Symbols
The following show the symbols used for the tool. Be sure
that you understand their meaning before use.
............. Read instruction manual.
............. DOUBLE INSULATION
............. Wear safety glasses.
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 in accordance with European Standard
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 unfavor-
able 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.

ADDITIONAL SAFETY RULES

1. Always use eye and ear protection. Other personal
protective equipment such as dust mask, gloves,
helmet and apron should be worn.
2. Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.
3. Keep guards in place.
4. Use only wheels with correct size and wheels hav-
ing a maximum operating speed at least as high as
the highest No Load Speed marked on the tool's
nameplate. When using depressed center wheels,
be sure to use only fiberglass reinforced wheels.
5. Check the wheel carefully for cracks or damage
before operation. Replace cracked or damaged
wheel immediately.
6. Observe the instructions of the manufacturer for
correct mounting and use of wheels. Handle and
store wheels with care.
7. Do not use separate reducing bushings or adap-
tors to adapt large hole abrasive wheels.
8. Use only flanges specified for this tool.
9. Do not damage the spindle, the flange (especially
the installing surface) or the lock nut. Damage to
these parts could result in wheel breakage.
10. For tools intended to be fitted with threaded hole
wheel, ensure that the thread in the wheel is long
enough to accept the spindle length.
11. Before using the tool on an actual workpiece, test
run the tool at the highest no load speed for at
least 30 seconds in a safe position. Stop immedi-
ately if there is any vibration or wobbling that
could indicate poor installation or a poorly bal-
