- 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.
- Rotate the locking pawl toward the mounting plate as far as it will go. Holding the locking pawl in this position, rotate the pawl up until it stops on the locking pawl. Holding the pawl in this position, rotate the latch upward until it stops in the fully open position. Holding the latch open, slowly 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.
