Maintenance 5
Engine
If this time period is exceeded, the orange indi-
cator light (5) flashes and the buzzer sounds,
or the build-up indicator (7) continues to flash
and the particulate filter alarm (6) lights up
on the indicator unit. In addition, the buzzer
sounds continuously and the truck only moves
at crawling speed. In this case, switch off the
truck engine as quickly as possible and per-
form filter regeneration. Regeneration can
however also be triggered before the maxi-
mum build-up time.
DANGER
Do not handle fuel while regeneration is in progress.
In particular do not fill up the truck with fuel during
regeneration.
WARNING
During regeneration, high tempera-
tures occur in the particulate filter,
the exhaust system and in their vi-
cinity. For reasons of fire safety do
not allow the regeneration exhaust

Perform regeneration only in the
open air with the engine at operating
temperature and away from combus-
tible materials. Anything touching
the exhaust system may catch fire.
CAUTION

generation interrupted for safety reasons, the stop
switch (3) must be unlocked and pressed. The re-
generation process will immediately be terminated,

been interrupted, the particulate filter will not have
been regenerated!
Regeneration should only be interrupted in an
emergency as this may lead to system damage.
