Having the soot particle filter system checked

The exhaust system contains a soot particle filter (DPF particle filter).
•
Check the operating status of the exhaust system on a daily basis by
checking the lamps (1) to (3) on the side console in the crane cab;

Operating manual .
– high exhaust gas temperature warning lamp (1),
– passive regeneration (2),
– active regeneration (3).
Under high loads (intensive crane operation for longer periods of time), the
passive regeneration system ensures permanent conversion of the soot
particles into gases that are then expelled. Under long periods of operation
at low loads (brief crane operation with long pauses) the warning lights indi-
cate that the system has switched over to active regeneration.
Active regeneration switches on automatically when the soot particle filter
is in danger of clogging. When this occurs, more diesel is injected into the
engine, which significantly increases the exhaust gas temperature and
burns the soot filter free of soot.
Active regeneration can be manually suppressed (3), and specific soot-
burning cycles are available;
documentation .
The soot particles are not completely burned away without residue, so that
the ash must be removed after a long period of operation;
