Power supply
The tool should be connected only to a power supply of
the same voltage as indicated on the nameplate, and can
only be operated on single-phase AC supply. They are
double-insulated in accordance with European Standard
and can, therefore, also be used from sockets without
earth wire.

For your own safety, please refer to the enclosed Safety
instructions.
