Pressure relief – plug couplings
Information
The hydraulic system of the machine is still pressurized even when the
machine is switched off!
The hydraulic plug couplings can be released, however they cannot
be re-attached because the pressure in the hydraulic lines has not been
released. Release the pressure in the sections of the system and
hydraulic lines that are to be opened before installing and removing an
attachment.
