I have a Milwaukee Regulator. I can't get the working pressure to come down. I opened the valve and i'm at 750 psi on thee big gauge and the lower gauge ot is at 130 and i cant get it down to 10 - 15. I screw the know thing and it only goes that low before coming lose and falling off. Or you can go the other way and the working pressure goes up higher and higher but the knob goes back on tighter. I'm scared to mess with this thing. How do I lower it?
Screwing the big knob counterclockwise will lower the working pressure. Screwing it on clockwise will increase the working pressure.
Should I just screw the knob on tighter and ignore the lower gauge?
No, you should not screw the knob tighter. You should screw it looser.
i am NOT touching that anymore. I just scared the s*** out of myself and i'm shaking. I closed the main valve of the co2 cylinder and the main gauge still said 750 psi. But i figured it was closed so it is safe.
If the main gauge still reads 750 PSI after you shut off the valve on the CO2 tank, there is still pressure that the regulator is holding back.
Well i proceeded to tighten the adjustment knob so i can then loosen it up to a low working pressure before the knob came off. Well i did that and the working pressure gauge was still going up till it maxed and a LOUD screech came out and deafened me for a moment. The scariest thing ever. I dont know what i'm doing but this pressurized stuff is scaring me.
You just blew the delivery pressure (working pressure) gauge.
the higher gauge after the scream now with the cylinder valve closed says 0 psi and the lower gauge says the working pressure is 115 psi. I hope I didnt mess anything up big time.
As I mentioned, your low pressure gauge is blown.
Also the water is out of my bubble counter. How do I open it and safely add more water?
You have to ensure that both gauges read 0 before adding more water (or better yet, mineral oil or glycerin) to your counter.
[quote=PRSRocker3390;891687]My solenoid is off, the main cylinder valve is closed. I dont know how to tell if the needle valve is opened or closed and same goes for the adjustment knob.
The needle valve should work on the same principle as the regular valve (though it might be the opposite way...)
Adjustment knobs, however, are the same. Clockwise will increase the working pressure, while counter clockwise will decrease the working pressure.
