Key off regeneration allows for regeneration when
t
he engine
start switch key has been removed. To
begin a key off regeneration, the soot level must be
between 15% and 100% on the soot level monitor
and/or a regeneration is in progress. The following
steps outline the procedure of a key off regeneration:
1. T
urn the engine start switch to the OFF position.
2. The engine will continue to run for 15 se
conds.
During this 15 second interval, if a regeneration
is desired, press and hold the force regeneration
switch for 2 seconds.
Note: I
f a regeneration is not desired, the machine
will initiate the delaye
d engine shutdown.
3. The key off regeneration will activate and
the key
off regeneration will last for up to 15 minutes.
Note: If at anytime the regeneration needs to be
stopped,
press and hold the disable regeneration
switch.
4. Onc
e the key off regeneration is complete, the
machine will initiate the delayed engine
shut
down.
5. The delayed engine
shutdown will
last for 5
minutes.
6. After the delayed engine shutdown has been
completed, the engine will shut down.
