To ensure that the Safety Valve is working properly, pressurize the instrument and test the Safety Valve. You can see a tutorial on that process here.
If the valve is leaking or not activating properly, you might need to change the Piston O-Ring.
Use a metal probe to remove the O-Ring. Replace with a Size – 006 O-Ring. This should be a Buna-70 hardness. Ensure there is not debris in the O-Ring track. Reinstall and test.
