Intended use
The tool is intended for cutting tracks in concrete walls or
cutting in ferrous materials or concrete drainage chan-
nels with a diamond wheel but without using 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 your own safety, please refer to the enclosed safety
instructions.

ADDITIONAL SAFETY RULES

1. Always use eye and ear protection. Other per-
sonal 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
having a maximum operating speed at least as
high as the highest No Load Speed marked on
the tool's name-plate.
5. Check the wheel carefully for cracks or damage
before operation. Replace cracked or damaged

7. Use only flanges specified for this tool.
8. Do not damage the spindle or the flange (espe-
cially the installing surface). Damage to these
parts could result in wheel breakage.
9. 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
immediately if there is any vibration or wobbling
that could indicate poor installation or a poorly
balanced wheel. Check the tool to determine the
cause.
10. Check that the workpiece is properly supported.
11. Hold the tool firmly.
12. Keep hands away from rotating parts.
13. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
14. Do not use cutting off wheel for side grinding.
15. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
16. Pay attention that the wheel continues to rotate
after the tool is switched off.
17. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
18. Position the tool so that the power cord always
stays behind the machine during operation.
19. If working place is extremely hot and humid, or
badly polluted by conductive dust, use a short-
circuit breaker (30 mA) to assure operator safety.
20. Do not use the tool on any materials containing
asbestos.
21. Do not use water or cutting lubricant.
22. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first disconnect
the tool from the mains supply (use non metallic
objects) and avoid damaging internal parts.
23. Cutting discs must not be subjected to any lat-
eral pressure.
