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.
