Shunting the uncoupled machine
Dual circuit air brake system
CAUTION
You must be particularly careful when shunting the machine with
the service brake system released, since only the manoeuvring
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 brakes on the manoeuvring vehicle must be on.
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).
Release the service brake as follows:
Fill the air reservoir.
Completely deaerate the brake system using the drain valve
on the air reservoir.
1. Connect the machine to the manoeuvring vehicle.
2. Actuate the brakes on the manoeuvring vehicle.
3. Remove wheel chocks.
4. Pull out the release valve until it reaches the stop position.
This releases the service brake system so that the machine can
be shunted.
5. Once shunting is complete, push in the release valve until it
reaches the stop position.
The pressure from the air reservoir brakes the machine again.
6. Actuate the brakes on the manoeuvring vehicle.
7. Secure the machine against rolling away with wheel chocks.
8. Uncouple the machine from the manoeuvring vehicle.
Hydraulic brake system
DANGER
You must be particularly careful when shunting the machine,
since only the manoeuvring vehicle is now braking the machine.
The machine must be connected to the manoeuvring vehicle
before you release the parking brake.
The brakes on the manoeuvring vehicle must be on.
1. Connect the machine to the manoeuvring vehicle.
2. Actuate the brakes on the manoeuvring vehicle.
3. Remove wheel chocks.
4. Actuate the brakes on the manoeuvring vehicle again once you
have finished shunting the machine.
5. Secure the machine against rolling away with wheel chocks.
6. Uncouple the machine from the manoeuvring vehicle.
