excessively or not run under a sufficient load. If
multiple successive regenerations are required,
it may indicate that the DPF will require service
soon, that an engine problem exists (e.g.,
incorrect engine fuel or oil) or that a DPF
pressure sensor is failing.
Important:
A stationary regeneration can
be initiated by the engine ECU or by you,
the user. You can monitor the DPF soot
percentage on the Engine-Off Screen or in
the Maintenance and Service Menu. If the
DPF Soot percentage is high, you may elect
to initiate a manual stationary regeneration
on the DPF Soot Percentage screen in the
Maintenance and Service Menu by selecting
Yes at the prompt.

Important:
During a stationary regeneration,
ensure that the machine is parked on a
hard, level surface in a well-ventilated area.
This process runs the machine at a higher
exhaust temperature for approximately 30
minutes to burn off collected particulate in
the DPF.
Note:
You cannot use the machine during a
stationary regeneration.
When the engine ECU determines that a
stationary regeneration is required, the module
displays the Allow Stationary Regen? prompt
screen. Select Y (yes) to start the stationary
regeneration process or N (no) to delay the
process.
Ensure that the machine has at least 1/4
tank of fuel. Disengage the blades, move the
motion-control levers to the N

position, and engage the parking brake.

Stationary Regen Required
If you do not perform a stationary
regeneration before the timer expires, the
engine enters a limp mode and the engine
ECU will require a recovery regeneration to
be performed. When the module indicates
that the engine has entered limp mode, the
engine speed and/or power is reduced and it
prevents clutch engagement.
