Have a situation, I purchased a Hatsan BT65SB in 177. The O Rings on the fill probe. Caught and ripped on the sides of the fill port. After a lot of trial and error, I was able to fill the gun off of a tank. That now again, I know that. I will need a compressor strong enough to get past 100 bar. Used my compressor to fill to 200 bar, after 90 min the air tube leaked to 70 bar, and over night there was a snap and the air tube is at 0. This all happened in less than 24 hours with my first PCP. After sending a email and leaving a voice mail with hatsan. There has been no response. Should I just submit the RMA, or wait a week?
