CAUTION
• Exhaust gas temperature may increase higher than the previous models during the aftertreatment
devices regeneration.
Stay away from the exhaust pipe outlet to prevent yourself from getting burnt.
Also, keep combustible materials away from the exhaust pipe outlet 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 details of the setting method, see “HANDLE Komatsu Diesel Particulate Filter (KDPF) (3-121)”.
Aftertreatment devices regeneration display indicates the re-
generation state of the exhaust gas aftertreatment devices.
(A): Lights up during regeneration of the exhaust gas aftertreat-
ment devices. It goes out when the regeneration is complet-
ed.
(B): Lights up when the exhaust gas aftertreatment devices are
set to “Regeneration Disable”.
REMARK
• The lighting cycle becomes shorter when the ambient tem-
perature is lower or working load is smaller.
• Even if the aftertreatment devices regeneration is disabled,
when the manual stationary regeneration is necessary,
KDPF soot accumulation caution lamp lights up.
If KDPF soot accumulation caution lamp lights up, cancel
the regeneration disable setting and perform manual sta-
tionary regeneration.
For the procedures of cancellation of regeneration disable
setting, and setting of manual stationary regeneration, see
“HANDLE Komatsu Diesel Particulate Filter (KDPF)
(3-121)”.
