1. Pressure Relief Valve
2. Pull Ring
The pressure relief valve has no user serviceable or repairable components.
Testing the pressure relief valve
The valve can be tested:
1. On a separate compressed-air system.
2. When raising the system operating pressure to its normal level.
3. Operating the pull ring.
Keep local legislation in mind when testing.
If the pressure relief valve doesn't close itself or is leaky, close the doors of the compressor
and push the Stop Button. After the pressure in the pressure reservoir is reduced to ambient
pressure, renew the pressure relief valve.
