5.4.2
hydraulically connecting the attachment to the machine
tighten all the hydraulic connections before pressurising the oil.
the oil must be pressurised when the attachment is upright. otherwise air bubbles can form
in the speed valve, which might prevent the upper jaw from opening.
Before hydraulically connecting the attachment to the machine, make sure the following rules are followed:
∂ the machine controls that move the shears must be unmistakably identified;
∂ The hydraulic flows generated by the machine’s hydraulic system must be compatible with the indications
in “4.7.1 hydraulic features” on page 30 ;
∂ the attachment must function if, and only if, the machine is on;
∂ when the machine is switched off, the hydraulic flow towards the attachment must stop;
∂ the machine hydraulic system must not have pressure accumulator tanks, so as to prevent the
attachment from moving unexpectedly;
∂ simply switching on the machine must not result in the attachment moving at all�
The hydraulic connection is differentiated according to the type of hydraulic connection system�
For a hydraulic connection by means of flow regulation blocks refer to
“5.4.2.1 hydraulic connection by
means of flow regulation blocks” on page 48 �
For a hydraulic connection by means of quick-release hydraulic manifolds refer to “5.4.2.2 hydraulic
connection by means of quick-release hydraulic manifolds” on page 51 �

A hydraulic connection by means of flow regulation blocks is differentiated according to the presence or
absence of the drainage line�
