THEORETICAL PNEUMATIC SPRINGS WORKING PRESSURETo be individually adjusted in order to obtain the full planarity of the mill basament and a min. clearance "C" of 15 mm (0+5mm)between the safety pads and the mill basement lower beams between the safety pads and the mill basement lower beams low pressure alarm set:lower the pressure until the clearance "C" becomes 10 mm.Read the relevant pressure on the pneumatic panel and set the "LOW PRESSURE ALARM" at said value
