Fasten the test manometer to the high-pressure con-
nection.
Connect the high-pressure hose and gun to the test
manometer.
Install the
new
high pressure nozzle.
Completely open the control knob on the gun (turn to-
wards "+").
Actuate the trigger on the gun and switch on the appli-
ance.
Rotate the rotating handle of the pressure regulator on
the pump anti-clockwise (direction "-") all the way to the
stop.
Pull off the rotary handle on the pressure regulator.
Loosen the locknut of the adjustment screw for low
pressure.
Turn the adjustment screw low pressure together with
the spindle until the minimum working pressure of the
overflow valve is reached on the test manometer (see
technical data, partial load).
Note
If this screw is turned clockwise, the pressure is increased;
and if it is turned counter-clockwise, the pressure is de-
creased.
Secure the adjustment screw for low pressure by tight-
ening the locknut.
Check the working pressure, feed volume and switch
points of the pressure switches.
Then seal this setting.
Note
With minimum pressure and volume adjustments and
when using the supplied steam nozzle, the pressure must
not exceed 32 bar.
