Explanation: During the express delivery process, the slider inside will shift and need to be reset manually. The specific operation method is as follows: Open the air valve cover, move the two small black sliders back and forth, one on the left and the other on the right, and then install the air valve cover（There is no need to tighten the air valve cover screws too tightly）
Explanation: Compressed air contains impurities and moisture. Over time, the impurities will accumulate more and more in the valve chamber, which will wear the V-ring and O-ring inside, causing the pneumatic diaphragm pump to not work; Adjust the intake pressure to avoid excessive pressure damaging the diaphragm; the added oil can lubricate the valve chamber.
Explanation: The pressure of the air source is too high, which causes the diaphragm to be broken; the inlet is blocked or the valve is installed, which causes the vacuum in the pump cavity to cause the diaphragm to rupture.
