8.4 Controlling the valves
8.4.1 "Simultaneous operation" control valve (SIMO) ML-630-SI
ATTENTION!
The control levels on the hydraulic power unit should always be switched to the
neutral position (de-pressurised)
prior to starting the engine in order to prevent
unwanted movements of connected hydraulic equipment.
A switching lever that controls the valves (see the top
illustration) is located on the pump block. Both mono-
couplings have been designed in such a way that they
are automatically in the de-pressurised state without
connected device. The control unit on the device
controls the switching when the device is connected.
The switching lever makes it possible to switch to the
"TURBO" function. With this function, one of the two
connections is able to be supplied with double the feed
volume by switching the lever.
The "TURBO" function is activated by turning the large
lever towards the connection that is to be pressurised at the
doubled pumping output.
NOTE:
All switching levers must always be completely switched on up to the end stop.
