OPERATING MANUAL

Safety valve
The safety valve (10) has been factory adjusted so as to ensure that if pressure exceeds the
permitted operating pressure, the valve, which is held with a spring, automatically opens
and releases the excess pressure.
As well as handling pressure limits, the valve is also used as a pressure relief valve for the
air motor.
5.4.3 SAFETY AND MOTOR PRESSURE RELIEF VALVE
Pressure relief of the air motor:
1 Close ball valve (2).
2 Pull back the ring on the safety
valve (10) and hold it there until
the pressure in the air motor has
been equalized.
Overpressure!
Risk of injury from bursting components.
Never change the safety valve setting.
WARNING
So that the complete pressure relief of the pump can be
performed (see Chapter 7.2.2), the installation of a return
valve is mandatory.
The suitable return valves (ball valves), return pipes and hoses
for the device can be found in the accessories list.
