Danger
Prior to all work on the appliance, switch off the appliance
and pull the power plug.
* The control valve switches off the electric motor by
means of the pressure surge that is created when closing
the hand spray gun. Subsequently, the control valve ef-
fects a pressure reduction to 30...40 bar. In this way, the
pump and accessories are protected and the force for
opening the hand spray gun is reduced. For pumps that
are equipped with this control valve, the pressure cannot
be regulated on the hand spray gun (Servopress).
