Perform the steps relating to the high-pressure operation indicated in the manual relating to
the machine in which the pump is integrated; unless otherwise indicated, in relation to the
pump, the following should be remembered.
a)Resetthedeliverypressure,turningthepressureunloader/regulationvalveinasuitableway.This
condition usually occurs by fully turning the pressure unloader/regulation valve knob counter-
clockwise.
b)Startthepumpandleaveitatresetpressureforafewminutessoastoallowtheoiltoreachthe
correct viscosity and complete pump priming.
c)Settherequiredpressurevaluegradually.Thisisusuallypossiblebyadjustingthepressureunloader/

STOPPING OPERATION
By closing the delivery line, the pump switches to bypass operation and remains in this condition
until the delivery line is opened again.
