Coupling and uncoupling the machine
7.2.1
Manoeuvring the uncoupled machine
DANGER
You must be particularly careful when manoeuvring the machine
with the service brake system released, since only the manoeu-
vring vehicle is now braking the machine.
The machine must be connected to the manoeuvring vehicle
before you actuate the release valve on the trailer brake valve.
The manoeuvring vehicle must be braked.
The service brake system cannot be released using the release valve
if the air pressure in the air reservoir drops below 3 bar (e.g. if the
release valve has been actuated multiple times or if there are leaks in
the brake system).
To release the service brake
•
Fill the air reservoir.
•
Remove all air from the braking system at the drain valve on the
air reservoir.
1. Connect the machine to the manoeuvring vehicle.
2. Brake the manoeuvring vehicle.
3. Remove the wheel chocks and release the parking brake.
4.
Pneumatic braking system
only:
4.1 Press in the actuator button on the release valve as far as it
will go (see page 47).
7.
The service brake system is released and the machine can
be manoeuvred.
4.2 Once the manoeuvring procedure is finished, pull out the
actuator button on the release valve as far as it will go.
7.
The pressure from the air reservoir brakes the machine again.
5. Actuate the brakes on the manoeuvring vehicle again once you
have finished manoeuvring the machine.
6. Firmly apply the parking brake again and secure the machine
against rolling with wheel chocks.
7. Uncouple the machine and manoeuvring vehicle.
