REMARK
Even if the 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 center 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, 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 (3-117)”.
If hydraulic fan reverse operation is performed while the after-
treatment devices regeneration pilot lamp or the KDPF soot ac-
cumulation caution lamp is lit, the accumulated soot may not be
burnt sufficiently and the filtering function may not be improved.
Wait until the aftertreatment devices regeneration pilot lamp or
the KDPF soot accumulation caution lamp goes out, and then
perform hydraulic fan reverse operation.
For the operation to reverse the hydraulic fan rotation, see “MACHINE SETTINGS (3-73)”.
2 types of machine monitor require the manual stationary regeneration, depending on the level of urgency.
If the parking brake lever and work equipment lock lever are set to LOCK position, the manual stationary regen-
eration may start automatically to protect the KDPF.
NOTICE
Do not stop engine when the aftertreatment devices regen-
eration is activated.
When stopping the engine, stop the aftertreatment devices
regeneration first according to “PROCEDURE FOR AFTER-
TREATMENT DEVICES REGENERATION DISABLE SET-
TING (3-119)”, then keep engine running at low idle for ap-
proximately 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 “PROCEDURE FOR MANUAL STA-
TIONARY REGENERATION (3-117)”.
If soot accumulated in the KDPF exceed the defined level without performing “PROCEDURE FOR MANUAL
STATIONARY REGENERATION (3-117)”, the Action level “L04” lights up in red. Stop the machine immediately
and ask your Komatsu distributor.
