REMARK
If heavy-duty operation is performed for more than 30 minutes
with the fuel control dial between Low idle (MIN) position and
High idle (MAX) position, soot is accumulated much and action
level “L03” may be displayed. However, this does not indicate
abnormality.
After performing manual stationary regeneration, turn the fuel
control dial to a point above the midpoint between Low idle
(MIN) position and High idle (MAX) position to continue the op-
eration.
When the degree of urgency is low
• If KDPF soot accumulation caution lamp (2) lights up in
yellow (action level (3): “L01”), screen (A) is displayed first.
• The action level goes out 2 seconds later, and the screen
changes back to standard screen (B).
• If the lock lever is set to LOCK position or all the work
equipment control levers are set in NEUTRAL, the screen
changes to “Aftertreatment Devices Regeneration” screen
(C) after 3 seconds only the first time. If the manual sta-
tionary regeneration is not performed, the screen returns
to standard screen (B) after 30 seconds.
Then, if the accumulated soot does not decrease, “After-
treatment Devices Regeneration” (C) is displayed for 30
seconds every 2 hours.
• If the KDPF soot accumulation caution lamp (2) lights up in
yellow, stop the machine in a safe place after finishing the
work and perform the manual stationary regeneration.
