Maintenance 5
Engine
In the event of an error during the regeneration
procedure, the orange indicator light (5) and
the red indicator light (4) flash alternately, or
the particulate filter alarm (6) lights up and text
field (8) of the indicator unit displays an error
code.
Start regeneration again. If the fault still per-
sists, switch off the truck. Please contact your
authorised dealer.
NOTE
To switch off the buzzer, press the reset switch
(9). If the buzzer continues to sound, please
contact your authorised dealer. Whilst driving,
the glow plugs of the regeneration system
are cleaned every 1.75 hours by intermediate
heating.
Regenerating the particulate filter
(exchange filter system)
The particulate filter must be regenerated after
a maximum of 8.5 hours’ engine operation.
After 8.0 hours, the orange indicator light (1)
illuminates in the switch panel at the top-right
as an optical display, and a buzzer sounds.
The clogged up filter must be changed for a
regenerated filter within the next 30 minutes.
If the exhaust gas back pressure exceeds the
admissible level before the 8 hours are up, this
is also shown by the orange indicator light and
the buzzer. In this case, the filter must also be
changed within 30 minutes.
CAUTION
In the event of a power failure (e.g. disconnected
battery), the loading time and filter capacity can be
exceeded.
Therefore, in the interest of safety, regenerate the
particulate filter immediately.
NOTE
Select an appropriate location to assemble the
regeneration system. Do not introduce rege-
neration exhaust gases into suction systems
or work areas.
