Fasten the test manometer to the high-pressure
connection.
Connect the high-pressure hose and gun to the
test manometer.
Rotate the rotating handle of the pressure regula-
tor on the pump clockwise (direction "+") all the
way to the stop.
Rotate the rotaring regulator on the gun to the po-

Actuate the trigger on the gun and switch on the
appliance.
Pull off the rotary handle on the pressure regula-
tor.
Loosen the locknut of the adjustment screw for
high pressure.
Turn the adjustment screw high pressure until the
opening pressure of the overflow valve of 16.2 to
16.5 MPa (162 to 165 bar) is reached on the test
manometer.
Note
Turn in clock-wise direction to increase the working
pressure.
Turn in counterclockwise direction to decrease the
working pressure.
Secure the adjustment screw for high pressure by
tightening the locknut.
