SYSTEM OPERATING LAMP
System operating lamp (1) indicates that the controller mount-
ed on the machine is turned ON.
Lamp (1) lights up in green when the controller is turned ON.
Usually, it goes out in 5 to 6 minutes after the starting switch is
turned to OFF position.
Before operating the battery disconnect switch, check that lamp
(1) is not lit.
NOTICE
If the battery disconnect switch is turned OFF while this
lamp is lit, the data in the controller may be lost.
REMARK
• Even if the starting switch is in OFF position, the controller may operate. The lamp lights up in this situation,
but it is not a failure.
• After the starting switch has been turned off, the system operating lamp may stay lit for a long time.
In such case, consult your Komatsu distributor.
• The system operating lamp may look slightly luminous in the dark after it is turned off. It is due to the minute
leakage of current and not an abnormal phenomenon.

CAUTION
• Exhaust gas temperature may increase higher than the previous models during aftertreatment devi-
ces regeneration and the high temperature may last after the completion of regeneration.
Avoid getting near the exhaust pipe outlet and around the aftertreatment devices to prevent being
burnt.
Also, keep combustible materials away from the exhaust pipe outlet and around the aftertreatment
devices to prevent a fire.
• When there are thatched houses, dry leaves or pieces of paper near the job site, set the system to
the regeneration disable to prevent fire hazards due to highly heated exhaust gas during aftertreat-
ment devices regeneration.
For the setting procedure, see “PROCEDURE FOR AFTERTREATMENT DEVICES REGENERATION
DISABLE SETTING (3-119)”.
KDPF is a device to capture soot in the exhaust gas to purify
the exhaust gas.
If soot is accumulated to a certain level in KDPF, a purification
process to burn the soot is performed automatically to keep the
filtering performance of KDPF high.
This purification process is called the “regeneration”.
If operations which lower the purification function of KDPF con-
tinues for long hours, the regeneration is performed to protect
the KDPF system, regardless of the quantity of the accumulat-
ed soot.
During the aftertreatment devices regeneration, the aftertreatment devices regeneration pilot lamp (1) stays lit
on the machine monitor.
