Establishing hydraulic connections
A hydraulic oil supply and control by the towing vehicle are required for all work functions.
Procedure:
Clean the hydraulic connector and hydraulic
socket if necessary.
Connect the plug-in coupling, SVK coupling
size 3, to the correct SVK sleeve on the
towing vehicle and check that it is correctly
engaged.

Coupling:
Before coupling, deactivate the PTO and set the lever on
the control device to neutral position.
-
Ensure that the couplings are clean.
Constant flow:
(1) Pressure connection
(2) Return connection

For more information, refer to section 6.7.
Dual-action control devices required:
Each control circuit features a supply and return coupling
(double-action),
with the exception of the steered trailing axle and hydr. rear panel (single action).
For the assignment of individual hydraulic functions, note the pictogram on the front of
the vehicle (see section 16.1) and the colour coding on the hoses.
