Attaching a Kioti Backhoe! Are you having troubles getting the lines to hook up?

I'm really impressed with how easy it is to take off and put on these backhoes. Doesn't take much time at all. I also ran into issues with pressure build up in the hydraulic lines and wanted to talk about it incase anyone else runs into that issue.
