How does a fifth wheel work on a semi? We managed to hook it up okay, but I don't know how to uncouple the trailer. It has an air-operated release. How do you use one?

There should be both the air and a hand release for the fifth wheel. Usually the parking (Spring) brakes must be on for the air release to work. That keep you from accidentally dropping your trailer when moving.
