Komatsu WA380-8, Operation & Maintenance Manual

Page: 197 / 432

When the machine is backed up and rear view monitor (1) is
set in operation, a monitor screen enables the operator to
check the rear for safety.
REMARK
• The screen may be hard to see in the dark place at night,
but it is not a trouble.
The luminance of the rear view monitor can be adjusted
with rear view monitor brightness adjustment switch (2).
For the adjustment method, see “BRIGHTNESS ADJUST-
MENT SWITCH OF REAR VIEW MONITOR (3-98)”.
• Reference line (3) is used for checking the side and rear of
the machine roughly.
For the setting of the rear view monitor, see “REAR VIEW
MONITOR SETTING (3-77)”, and for the setting of refer-
ence line, see “METHOD FOR ADJUSTING REAR VIEW
CAMERA ANGLE (3-178)”.
• Reference line (3) dose not synchronize with steering an-
gle. Reference line (3) does not indicate the actual moving
direction or travel path.

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.
For the setting, see “PROCEDURE FOR AFTERTREATMENT DEVICES REGENERATION DISABLE
SETTING (3-139)”.
• Do not leave the operator's seat during the aftertreatment devices regeneration.
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.
During the KDPF regeneration, aftertreatment devices regeneration pilot lamp (1) lights up on the monitor.
