1. Adjustment of pressure level: Turn the pressure adjustment screw 1 clockwise to increase the applied pressure, and vice versa to decrease the applied pressure, but the pressure difference remains unchanged

　　2. Adjustment of pressure level: Turn the pressure adjustment screw 2 clockwise to increase the applied pressure, and vice versa to decrease the applied pressure, but the pressure difference remains unchanged

　　3. When the air compressor reaches the set pressure, the saturation and relief valves will discharge the gas inside the steel pipe, which is a normal phenomenon and not a leakage

　　4. 1-2 adjustment screws are interrelated

　　5. Adjust the pressure to ensure that it exceeds the discharge pressure of the compressor
