Power supply
When using an extension cable, take care to ensure the minimal cable cross-
section:
Extension cables must be approved for the working environment (e.g. out-
doors) and labelled accordingly.
If a generator is used to supply electricity, the rated power of the generator
must be 2x the rated power of the hand extruder.
