NOTICE
If the battery disconnect switch is turned OFF while the system operating lamp is lit, the data in the con-
troller may be lost.
If the data are lost, when you try to start the engine next time, “L04” is displayed on the machine moni-
tor and the engine may not start.
If the engine cannot be started, ask your Komatsu distributor for inspection and repair.
REMARK
• Even if the starting switch is in OFF position, the controller may operate. The system operating lamp lights
up at this time, but it is not a failure.
• After the starting switch is turned to OFF position, if the system operating lamp stays lit for a long time, con-
sult your Komatsu distributor.
• The system operating lamp may look slightly luminous in the dark when it is not lit. It is due to the minute
leakage of current and this is not an abnormal phenomenon.

CAUTION
• Exhaust gas temperature may increase during the aftertreatment devices 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.
Keep combustible materials away from the exhaust pipe outlet and around the aftertreatment devi-
ces 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 the after-
treatment devices regeneration.
• Do not leave the operator's seat during the regeneration of the aftertreatment devices.
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 the filter, a purifica-
tion process to burn the soot is performed automatically to
keep the filtering performance of KDPF high.
This purification process is called “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 regeneration of KDPF, aftertreatment devices regen-
eration pilot lamp (1) stays lit on the machine monitor.
REMARK
Even if aftertreatment devices regeneration pilot lamp (1) lights
up, the machine does not need to be stopped and the work can
be continued, unless the caution lamp is displayed at the cen-
ter of the machine monitor.
The KDPF regeneration is performed automatically. However,
the accumulated soot may not be burnt sufficiently and the fil-
tering function may not be improved under certain operating
conditions.
In that case, the KDPF soot accumulation caution lamp (2) lights up. If this lamp lights up, stop the machine in a
safe place and perform the manual stationary regeneration.
