Hi, I'm new to this forum and also new to airbrush. I just bought a Badger Cyclone II 180-11 and was wondering about the auto shut off feature. When the air is not flowing, is it suppose to completely shut off, as in no noise at all, or does it do the constant short bursts of on/off? Because I get the short bursts which rattles the compressor and I'm afraid I did something wrong. I've read about the hose leaking air, but my doesn't appear to be leaking. I have the braided hose that came with my Athem set. Any help to this noob will be appreciated. Thanks.
