I don't know what you posted,it shows up in a foreign language for me, but... When I got my Blitz new, it was empty, and wouldn't take a charge. I could hear it hissing out, as my compressor was trying to fill it. I tried every procedure that was recommended until I gave up and was ready to send it back. Then I was given another suggestion. And it worked. I plugged in the fill probe, turned on the compressor, and once it was holding a little air, even while leaking out air.. In full auto cycle the action using the compressors efforts. After a few rips doing this, the gun fixed itself, and started taking a charge. I haven't had any leaks since.
Good luck.
