4.4.1 Checking shut-off valves of the quick couplings
The shut-off valves of the quick couplings automatically seal the
media tanks and the media tubes if both quick coupling parts
are not connected to each other. Check the correct function of
the shut-off valves at every media change.
Press the nipple of the shut-off valve a few millimetres into the
coupling to check the shut-off function. After releasing, the shut-
off valve must spring back outside to the "closed" position
(arrow direction).
The shut-off valve (Fig. 4.4.1.1.F) is moveable and in the not
connected state must be flush with the guide bar
(Fig. 4.4.1.1.G).
