Only drive with the attachment properly mounted.
몇
CAUTION
Risk of damage
Make sure that the vehicle does not become stuck when
driving over obstacles.
Drive over obstacles up to 150 mm slowly and carefully at
an angle of 45°.
Obstacles above 150 mm may only be driven over using a
suitable ramp.
몇
CAUTION
Risk of damage due to flashing beacon
Pay attention to the protruding flashing beacon (2.20 m)
when driving into underground garages etc. If necessary,
remove it beforehand. Do not stand on the bonnet (fresh
water tank).
몇
CAUTION
Danger of accident
Switch off the PTO when driving on public roads for trans-
portation purposes (not when cleaning public roads).
Note
Releasing the accelerator pedal provides no noticeable
braking effect.
1. Fasten the seat belt.
2. Carefully press the accelerator pedal.
3. Steer the travel direction using the steering wheel.
4. The brake pedal must be pressed in order to brake.
7.3.4 Stopping
1. Take your foot from the accelerator pedal.
Note
Releasing the accelerator pedal provides no noticeable
braking effect in transport mode.
2. To stop or in an emergency, press the brake pedal.

7.3.6 Parking the vehicle
몇
WARNING
Risk of injury due to attachments
Fully lower any mounted attachments.

7.4
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.
7.4.1 Manual regeneration
몇
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.
몇
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.
