Operation—Operating the Machine
KR46761,0001389 -19-21SEP16-2/2
Manual regeneration is a process that allows the operator
to clean the aftertreatment device. Regeneration is
most commonly initiated after extended operation
with aftertreatment device regeneration inhibited or
frequent engine shutdowns have occurred while the
auto-regeneration process was active. (For more detailed
information, see Aftertreatment Device Regeneration in
this section.)
During aftertreatment device regeneration, the engine
speed will be controlled automatically and the machine
must remain parked to complete the procedure. Complete
regeneration time will vary on several criteria including
fuel type, oil type, duty cycle, ambient temperature, and
the number of previously aborted aftertreatment device
regeneration requests.
Manual regeneration is initiated by an aftertreatment
device regeneration request appearing on the monitor. If
aftertreatment device regeneration request is yellow and
blinking, manual regeneration should be performed soon.
Machine needs to be in a predetermined safe state. This
safe state includes six conditions:
•
Keep bystanders clear of machine.
•
Fuel level alarm is not illuminated.
•
Diesel exhaust uid (DEF) level alarm is not illuminated.
•
Machine is parked in a safe place with the front
attachment lowered to the ground.
•
Pilot shutoff lever is in locked (UP) position.
•
Engine speed dial is set to slow idle.
Once the aftertreatment device regeneration switch
is pressed and held for 3 seconds, an aftertreatment
device regeneration progress screen appears on monitor.
Progress status is displayed by a bar graph. The manual
regeneration will continue until one of the following
conditions exist:
•
There is no soot restriction in the aftertreatment device.
•
Operator cancels manual regeneration procedure by
lowering the pilot shutoff lever or increasing engine
speed.
•
Manual regeneration is aborted due to a system
malfunction.
•
Engine runs out of fuel.
•
Engine is shut off by operator (not recommended).
IMPORTANT: Avoid engine damage. If machine will
NOT be returning to operation immediately
after a manual regeneration procedure, allow
the engine and aftertreatment device time
to return to normal operating temperatures
BEFORE stopping engine.
The aftertreatment device regeneration request will be
illuminated on the monitor during manual regeneration.
When manual regeneration procedure is complete,
monitor will display a message that regeneration has
completed, engine will automatically return to slow idle,
and aftertreatment regeneration device indicator will turn
off. Machine is ready to return to operation.
Avoid inhibiting the aftertreatment device regeneration
unless absolutely necessary. Repeated inhibiting of the
aftertreatment device regeneration or ignoring prompts to
perform a manual regeneration, will cause engine power
limitations and can eventually lead to dealer required
service cleaning.
