OPERATION
CLOCK
The clock indicates the current time.
AFTERTREATMENT DEVICES REGENERATION PILOT LAMP
• 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.
• If there is a thatched roof, dead leaves, paper, or other combustible matter near the machine, see
"HANDLE Komatsu Diesel Particulate Filter (KDPF) (3-130)".
Aftertreatment devices regeneration display indicates the re-
generation state of the aftertreatment devices.
(A): Lights up during regeneration of the aftertreatment devi-
ces. It goes out when the regeneration is completed.
(B): Lights up when KDPF is 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 re-
generation disable setting and perform manual stationary
regeneration.
For the procedures of cancellation of regeneration disable
setting, and setting of manual stationary regeneration, see
"HANDLE Komatsu Diesel Particulate Filter (KDPF)
(3-130)".
SECONDARY STEERING SYSTEM PILOT LAMP
The secondary steering pilot lamp lights up while the secon-
dary steering is in operation.
If the engine stops during travel or if the steering hydraulic cir-
cuit has a trouble and the machine is traveling at speed of
2 km/h or higher, the secondary steering operates automatically
and this lamp lights up.
Move the machine to a safe place, stop the engine, then per-
form the inspection and maintenance.
If the secondary steering has been operated for 60 seconds
continuously, the caution lamp lights up.
