I have a central pneumatic nail gun. the driver doesn't push the nail out and the driver won't return. I can push the driver back manually. Put air to the gun press against a board and the driver comes down but not with any force and it doesn't shoot a nail

The problem is most likely a bad o-ring. This is caused by a lack of lubrication. You can buy kits to repair.
