11.4 Regeneration process for vehicles with a
diesel particle filter (DPF)
The DPF collects soot particles that are burned off by in-
creasing the emission temperature when the filter is
clogged (regeneration).
The regeneration process runs either automatically during
working mode or driving mode but can also be started
manually if required.
The higher the speed when driving, or the greater the load,
the less frequent the need for manual regeneration.

11.4.1Manual regeneration

WARNING
Risk of burns
During the regeneration process, exhaust gases up to a
temperature of 600°C may be omitted.
Do not start the regeneration process in combustible are-
as.
CAUTION
Risk of burns from hot exhaust gases
Keep people, animals and flammable objects away from
the regeneration area.
Note
Only interrupt the regeneration process in the case of an
emergency.
Manual regeneration is not possible at less than 50 hours.
The average duration of the burning procedure during
manual regeneration is approximately 20 minutes.

1. Manual regeneration can only be started when all 4
characteristics are green:
a The parking brake is activated
b The engine temperature has exceeded a particular
limit value
c The machine is in driving mode N (neutral)
d OK then lights up green and the manual burning pro-
cedure can be started

11.4.2Automatic regeneration

WARNING
Risk of burns
During the regeneration process, exhaust gases up to a
temperature of 600°C may be omitted.
Do not start the regeneration process in combustible are-
as.
Note
Work can continue during Automatic regeneration.
The automatic regeneration can be postponed in certain
situations.

Attachments

Note
Please read the attachment operating instructions before
fitting an attachment.
Attachments are optional and can be attached to the in-
tended attachment points on the vehicle.
DANGER
Danger due to changed vehicle centre of gravity and
changed driving behaviour.
When transporting liquids and/or bulk material, such as
e.g. loose chippings, swirling movements can occur which
cause the vehicle to rock up and down.
In the case of conversions, especially when converting
from winter to summer operation, and with changed load-
ing conditions, the driver must adjust to a changed driving
behaviour.
WARNING
Danger of crushing when mounting attachments
Do not reach between attachment points and the attach-
ment.
CAUTION
Risk of burns from hot hydraulic couplings
Wear protective gloves when disconnecting the hydraulic
couplings.
ATTENTION
Wear suitable protective clothing, safety gloves and gloves
when installing and removing attachments. This also ap-
plies during usage and application.
Please contact your responsible dealer before fitting at-
tachments that are not specifically intended for this vehi-
cle. Your dealer will check if installation and use of these
attachments is permitted on your vehicle. This is important
for the safety of the driver and the vehicle and also for any
warranty claims.
Attachments that endanger the safety or stability of the ve-
hicle may not be used.
