5. Remove the hose coupling of the supply line (red) from the emp-
ty coupling.
6. Check the sealing rings on the hose coupling for damage and
cleanliness.
7. Clean the dirty sealing rings and replace any damaged sealing
rings.
8. Fasten the hose coupling of the supply line (red) in the coupling
marked red on the tractor in accordance with regulations.

from the tractor automatically pushes out the button for the re-
lease valve on the trailer brake valve.
9. Remove the wheel chocks.
5.3.2
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.
1. Secure the machine against unintentionally
rolling away. For this purpose, use the
chocks.
2. Release the hose coupling (Fig. 54) of the
supply line (red).
3. Release the hose coupling of the brake line
(yellow).
4. Fasten the hose couplings in the empty
coupling points.
5. Close the covers of the coupling heads on
the tractor.

DANGER
Use the wheel chocks!
Bear in mind that the machine has no parking brake and shows
no braking effect if the compressed air reservoir is empty.
