Note: during working of the oil pump, the pipe may go empty and hence into a vacuumized state. To keep air
out of pressure sensor, pressure sensor must always be filled with hydraulic oil. Please make sure oil outlet is
installed vertically.
If oil has many impurities
pressure sensor outlet might get blocked and pressure may not be detected. Please
select clear oil.
