Hydro:
red
Permanent oil circulation
single-
acting
red
Pressure-free return flow
red
Load-Sensing-control line
(where required / settings on the hydraulic block)
Maximum permissible pressure in oil return: 10 bar
Therefore do not connect the oil return to the tractor control unit, but
to a pressure-free oil return flow with a large plug coupling.
WARNING
For the oil return, use only DN16 lines and select short return
paths.
Pressurise the hydraulic system only when the free return has
been correctly coupled.
Install the coupling union (supplied) on the pressure-free oil return
flow.
WARNING
Danger of infection from escaping hydraulic fluid at high pres-
sure!
When coupling and uncoupling the hydraulic hose lines, ensure that
the hydraulic system is depressurised on both the machine and trac-
tor sides.
If you are injured by hydraulic fluid, contact a doctor immediately.
5.9.1 Coupling the hydraulic hose lines
WARNING
Danger from faulty hydraulic functions in event of incorrectly
connected hydraulic hose lines!
