【Note】
●Use an accurate pressure gauge and inject the specified air pressure little by little.
●When using a compressor, set the pressure regulator to the specified pressure, open the valve slowly, and inject air little by little.
●Injecting air all at once or exceeding the specified air pressure may damage the pressure gauge or deform or rupture the water stop ball, leading to a serious accident.
●Even if it is deformed or damaged, it cannot be repaired.
