  1. Chock the front and rear tires of the trailer.
  2. 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. See Fig..

  3. Back up the vehicle until the drawbar eye is over the pintle hook.
  4. Lower the trailer, until the drawbar eye rests on the pintle hook.
  5. Rotate the pawl toward the mounting plate to the fully open position, releasing the latch. The latch should rotate downward by itself until stopped by the pintle. Release the pawl to rotate down and engage the latch at its matching machined face. The locking pawl will rotate down into the recessed pocket of the pawl.

    6. Notice: Always make sure the connection hanger keeps the trailer air hoses and electrical cables positioned so that they do not rub on anything. Rubbing may wear through hoses or cables, resulting in air leaks, or exposed or broken wires, potentially affecting trailer brake or electrical systems.

    Note: Verify proper latching by applying upward force to the bottom of the latch. There should only be minimal movement and the latch should not open. If the pawl or latch does not stay closed, do not use until it has been repaired or replaced.

  6. Connect the trailer electrical and air lines.
