Electrical hazards
• Work on the electrical power supply should be carried out by trained
electricians only.
• The electrical equipment of the machine must be checked regularly.
Repair any loose connections and damaged cables immediately.
• The power supply unit must always remain closed. It may only be
opened by authorised personnel.
• An explosive atmosphere must be avoided, as the electrical compo-
nents are not explosion-proof.
Maintenance and repair, troubleshooting
• The intervals specified for the prescribed maintenance and repair work
must be observed.
• The operating personnel must be informed before any maintenance
and repair work is started.
• Before commencing maintenance, inspection and repair work, care
must be taken to ensure that the machine is de-energised and that the
main switch cannot be switched on again inadvertently.
A warning sign must be put in place to prevent the machine from being
started by a third party.
• When replacing large assemblies, carefully attach and secure them to
the lifting gear.
• Check loosened screw connections to ensure that they are secure.
• Once the maintenance work has been completed, check to ensure that
the safety devices are fitted and are functioning correctly.
