Before Hooking to a Trailer

  • Make sure the trailer does not have a king pin lock in place. If there is a lock, remove it prior to hooking up.
  • Check that fifth wheel is lined up with king pin prior to connecting
  • Check the trailer height and adjust if necessary by lowering the landing gear slightly in a low gear if the trailer is too high or lowering tractor suspension airbags if the trailer is too low.
