Execute a check that is visual the fifth wheel jaws have actually involved precisely and fit the safety “dog clip” or any other security unit. Execute a 2nd test that the fifth wheel jaws have actually involved by choosing a minimal ahead gear along with the trailer brake system still applied gradually pulling ahead. Apply the tractor unit parking braking system, stop the motor and take away the tips. Link the solution flight (yellow) and connections that are electrical. Link the crisis flight (red) and watch out for any unexpected motion. ( If the trailer moves, immediately disconnect the crisis flight (red) and look that the trailer parking brake happens to be used. Crank up the landing feet and secure the handle.
