Removing the
supply lines
• Proceed as follows:
– First disconnect the hose of the supply line
from the coupling head (1) – red. Now the
trailer is braked.
– Then disconnect the hose of the brake pipe
from the coupling head (4) – yellow.
• Remove the plug (5) of the trailer’s electrical
system from the socket.
• If necessary, remove the plugs (2) and (3) from
the sockets (ABS and special equipment).
Uncoupling
the trailer
• Secure the trailer with the (trailer) parking brake
and chocks as prescribed to prevent it from
rolling away.
• Open the towbar coupling.
Push the lever (1) up until it latches into place.
• Drive the truck crane carefully away from the
trailer.
G
Risk of accidents due to trailer rolling in!
Always first remove the hose from the supply line so that the trailer is braked.
This prevents the trailer moving when you remove the brake hose.
G
Risk of injury when the automatic closing device is triggered!
Never put your hand into the coupling jaw when the towbar coupling is open.
This prevents the coupling closing automatically, and the cotter pin causing
serious injury to your hand.
