DANGER!
Mains voltage
- Before starting servicing work, unplug the device and
protect it from restarting accidentally!
- Indicate servicing work using a warning sign.
- Only have servicing carried out by skilled personnel.
- Put safety equipment back into operation after
servicing and repair work.
- We recommend keeping a safety logbook into which
all work (servicing, repairs etc.) to the device are
entered.
- The most important element of servicing is regular
cleaning:
- Cleaning of the entire device must observe the
regulations of the employer’s liability insurance
associations (BGV A3)
– in particular when the device
is positioned in a dusty environment or dusty sample
material is processed.
