7. Troubleshooting

In order to prevent damage or serious injury while rectify-
ing machine faults, the following points must be observed:
Only attempt to rectify a fault if you have qualified person-
nel. 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. Take appro-
priate safety precautions.
Independent work on the machine is at one's own risk and
releases the manufacturer from any warranty obligation.
