Couple unbraked trailers - Step by step

  1. To begin, please remove the wheel chocks from the trailer and push these into the holder on the trailer until they click-in.

  2. Please ensure always that the drawbar coupling is not worn or dirty before commencing your journey.

  3. Pull the handle of the drawbar coupling completely up.

  4. Place the drawbar coupling on the towball of the towing vehicle and simultaneously wrap the arrestor cable around the ball neck.

  5. With sufficient drawbar load, the drawbar coupling snaps into place independently. If not then press down on the drawbar coupling until it snaps into place.

  6. Make sure that the safety display lies in the green/positive area. For safety, carry out a lifting test.

  7. Plug-in the trailer cable to the socket on the towing vehicle in order to create an electrical connection. Then ensure that the lighting systems are in full operation.

  8. Test the backlights, load, finish.

  • Disconnect the electrical connection to the towing vehicle and secure the plug in the corresponding holder on the trailer.
  • Pull the handle on the towbar coupling upward and remove the arrestor cable from the towball of the towing vehicle. Then lift the towbar coupling off the towball, leaving the handle open while doing so.
