9. Troubleshooting
In order to prevent damage or serious injury while repairing machine faults, the following points must be observed:
• Only attempt to repair a fault if you have qualified personnel. This means each job must be carried out by trained
specialist personnel, for example electrical work must be performed by a trained electrician.
• Always secure the machine against an accidental restart by disconnecting it from the electric system. Lock out, tag
out, and take appropriate safety precautions.
• Always have a second person make sure the machine is switched off in an emergency.
• Secure moving parts to prevent injury.
• Independent work on the machine is at one‘s own risk and releases the manufacturer from any warranty obligation.
Afin d‘éviter tout dommage ou blessure grave lors de la réparation de la machine, les points suivants doivent être respectés :
• Ne tentez de réparer une défectuosité que si vous disposez d‘un personnel qualifié. Cela signifie que chaque travail
doit être effectué par un personnel spécialisé formé, par exemple, les travaux d’électricité doivent être effectués par
un électricien qualifié.
• Toujours sécuriser la machine contre un redémarrage accidentel en la déconnectant du système électrique. Verrouil-
lez, étiquetez et prenez les mesures de sécurité appropriées.
• Demandez toujours à une deuxième personne de s’assurer que la machine est éteinte en cas d’urgence.
• Attachez les pièces mobiles pour éviter les blessures.
• Toute intervention indépendante sur la machine se fait à ses propres risques et libère le fabricant de toute obligation
au titre de la garantie.
