Exhaust Filter Parked Cleaning

CAUTION: Servicing machine during exhaust
filter parked cleaning can result in serious
personal injury. Avoid exposure and skin contact
with hot gases and components.
During exhaust filter parked cleaning, the engine
may run at elevated idle and hot temperatures
for an extended period of time. Exhaust gases
and exhaust filter components may reach
temperatures hot enough to burn people and
ignite or melt common materials.
Avoid death or serious injury from machine
movement. Do not leave running machine
unattended during exhaust filter cleaning.
IMPORTANT: Avoid machine damage. Always
park machine in a safe location and check
for adequate fuel level before beginning
exhaust filter parked cleaning.
The exhaust filter parked cleaning process allows the
system to clean the exhaust filter when the filter restriction
is at HIGH or VERY HIGH soot levels. 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.
Operator can check the restriction level bar graph in
the monitor at any time. See Main Menu—Information
Menu—Monitoring. (Section 2-2.)
Before starting the parked cleaning process, the 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
An exhaust filter alarm indicator (1) on the monitor will
inform the operator when a parked cleaning needs to take
place.
•
If the alarm indicator is illuminated yellow, exhaust filter
restriction is at HIGH soot level and an exhaust filter
parked cleaning should be done soon.
•
If the alarm indicator is illuminated yellow and blinking,
exhaust filter restriction is at VERY HIGH soot level
and an exhaust filter parked cleaning should be done
immediately. Warning alarm indicator will also be
illuminated.
Before starting the parked cleaning process, make sure
the machine is in a safe state as listed previously. Once
these conditions are met, press and hold the exhaust
filter parked cleaning switch (3) on the right console for 3
seconds.
NOTE: If the safe state conditions are NOT met and the
exhaust filter parked cleaning switch is pressed and
