1. Before installing the pressure reducer, slightly open the cylinder valve to blow down the dirt to prevent dust and moisture from entering the pressure reducer before installing the pressure reducer. When opening the cylinder valve, the operator should not stand in front of the outlet of the cylinder valve to prevent the sudden rush of high-pressure gas from hurting people.



2. The pressure regulator screw should be loosened before opening the cylinder valve. When opening the cylinder valve, it should be done slowly and not too hard to prevent high pressure gas from damaging the pressure reducer and pressure gauge.



3. After opening the cylinder valve, check for air leakage in all parts. Whether the pressure gauge is working properly, the hose should be connected after checking.



4. When adjusting the working pressure, the pressure regulating screw should be rotated slowly. To prevent high-pressure gas from breaking diaphragm or damaging low-pressure meter



5. Pressure reducer should not be contaminated with grease. If there is any grease, it must be controlled and cleaned before it can be used.



6. In the course of using the pressure reducer, if freezing occurs, thaw it with hot water or steam, and do not bake it by fire.



7. When stopping working, the bottle valve should be closed and the gas in the pressure reducer should be slowly exhausted, and the pressure regulating spring should be kept in its own state.



8. Pressure reducers must be checked regularly and pressure gauges must be checked regularly to ensure reliable pressure regulation and accurate reading.



9. Oxygen and acetylene decompressors are not interchangeable



10. The working pressure of 10 acetylene depressor should not be greater than 0.1 MPa
