Blah, ignore them
What happened is you blew your low pressure relief valve. You just have to replace the brass thingy that blew and make sure your gauge isnt' busted (spring will be uncoiled if it is...replace it if such is the case). This is what happens when you turn up your Maxflow too high-- the brass plug busts so that your solenoids don't blow, which would be more expensive and difficult to replace.
Now that you know what is going on, you want to prevent this from happening again. Basically the way to keep it from happening is to not screw the Maxflow cap on very far after having taken it off or stopped playing. There should be an aluminum ring that stops the cap at the end. DO NOT MOVE THIS UNLESS AT THE CHRONO. Your gun should never have more than 195 psi input, as over it will wear on and/or blow your relief plug or your solenoids. Unfortunately you can't tell what your pressure is unless you turn on the gas; hence if you have it set right during the day's play DON'T TURN IT DOWN AND FOR GOD'S SAKE NEVER TURN IT UP WITHOUT KNOWING WHAT IT IS GOING TO BE.
Simple problem, simple solution. Class dismissed.
