5 Adjustments and servicing procedures
5.1 Adjustment of the continuous regulating system
The working pressure is determined by the tension of the spring in the regulating valve (1). This
tension can be increased to raise the pressure and decreased to lower it by turning the adjusting
wheel clockwise and anti-clockwise respectively.
To adjust the normal working pressure, proceed as follows:
1 Loosen the lock nut of the regulating valve (1).
2 Release Regulating Valve (turn out).
3 With the outlet valves (2) closed, adjust the regulating valve (1), until a pressure is reached of
nominal pressure + 2 bar (+ 29 psi).
4 Lock the regulating valve (1) by fixing the lock nut.
