Adjustments and servicing procedures
ADJUSTMENT OF THE CONTINUOUS REGULATING SYSTEM
The working pressure is determined by the tension of
the spring in the regulating valve (RV). This tension
can be increased to raise the pressure and decreased to
lower it by turning the adjusting wheel clockwise and
anti-clockwise respectively.
The solenoid valve (SVa) is only present
at units equipped with a generator
(XA(S) 137 DDG - XA(S) 300 DD7G).
