An I using in-cab kingpin release valve wrong?

I love mine. But there is learning curve to them.
1) don't yank on it pull it out slow and steady.
2) make sure your air tanks are full
3) you want to be on as level ground as possible
4) have you tried pulling the release on the fifth wheel by hand. Almost in possible.
5) it will not just open/realease the fifth wheel while moveing. Unless the saftey sensor is by passed.
6) it will remind you to drain the moisture out of the tanks. Once that thang freezes up. Thats when i hate it.
