Coupling the hydraulic hose lines

All hydraulic hoses are equipped with handles. The handles have colour markings with a code number or a code letter. The markings are assigned to the respective hydraulic functions of the pressure line of a tractor control unit. Stickers are applied on the machine for the markings, which illustrate the respective hydraulic functions.

The tractor control unit is used with different types of actuation, depending on the hydraulic function:


Type of actuation	Function	Symbol
Latching	Permanent oil circulation
Momentary	Oil circulation until action is executed
Floating	Free oil flow in the tractor control unit


Designation	Function			Tractor control unit
Red	Pressure-free return flow. The pressure-free return flow must always be coupled!			Maximum line pressure less than 5bar
		Fan hydraulic motor	Switching on	Single-acting
		Coulter pressure	Increase Reduce	Single-acting
Green		Section	Extend Retract	Double-acting
Yellow		Track marker	Lifting	Single-acting
Blue		Frame ballasting	Increase Reduce	Double-acting
Beige		Filling auger	Switching on	Single-acting

If there not enough available tractor control units, multiple machine functions 2 can be assigned to one tractor control unit with the Comfort hydraulic system. The function is actuated either via the machine software or via ComfortClick 1.

Depressurise the hydraulic system between the tractor and the machine using the tractor control unit.
Clean the hydraulic plugs.

IMPORTANT

Implement damage due to insufficient hydraulic oil return flow

On the tractor side, only use lines that correspond to the nominal width of red T of the implement or larger for the pressureless hydraulic oil return flow.

Select short return paths.

Connect the pressureless hydraulic oil return flow to the intended coupling before all of the other hydraulic connections.

If the implement has a leakage oil line:

couple the leakage oil line in the intended coupling.

Install the supplied coupling sleeve on the pressureless hydraulic oil return.

First couple the red T hydraulic hose line with the corresponding hydraulic socket on the tractor.
Couple the red 1 hydraulic hose line with the corresponding hydraulic socket on the tractor.
Couple the remaining hydraulic hose lines 1 to the hydraulic sockets on the tractor according to the marking 2.

The hydraulic plugs lock perceptibly.

Route the hydraulic hose lines with sufficient freedom of movement and without chafing points.
To warm up the hydraulic oil for optimal regulation of the hydraulic system:
Run the fan for a few minutes at 2.5001/min.
