Holland Coupling Trailer Release

sdp dm 17.05.003

    Warning: Do not use the trailer air supply for parking trailers not equipped with spring parking brakes. This applies the trailer service brakes only. As air bleeds from the trailer brake system, brake application is lost. This could allow the unattended vehicle to roll away, possibly resulting in serious personal injury or death.

  1. Apply the tractor and trailer parking brakes.
  2. Chock the front and rear tires of the trailer.
  3. Disconnect the trailer air and electrical lines. Plug the air lines to keep them free of dirt.
  4. Open the latch by removing the lock pin (if equipped), then lift up the lock and raise the latch.
  5. Raise the mating drawbar above the pintle hook. See Fig..
