Intended use
The tool is intended for grinding, sanding and cutting of
metal and stone materials without the use of water.
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 and can, therefore, also be used
from sockets without earth wire.
For public low-voltage distribution systems of
between 220 V and 250 V.
Switching operations of electric apparatus cause
voltage fluctuations. The operation of this device under
unfavorable mains conditions can have adverse effects
to the operation of other equipment. With a mains
impedance equal or less than 0.27 Ohms it can be
presumed that there will be no negative effects. The
mains socket used for this device must be protected
with a fuse or protective circuit breaker having slow
tripping characteristics.
