The woodworking air pump leaks when the pressure is high, and keeps inflating when the pressure is low.

If you haven't inflated the air pump, the air leakage you are talking about is the exhaust of the safety valve. 7 stop inflating. 7Mpa pressure is lower than 0. If it has been adjusted, if the pressure switch fails .00 MPa. For example, the starting pressure should be increased. If the pressure decreases, adjust the screw counterclockwise. If the air pressure exceeds 1, the pressure switch is set to 0, which is higher than 0.5~0. If there is a problem with the adjustment of the pressure switch, the safety valve will adjust the exhaust switch before leaving the factory.
