Generation of pressure

First, check whether the change-over valve (4) has to be actuated (see
sticker on the device). For this purpose use a pen or a small screw-driver.
The encasement of the switch is intended to help prevent unintentional
actuation.
Never actuate the change-over valve (4) when the hand test
pump is under pressure or vacuum! Actuate the change-over
valve only when the relief valve is open.
Please make sure that the pressure relief valve (3) is not closed
completely.
Turn the fine adjustment valve (2) anticlockwise up to the end (smooth
stop can be felt).
