5. Locking indicator pin (A) fully level with the front: coupling safe.
6. If the locking indicator pin (A) is not entirely level with the front, the coupling is
not safe and you must couple the trailer again.
7. When coupling, check the coupling head rubbers of the air pipes of both the
prime mover and the trailer vehicle for any damage.
8. Connect the brake pipes and the cables for the lighting and ABS/EBS.
Uncoupling
1. Put wheel chocks in front and behind the trailer's rigid axle wheels.
2. Be absolutely certain that the trailer is braked.
3. Detach the brake pipes and cables for lighting and ABS/EBS.
4. The trailer vehicle coupling can only be opened in the centre position or the two
outer positions of the coupling jaw. (If the coupling jaw is crooked, the coupling
pin cannot be unlocked!)
5. Pull the lever up and drive the vehicle away.
