5 Operation
Additional hydraulic connections on the mast (4th control circuit)
Additional hydraulic connections on the loader unit can be
operated with this function. This function is required if the
standard hydraulic connections are not sufficient for
certain attachments. The rocker switch 47 makes it
possible to change over between the standard hydraulic
connections and the additional hydraulic connections. The
additional hydraulic connections can then also be
operated with control lever 6.
Coupling the additional hydraulic connections requires
releasing the pressure on them first. Proceed as follows
for this:
1. Stop the engine.
2. Switch on the starter (position I).
3. Move the rocker switch to 47 "position I".
4. Operate the control lever 6 repeatedly in both
directions.
➥ The pressure on the additional hydraulic
connections is released.
5. Connect the hydraulic connections of the attachment
