Original problem was leaking off tilt cylinders found both tilt cylinders bad also pump had low pressure. New pump ,new control valve, rebuilt tilt cylinders, full of hydraulic fluid and all pressures are correct lifts up slow goes down fine. No tilt back unless you rev up engine or dead head lift or aux at same time as tilt back its the same with aux. Also tilt forward is slow unless motor reved up don't use aux function but it is on lift from factory.
Have tried to recalibrate not working or iam doing it wrong any help would be greatful before i callin a tech again Tks David
