Damage
If any damage occurs during operation and makes it impossible to continue work safely, work must be stopped
and the defect must be corrected.
The correction of small defects, such as for example the replacement of fuses, can quickly be carried out on-site
if the appropriate spare part is available, but must only be performed by a trained service technician. Please
note that the equipment must be switched off to do so.
The equipment must be switched off and the emergency stop button must be pressed prior to any work on
electrical components. Then, disconnect the equipment from the power supply.

Never work on equipment which may be connected to a power supply. Make sure that the power supply of
the equipment is unplugged and secured against accidental switch-on, prior to any work taking place.
