You can find out yourself by using compressed air to see how the oil flows. I'm not sure exactly how the dosier works on this fixture manually or automatically. To my understanding it could be both: in manual mode, you can expand the fixture by turning the 调胀紧 screw. if it is applied in automatic mode, the doiser hole is connected to hydraulic supply station, the fixture works when the pressurized oil is pumped in through the doiser hole.
