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 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.
NOTICE
During the aftertreatment devices regeneration, aftertreatment devices regeneration display (1) lights up
on the machine monitor and the idle speed is set to rather high regardless of ON or OFF of AISS LOW
switch.
After the automatic regeneration is finished, aftertreatment devices regeneration display (1) goes out
and the idle speed is returned to the level corresponding to the AISS LOW switch.
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 when the KDPF soot
accumulation caution lamp (2) lights up.
• Accumulation amount of soot can be checked by soot ac-
cumulation level (3) on the “Aftertreatment Devices Regen-
eration” screen.
Operate the menu switch on the standard screen to dis-
play the “Aftertreatment Devices Regeneration” screen.
• Automatic regeneration against accumulation of soot starts
when the soot accumulation level increases “3” or above,
and stops a while after the soot accumulation level de-
creases to “0”.
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, 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.
For details of the procedure, see “PROCEDURE FOR MAN-
UAL STATIONARY REGENERATION (3-125)”.
Two types of monitor display require the manual stationary re-
generation, depending on the level of urgency.
When the gear shift lever is turned to NEUTRAL position (N)
and the parking brake switch is turned to the “PARKING” posi-
tion, the manual stationary regeneration may start automatical-
ly to protect the KDPF.
NOTICE
Do not stop engine when the aftertreatment devices regeneration is activated.
