OPERATION
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.
Two types of monitor display require the manual stationary re-
generation, depending on the level of urgency.
When the directional lever is turned to NEUTRAL position (N)
and the parking brake switch is turned to the "ON" position, the
manual stationary regeneration may start automatically to pro-
tect the KDPF.
NOTICE
Do not stop engine when the aftertreatment devices regeneration is activated.
When stopping the engine, stop the aftertreatment devices regeneration first according to "PROCE-
DURE FOR AFTERTREATMENT DEVICES REGENERATION DISABLE SETTING", then keep engine run-
ning at low idle for approximately 5 minutes, and stop engine.
When the Action level "L03" lights up in red, and the KDPF soot accumulation caution lamp (2) lights up
in red, engine power deration is activated. To restore engine power, it is necessary to perform "PROCE-
DURE FOR MANUAL STATIONARY REGENERATION".
If soot accumulated in the KDPF exceed the defined level
without performing "PROCEDURE FOR MANUAL STA-
TIONARY REGENERATION", the Action level "L04" lights
up in red. Stop the machine immediately and ask your Ko-
matsu distributor.
