WARNING
Risk of infection from hydraulic fluid escaping at high pressure.
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.
Oil return flow
Profi-folding:
Maximum permissible pressure in oil return: 5 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.
