How to properly remove cylinder?
Tried pumping with my new cylinder tonight. Kept it at 2.5 HG for 5 minutes, and I wanted to stop. I disconnected the pump & hose from the cylinder. Unfortunately, there still was a vaccum. I did not know how to properly remove the cylinder, so I began to pull it away from my body. This made it feel like the pressure was increasing a little bit. As a result, I wanted to be safe, and I slowly would pull it away from my body. After a while I got it off, and right when I removed it, it made a “farting” sound. Is this a safe way to remove the cylinder? I am a pumping newbie, and I do not want to hurt myself. Is there a better method?
Thank You.
