Intended use
The tool is intended for grinding, sanding and cutting of
metal and stone materials without the use of water.
ENF002-1
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.
ENF100-1
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 unfavor-
able mains conditions can have adverse effects to the
operation of other equipment. With a mains impedance
equal or less than 0.24 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.

Safety Warnings Common for Grinding, Sanding,
Wire Brushing, or Abrasive Cutting-Off Operations:
1.
This power tool is intended to function as a
grinder, sander, wire brush or cut-off tool. Read
all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below may
result in electric shock, fire and/or serious injury.
2. Operations such as polishing are not recom-
mended to be performed with this power tool.
Operations for which the power tool was not
designed may create a hazard and cause personal
injury.
3. Do not use accessories which are not specifi-
cally designed and recommended by the tool
manufacturer.
Just because the accessory can be
attached to your power tool, it does not assure safe
operation.
4. The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool.
Accessories running faster than
their rated speed can break and fly apart.
5. The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool.
Incorrectly sized accessories can-
not be adequately guarded or controlled.
6. The arbour size of wheels, flanges, backing pads
or any other accessory must properly fit the
spindle of the power tool.
Accessories with arbour
holes that do not match the mounting hardware of
the power tool will run out of balance, vibrate exces-
sively and may cause loss of control.
