Marshalling the decoupled machine
CAUTION
Extreme caution is required for marshalling work with the operat-
ing brake system released, as only the marshalling vehicle now
can brake the machine.
The machine must be connected to the marshalling vehicle, be-
fore you actuate the release valve on the trailer brake valve.
The marshalling vehicle must have its brakes applied.
Two-line compressed air brake system
The operating brake system cannot be released using the re-
lease valve when the air pressure in the air tank falls below 3 bar
(e.g. through repeated actuation of the release valve or through
leakage in the brake system).
To release the operating brake
•
Fill the air tank.
•
Completely deaerate the brake system on the drain valve of
the air tank.
