EXPLANATION OF COMPONENTS OPERATION
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 (3-107)".
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 (3-64)".
Two types of machine monitor display require the manual stationary regeneration, depending on the level of ur-
gency.
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 system.
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 (3-109)", then keep en-
gine running 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 "PROCEDURE FOR MANUAL STA-
TIONARY 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.
