Automatic regeneration
When indicator (2)
lights up
, this indicates that automatic regeneration is
due. If indicator (4) lights up in addition, automatic regeneration has started.
Automatic regeneration only starts under the following conditions:
▪ The regeneration block is switched off (see section
Blocking regeneration
).
▪ The coolant temperature is over 10 °C
▪ Moderate to high engine utilization
When the above conditions are no longer fulfilled, regeneration is stopped.
When the above conditions are fulfilled again, regeneration is resumed.
Regeneration is finished when indicators (2) and (4) have gone out.
NOTICE
If the automatic regeneration is interrupted several times or does
not start within 30 minutes or if the indicator (4) does not light
up, it is recommended that you start the manual regeneration in
order to prevent damage to the particle filter due to impermissi-
bly high soot concentration.
If the indicator (2)
flashes
, this indicates that the soot concentration in the
particle filter has already reached an increased value. The regeneration
should be started immediately. This can be done automatically or manually.

cannot be started. See also instructions in the documentation for
the complete machine.
