It means the retractor valve is not working properly. The spring inside mist have been lost. Plz ask the technician to change the retraction valve.

U need to adjust ur compressor to get 30-40 in the gauge showed in the chair. Ask ur technician to adjust ur compressor. And try using little sturdy bottles. Try using mazza 1 lit bottles after cleaning it. It works.

Yes ill see and ill try. - Regards Dr. samuel
