Hi my regulator doesn't seem to respond electronically. Even when it is unplugged the bubbles still come out, is it broken?

Also what are the correct procedures when installing the regulator on the Co2 tank? I remember there were instructions of loosening the knob...... I lost the instructions, please if anyone knows tell me.

Thankss

I just had the same problem. Try turning it on and off couple of times might unstuck the solenoid.I called the people @ milwalkee and they told me to take the solenoid piston body apart and lube the plunger assy with wd40??? IMO anything that goes on the actual plunger will go into the co2 stream and into the tank oh well. I used food grade silicone spray and it's still screwed up. I ended up changing out with a clippard solenoid from Rex. It works fine and at least I have some peace of mind now. Hopefully milwalkee will repair it,but I'd probably not use it.Call milwalkee and see what they say. Also when when removing or installing the regulator turn off the main valve on the tank and make sure to back the black knob on the regulator all the way out till it's really loose. Then you can turn the tank valve on and slowly turn the black knob in till you get the output pressure you desire. IMO I wouldn't go over 40psi (right gauge) others might crank their's up more but I found that 25psi works good for me.

^^^ What he said, do a search here, people have had your problem before.

Also, remember that you should never have the black knob turned all the way clockwise as this would damage the diaphragm. Turn the knob all the way CCW until its almost going to fall off and close the needle valve. Main valve off, then connect the regulator, main valve all the way open, then black knob CW until right gauge reads ~20, then slowly open needle valve (only a slight turn will get it going).

This is a copy and paste from REX's" co2 stuff for sale" section:

" Please note that these needle valves are NOT shut off valves and using them as such will damage them to the point where they no longer function. "

You can turn it until it feels slightly tightened /closed.

That for the Clippard needle valves that I sell. Some needle valves can function as shutoff valves.
