- 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.
- Open the latch by removing the lock pin (if equipped), then lift up the lock and raise the latch.
- 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.
