Before use, it is necessary to exhaust the air, as follows:

1. Open the cover of the upper pump oil cup (the upper pump is fixed in the faucet state)

2. Repeatedly pinch the brake handle of the pump more than ten times, then hold it tightly, then loosen the oil drain screw of the lower pump, and repeat the operation until there is pressure on the brake handle. If the handle is too soft and there is no pressure, proceed to the next step.

3. Open the air exhaust screw on the lower pump. At this time, do not pinch the handle. Oil will flow out of the air exhaust screw hole, and at the same time, bubbles will also come out (the oil cup of the upper pump should not be short of oil in this operation step). When no bubbles are visible, tighten the air exhaust screw.

4. If the effect is not obvious, repeat 2 and 3
