7.9 Regenerating the diesel particulate filter
The engine has an automatic regeneration process for cleaning the diesel
particulate filter (DPF).
The diesel particulate filter filters soot particles out of the exhaust gas. Dur-
ing regular regeneration the accumulated soot particles are burnt off at high
temperatures.
The regeneration process starts automatically and takes approx. 15 minutes.
In special situations, it can be suppressed using a pushbutton on the instru-
ment box.
Safety notes
DANGER
Danger of fire from hot exhaust gas system.
The exhaust gas system and, in particular, the diesel particulate
filter can become very hot. Combustible materials can ignite on
the exhaust gas system, even when the engine has already
been switched off.
▪ Keep combustible materials away from the exhaust gas sys-
tem.
▪ Do not operate and place the engine in the direct vicinity of
combustible materials.
CAUTION
Danger of damaging the diesel particulate filter.
If the regeneration of the diesel particulate filter is suppressed
over a longer period, a large amount of particles collects in the
filter. This can damage or destroy the diesel particulate filter.
▪ Only suppress regeneration when needed, and reactivate it
again as soon as possible.
