For the proper operation of the machine, 300 to 500 litres of air should be drawn in per minute.
Check the pressure-gauge on the FRL air input unit (Filter Pressure Reducer Lubricator), which should remain within a range of 6 to 8 bar.
为保证机器的正常运转，每分钟需要输入300到500升的空气。
查看FRL(滤波减压器润滑剂)空气输入设备上的压力计，应该维持在6~8个大气压之内。
