1. Open the cover of the hose couplings on the tractor.
2. Remove the hose coupling of the brake line (yellow) from the
empty coupling.
3. Check the sealing rings on the hose coupling for damage and
cleanliness.
4. Clean soiled sealing rings and replace damaged sealing rings.
5. Fix the hose coupling of the brake line (yellow) in the yellow
coupling on the tractor in accordance with the regulations.
6. Remove the hose coupling of the supply line (red) from the emp-
ty coupling.
7. Check the sealing rings on the hose coupling for damage and
cleanliness.
8. Clean soiled sealing rings and replace damaged sealing rings.
9. Fix the hose coupling of the supply line (red ) in the red coupling

On coupling the supply line (red), the supply pressure coming
from the tractor automatically pushes out the button for the re-
lease valve on the trailer brake valve.

5.3.2
Decoupling the brake and supply lines
WARNING
Risk of contusions, cuts, dragging, catching or knocks from
unintentionally rolling machine with the operating brake re-
leased!
Always decouple the hose coupling of the supply line (red) first fol-
lowed by the hose coupling of the brake line (yellow).
The operating brake of the machine only moves into the brake posi-
tion when the red hose coupling has been decoupled.
Always keep to this order, as otherwise the operating brake system
will trip and may set the unbraked machine moving.
When decoupling or disconnecting the machine, the supply line to the
trailer brake valve de-aerates. The trailer brake valve automatically
switches over and actuates the operating brake system depending on
the automatic, load-dependent brake power controller.
1. Secure the machine against unintentional rolling. For this, use
the parking brake and/or wheel chocks.
2. Slacken the hose coupling of the supply line (red).
3. Slacken the hose coupling of the brake line (yellow).
4. Fix the coupling heads in the empty couplings.
5. Close the cover of the hose couplings on the tractor.
