Problems with my Vario Excavator

[cbazq271]

I tried a the suggestions and I think I got the air out, but the gauge is still not reading the right pressures. You can adjust the pressure limiter and the gauge does not change. I had the gauge showing 25 bars and it blew a hydro line just sitting there running. I am out of ideas. The gauge must be bad. One qustion for those that have a Vario, when you turn the screw one the prssure limiter clockwise, should the pressure go up or down?
