Passive regeneration is made automatically
and is not visible to the operator.
It is recommended to operate the loader with
varying load.
Automatic
Assisted passive regeneration
The ECU will assist the continuous, passive
regeneration by increasing the exhaust
temperature.
Allow the engine to reach its normal
operating temperature during normal use to
facilitate the automatic, passive
regeneration.
80 - 90 %
None. Continue to operate the loader with
varying load. Avoid idling of the engine.
Symbol warning of high exhaust
temperature may appear, avoid driving near
combustible materials.
If you want to abort or postpone the
regeneration process press button on the
display.
Automatic, with possibility to inhibit
Active regeneration
The engine ECU will actively increase the
exhaust temperature to regenerate the DPF.
With this soot load it is advisable to continue
to use the loader with load. It is not
recommended to stop the loader or to leave
it idling during regeneration.
90 - 100 %
A request for parked regeneration is
shown on the display. When request
appears:
Operate the loader until the engine reaches
its normal operating temperature. Avoid
idling.

minutes.
Engine power is limited if the soot level is
above 100 %.
Must be started manually
Automatic process after starting.
Active, parked regeneration
Once the conditions for the parked
regeneration are met, the engine ECU will
increase the engine RPM and regenerate
the DPF by actively increasing the exhaust
temperature.

Engine power is limited.
Regeneration at authorized service is
necessary.
If the active parked regeneration is not
made, and the soot load reaches above
110 % level, it is no longer possible to
regenerate the DPF without visit to
authorized Avant service.
