Hydraulic control circuits/plug couplings (overview)
The machine has several hydraulic connections depending on the
equipment.
The operation of the hydraulic connections can be found in the following
pages.
In order to avoid leaks on the plug couplings and dirt in the hydraulic oil:
► carefully clean the plug couplings and flexible lines before connecting
them.
► Before connecting the flexible lines, turn off the machine.
The hydraulic system of the machine is still pressurized even when the
machine is switched off. This is why the hydraulic plug couplings can be
released; however, they cannot be re-attached if the pressure in the
hydraulic lines has not been released.
► Release the pressure in the quick coupler
– see "Pressure relief – plug couplings" on page 5-33.
► See the Operator’s Manuals of the attachment manufacturers.
