Operation—Operating the Machine
DB84312,000002F -19-21APR15-2/2
IMPORTANT: Avoid machine damage. Always
park machine in a safe location and check
for adequate fuel level before beginning
exhaust filter parked cleaning.
Parked cleaning is a process that allows the system to
clean the exhaust filter. It is most commonly initiated
after extended operation with exhaust filter auto cleaning
disabled or frequent engine shutdowns have occurred
while the auto cleaning process was active. (For more
detailed information, see Exhaust Filter Parked Cleaning
in this section.)
During the cleaning process, the engine speed will be
controlled automatically and the machine must remain
parked to complete the procedure. Complete cleaning
time takes less than 45 minutes, but will vary on several
criteria including fuel type, oil type, duty cycle, ambient
temperature, and the number of previously aborted
exhaust filter cleaning requests.
Parked cleaning can only be initiated if the filter restriction
is at HIGH or VERY HIGH soot levels. It is prompted by
an exhaust filter alarm indicator appearing on the monitor.
If exhaust filter alarm indicator is illuminated and yellow,
filter restriction is at a HIGH soot level and auto cleaning
needs to be enabled or a parked cleaning should be done
soon. If exhaust filter alarm indicator is blinking and yellow
along with the warning alarm indicator, filter restriction is
at a VERY HIGH soot level and a parked cleaning should
be done immediately.
Machine needs to be in a predetermined safe state. This
safe state includes three conditions:
•
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 exhaust filter parked cleaning switch is pressed
and held for 3 seconds, a parked cleaning progress
screen appears on monitor. Progress status is displayed
by a bar graph. The cleaning process will continue until
one of the following conditions exist:
•
there is no soot restriction in the exhaust filter
•
45 minutes has elapsed causing a timeout
•
operator cancels the parked cleaning procedure by
lowering the pilot shutoff lever or increasing engine
speed
•
parked cleaning 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
parked cleaning procedure, allow the engine and
exhaust filter time to return to normal operating
temperatures BEFORE stopping engine.
The exhaust filter cleaning indicator will be illuminated
on the monitor during the parked cleaning. When parked
cleaning procedure is complete, engine will automatically
return to slow idle and exhaust filter cleaning indicator will
turn off. Machine is ready to return to operation.
Avoid disabling the auto cleaning process unless
absolutely necessary. Repeated disabling of the auto
cleaning process or ignoring prompts to perform a parked
cleaning procedure, will cause engine power limitations
and can eventually lead to dealer required service
cleaning.
Ash Removal
The exhaust filter cleaning procedures listed previously,
clean the soot from the machine's exhaust filter. The
exhaust filter also traps ash deposits over time which
are not removed during an exhaust filter cleaning. When
the exhaust filter has run several thousand hours, these
ash deposits can restrict engine performance and must
be removed. For more information on ash removal, see
Service Exhaust Filter. (Section 3-3.)
