5.4 Safety valve

Operating

Operate the safety valve by unscrewing the knurled cap one or two turns. Retighten the cap.

Testing

The valve can be tested on a separate compressed air line. If the valve does not open at the pressure
marked on the valve, consult Atlas Copco.

Warning

No adjustments are allowed. Never run the compressor without safety valve.
