TROUBLESHOOTING
Danger due to electrical voltage!
Handling the machine with connected power supply may result in serious injury or
death.
Always disconnect the machine from the power supply before starting work to
repair defects and secure it against unintentional reconnection.
Many possible sources of error can be eliminated in advance if the machine is properly connected
to the power supply. If you are unable to carry out the necessary repairs properly and/or do not
have the required training, always consult a specialist to solve the problem.
