Indicator behavior
A specific amount of PM has accumulated in
the DPF muffler.
Continue to work the tractor to raise the DPF
temperature.
Continue the work and increase the engine
rpm until the indicator turns "OFF."
The parked regeneration can also be started.
(See Operating the engine to regenerate the
DPF for parked regeneration on page 52)
The regeneration cycle begins and continues
until cycle is complete then the indicator will
turn "OFF."
Start the regeneration, according to the pre-
ceding PM-warning level 1.
Now the parked-regeneration indicator starts
flashing, and the parked regeneration can al-
so be started.
If the conditions of regeneration are not met,
perform the procedure for parked regenera-
tion cycle.
(See Operating the engine to regenerate the
DPF for parked regeneration on page 52)
The regeneration cycle begins and continues
until cycle is complete then the indicator will
turn "OFF."
Immediately discontinue working the tractor
and begin the procedure for parked regener-
ation cycle.
(See Operating the engine to regenerate the
DPF for parked regeneration on page 52)
At PM-warning level 3, the auto-regeneration
mode does not function.
If the tractor is operated further, the regener-
ation cycle will be disabled.
Immediately move the tractor to a safe place,
park it there, and turn the engine "OFF."
