Close air-supply ball-valve without relieving and checkfor pressure-loss.1. Check for leaks at air piston by listening for leaking at exhausts with gun closed in bothupwards and downwards directions.2. Check for leaks at air piston by listening for leaking at exhausts with gun closed in bothupwards and downwards directions.3. Check flange seals.4. Check air connections to pilot valve.5.
