filtering effect of the air cleaner
will drop, and this will reduce the service life of the engine.
1. Check if the dust indicator (1) displays 7.5 kPa. If it is
displaying 7.5 kPa, clean the outer element.
REMARK
There is maintenance caution lamp (2) on the machine monitor. If
the maintenance caution lamp lights up and the character display
(3) displays "E01" and "AIR FILTER" during operation, the air
cleaner is clogged. Clean the air cleaner element in this case, too.
