NOTICE
Damage to the diesel particulate filter!
If the soot load in the diesel particulate filter reaches a critical value, this
can lead to damage to the diesel particulate filter or the engine. For
safety reasons, the engine power is reduced.
► If the engine power is reduced, carry out a manual regeneration im-
mediately.
► Wait until manual regeneration is finished.
NOTICE
Damage to the diesel particulate filter
When the engine is running at idling speed and the electrical consumers
on the vehicle are switched on, the current regeneration can be interrup-
ted.
► During regeneration at idling speed, switch off all electrical loads on
the vehicle, e.g. rotating beacon, lighting, radio, etc.
Maintenance and repair on the diesel particulate filter may only be per-
formed by an authorized service center. The diesel particulate filter is a
wear part and has to be checked/cleaned or replaced by an authorized
service center every 3000 operating hours.

The combustion of diesel produces soot. The soot is collected in the
diesel particulate filter and burnt at regular intervals. During combustion,
the so-called regeneration, exhaust gas temperatures of up to approx.
600 °C occur at the silencer outlet.
The soot load in the diesel particulate filter is the level of contamination of
the diesel particulate filter and is called soot load. The soot load is influ-
enced, among other things, by the load on the engine.
• High engine loads mean less deposits.
• Low engine loads mean higher deposits.
