Operation—Operating the Machine
KR46761,000138A -19-19OCT16-2/2
Aftertreatment device regeneration indicator (4) will
illuminate on the monitor and a manual aftertreatment
device regeneration progress screen (5) appears.
Progress status is displayed on the bar graph (6).
During aftertreatment regeneration, the engine speed will
be controlled automatically and the machine must remain
parked to complete the procedure. Complete regeneration
will vary on several criteria including fuel type, oil type,
duty cycle, ambient temperature, and the number of
previously aborted aftertreatment device regeneration
requests. Exhaust combustion may temporarily emit white
smoke during the regeneration process.
The regeneration process will continue until one of the
following conditions exist:
•
Pilot shutoff lever is moved.
•
Engine speed dial is moved.
•
Aftertreatment device regeneration is aborted due to a
system malfunction.
•
Engine runs out of fuel.
•
Engine is shut off by operator (not recommended).
If any of these conditions happen during the
aftertreatment device regeneration, the process will
be cancelled and a message will be displayed on
the monitor informing the operator. The condition will
need to be amended and the aftertreatment device
regeneration must be started over. For a system
malfunction, see an authorized Hitachi dealer.
IMPORTANT: Avoid engine damage. If machine will
NOT be returning to operation immediately
after a manual regeneration, allow the engine
and aftertreatment device regeneration time
to return to normal operating temperatures
BEFORE stopping engine.
NOTE: If machine needs to be operated during the
aftertreatment device regeneration, press the
aftertreatment device regeneration switch again.
The process will be cancelled and a message
will be displayed on the monitor informing the
operator. Machine operation can resume, but
an aftertreatment device regeneration must be
performed as soon as possible.
When there is no restriction in the aftertreatment
device, the aftertreatment device regeneration is
complete. Engine will automatically return to slow idle
and aftertreatment device regeneration request will
turn off. A message will appear on the monitor stating,
“Regeneration Has Completed,” and the machine is ready
to return to operation.
