Hello sirs ,i have a soil compactor BC 572 RB and i have an issue with the blade fuction up and down. It has electrohydraulic function ,electonic joystic for dozer and steering function with proportional valves on each site. when i use the joystick to lift up or press down the dozer blade it has no power to lift the blade or when it is at down position it can not lift the machine from ground, it is only do the function when i steer the joystic steering neither to the right or the left. the steering function works ok the pilot pressure is 32bar and at high pressure side is 70 bar when i move the joystick to up position or down and it doesnt move, if move the steeing at the same time holding the up or down position the pressure goes to 230bar and the blade is working as it should. Has anyone come up with a familiar issue? please some advice... thank you
