7.5.5 Having the soot particle filter system checked
Checking daily 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 instrume
nt panel in the driver's cab;
à Operating manual.
– High exhaust gas temperature warning lamp (1),
– p
assive regeneration (2),
– active regeneration (3),
H
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 (city traffic) the warning lights indicate 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;
à Operating manual; à Engine manufacturer’s
documentation
.
The soot particles are not completely burned away without residue, so that
the ash must be rem
oved after a long period of operation;
à P. 7 - 41.
S
Risk of damage to the pump unit!
Oil from the compressed air system can damage the pump unit.
Therefore, a filter cartridge must be installed in the compressed air d
rier
that removes both water and oil.
Manitowoc Crane Care recommends the
suitable filter cartridge with the GROVE part number 04156032.
