If the gun stop feeding, you may have to replace the feeding o-ring. It will happen under normal circumstances after a very long use (wearing part). It may also happen in the event of an incident, for exemple when the nozzle sucks up debris. The feeding o-ring will act as a fuse and will protect the rest of the mechanics. Here it's the process to replace this o-ing.
