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.
Also, keep combustible materials away from the exhaust pipe outlet and around the aftertreatment
devices 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 aftertreatment devices regeneration.
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.
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.
REMARK
• Even if the aftertreatment devices regeneration display (1)
lights up, the machine does not need to be stopped and
the work can be continued, unless the KDPF soot accumu-
lation caution lamp (2) is lit.
• Accumulation amount of soot can be checked by the soot
accumulation level (3) on “Aftertreatment Devices Regen-
eration” screen.
Operate the menu switch on the standard screen to dis-
play “Aftertreatment Devices Regeneration” screen.
• Automatic regeneration against accumulation of soot starts
when the soot accumulation level increases to “3” or
above, and stops a while after the soot accumulation level
decreases to “0”.
