I just bought a fill adaptor from the dive shop, i brought my fittings and he made one for me from an old regulator to fill my rifle.It wasn't until i got to about 200 bar that I realized we forgot to put a pressure relief valve on it. now the probe is in the fill port and the tank is full to 225 bar and the scuba tank valve is closed. but no way to release the line pressure. what do i do now? I know, I feel like a complete Idiot. I know better. I dont know how to safely discharge the line to remove the probe from the fill port. please advise.
I have made a serious mistake, I need advice on how to proceed without anyone getting hurt. seriously.

copy that. Thank you for the feedback. I absolutely will add a guage and put this hose onto my normal setup. that was the original idea in fact.
Another question , will it damage the rifle to dry fire on full auto? will it even dryfire in full auto or just semi?
Brand new rifle, hasnt been shot it yet.

Sometimes dry firing can damage an airgun. I'm not familiar with the Blitz, but there has got to be a way to safely degass an air rifle without dry-firing.

I'm not really unsure , I just haven't done it before. Im inexperienced and cautious. i will see what i can learn about the hatsan mechanism and find out if there is a bleeder screw that i can get to with the fill hose attached by a short hose to the tank. the only part I am actually uncertain about is being able to turn any of the valves with 225 bar behind them. the pressure guage on the rifle is not accessible with the stock in place. and the stock cant drop bc the port is on the side, with the probe stuck in it. the tank valve is closed but the yolk valve and airline are charged. When i try to crack that valve seal by loosening the yolk it is too tight, the knob wants to strip.

I dont know... he said they were low pressur ports but im not sure how the regulator works exactly... could i potentially crack one of those screws?

If you loosen one of those screws or a gauge just go slow and when you hear any amount of air escaping stop and walk away to let it slowly leak out. Check it periodically and you might need to open the screw or gauge a bit more. Just make sure the tank valve is turned off.

You're not a complete idiot. I'm sure you've got some parts missing or at least that's what I tell myself when I make a mistake.

just my opinion , do not dry fire in full auto , to risky something could damage itself in the gun ? moving air produces friction / heat .

Can you download pictures in the same format you did the 1st one directly into this thread? I'd like to help but not gonna create a Microsoft account. I'd like to see pics of other end (probe & what gun). I'm thinking, close TANK valve & slowly loosen gauge on your gun's bottle/air tube. Without pictures it's hard to know. I did the same thing the very 1st time I ever filled a pcp and I've worked with HP air for decades! Just got too overexuberant & excited to shoot! Not familiar with your gun. Is there a Pressure gauge on its reservoir?Microsoft OneDrive

The PCP has a check valve inside. The tank valve is closed so the only air that will be released under pressure is inside the fill hose. If you are impatient and won't dry fire the rifle to lower the pressure you can put on hearing protection and just pull the probe out of the rifle. You'll hear a loud pop but the worst that can happen is damaging the o-rings holding the probe in place. I did it once many years ago by unwittingly pulling a probe out without bleeding off the air pressure. The only damage done was soiled underwear!

If you try Humdinger's way make SURE you're wearing work gloves, hearing protection, eye protection, tank valve is closed & you have a FIRM GRIP on probe. Like he said, might blow o-rings on probe but that's no big deal.

Having worked on hundreds of scuba regulators in a dive shop, an easy way to relieve the pressure would be to close the tank valve and then slowly unscrew one of the screws pointed at in post #22. There might be one or two ports on the scuba reg that have HP stamped near the port, it stands for High Pressure, don’t loosen that one, loosen one of the other ones, they only have 130psi under them. Just loosen enough for the O ring to extrude out (along with a startling POP and then brief air release. You can wrap the reg and your allen wrench with several layers of a towel to minimize the POP. You will need a new O ring for that port plug. No big deal.

hey thank you to everyone who helped. It's true you don't know what you don't know... I just wasn't sure and to make a move without knowing in a situation with thousands of psi AND projectiles is pretty irresponsible in my opinion, so i thought I would ask. it did get drawn out, sorry about that. but if you cant help or aren't interested its cool, just don't pay any attention. not everyone knows how to fix a mistake before they make one. I was more pissed I had to ask than anything. if I can ever be of service back, I will be more than happy to oblige. thanks again.

Yeah, solved yet? Solution? Someone else will do it sooner or later. Solution is as important as your original question. Please post how/if you fixed it.

That would work fine. You're only dealing with a small amount of air in the hose, the gun has a check valve, so a small pssst, and you're good to go.
