Coupling the hydraulic hose lines of the Standard hydraulic system

All hydraulic hose lines 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:

IMPORTANT
Implement damage due to hot hydraulic oil
High volume flows in conjunction with small oil tanks promote rapid heating-up of the hydraulic fluid.
The capacity of the oil tank should be at least twice the volume flow.
If the oil heats up too much, have an oil cooler installed by a specialist workshop.
  1. Depressurise the hydraulic system between the tractor and the machine using the tractor control unit.
  2. Clean the hydraulic connectors.
NOTE

If the hydraulic hose lines are incorrectly connected, the hydraulic functions may be faulty.

  1. Couple the hydraulic hose lines 1 to the hydraulic sockets of the tractor according to the marking 2.

The hydraulic connectors lock perceptibly.

  1. If the machine has an upper drawbar:

    Route the hydraulic hose lines through the guide 1.
  2. Route the hydraulic hose lines with sufficient freedom of movement and without chafing points.
