Trailer Release for Premier #270 Air Pintle Hitch
57x d 19.01.004
- Apply the tractor and trailer parking brakes.
- Chock the front and rear tires of the trailer.
- Disconnect the trailer air and electrical lines. Plug the air lines to keep them free of dirt.
- Take the weight of the trailer drawbar off the pintle hook.
- Pull the pawl out toward the left as far as it will go and then rotate it upward. Holding the pawl in place, rotate the latch upward near the underside of the pawl, then release the pawl. The underside ledge of the pawl will catch the flat front surface of the latch, interlocking the two into the open position.
- Slowly drive the vehicle away from the trailer.
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.
