21 TROUBLE SHOOTING
Danger due to electrical voltage! Manipulating the machine with the power supply
up may result in serious injury or death. Before carrying out any troubleshooting
work, always disconnect the machine from the power supply and secure it against
unintentional recommissioning.
Many possible sources of error can be excluded in advance if the machine is properly connected
to the mains.
If you are unable to carry out necessary repairs properly and/or do not have the required
training, always consult a specialist to solve the problem.
