Structure and function
1. Open the tractor coupling head caps.
2. Remove brake line coupling head (yellow) from the empty cou-
pling.
3. Check coupling head seals for damage and cleanness.
4. Clean dirty seals, replace damaged seals.
5. Fasten the brake line coupling head (yellow) as directed in the
tractor coupling with the yellow marking.
6. Remove the supply line coupling head (red) from the empty
coupling.
7. Check coupling head seals for damage and cleanness.
8. Clean dirty seals, replace damaged seals.
9. Fasten the supply line coupling head (red) in the tractor coupling
with the red marking, as instructed.
→
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.
10. Remove wheel chocks.
5.1.2
Uncoupling 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 uncouple 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 uncoupled.
Always keep to this order, as otherwise the operating brake system
will trip and may set the unbraked machine moving.
When the machine is uncoupled or pulled away from the trailer, air is
vented from the trailer brake valve supply line. The trailer brake valve
is automatically switched and operates the service braking system
independently of the automatic, load-dependent braking force regula-
tor.
1. Secure the machine against unintentionally rolling away.
Use chocks.
2. Release supply line coupling head (red).
3. Release brake line coupling head (yellow).
4. Fasten coupling heads in the empty coupling points.
5. Close tractor coupling head caps.
