2.2.4 Working on the electrical equipment

• All work on the machine's electrical equipment should be carried out in principle only
by properly qualified skilled electrician personnel.
• During problems with the electrical supply, the installation should be switched off im-
mediately.
• Before starting any work on parts of the installation which are provided with electrical
energy, the installation should be disconnected from the supply and secured against
unexpected reconnection.
• The installation's electrical equipment must be checked regularly. Defects such as, for
example, cable damage, loose connections, etc. should be reported immediately and
made good.
• All personnel not authorised to carry out work on the system's electrical supply must
be barred from access to the interior of the control cabinet.
• The machine's earthing system must not be interrupted. Any earthing wires that have
been removed during maintenance must be replaced before it is switched on again.

2.2.5 Working on the hydraulic equipment

The machine works with the help of hydraulic pressure energy. When dealing with hydrau-
lic energy, there are definite special safety measures to be observed.
• All work on the machine's hydraulic equipment must in principle be carried out only by
properly qualified skilled staff.
• Any system sections or pressure circuits to be opened must be switched to zero pres-
sure before repair work commences.

2.2.6 Residual energy

Bear in mind that after the machine has been switched off or when it is idle, various resid-
ual energies can be present, as, for example,
• in hydraulic pressure lines and pressurised containers
• in live power lines and capacitors.
•
Fluids escaping under high pressure can penetrate the
skin and cause severe injury.
In case of injury by hydraulic fluids, call a doctor
immediately. There is a danger of infection!
