Do not dispose of electric equipment
together with household waste
material!
In observance of European Directive
2002/96/EC on waste electric and
electronic equipment and its
implementation in accordance with
national law, electric equipment that
have reached the end of their life
must be collected separately and
returned to an environmentally
compatible recycling facility.
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 unfavora-
ble 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.
For European countries only
Noise and Vibration
The typical A-weighted noise levels are
sound pressure level: 90 dB (A)
sound power level: 103 dB (A)
– Wear ear protection. –
The typical weighted root mean square acceleration
value is not more than 2.5 m/s2.
These values have been obtained according to
EN50144.
EC-DECLARATION OF CONFORMITY

SAFETY INSTRUCTIONS ENA001-2
WARNING:
When using electric tools, basic safety precautions, including the following,
should always be followed to reduce the risk of fire, electric shock and
personal injury. Read all these instructions before operating this product
and save these instructions.
For safe operations:
1. Keep work area clean.
Cluttered areas and benches invite injuries.
2. Consider work area environment.
Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work
area well lit. Do not use power tools where there is
risk to cause fire or explosion.
3. Guard against electric shock.
Avoid body contact with earthed or grounded sur-
faces (e.g. pipes, radiators, ranges, refrigerators).
4. Keep children away.
Do not let visitors touch the tool or extension cord.
All visitors should be kept away from work area.
5. Store idle tools.
When not in use, tools should be stored in a dry,
high or locked up place, out of reach of children.
6. Do not force the tool.
It will do the job better and safer at the rate for which
it was intended.
7. Use the right tool.
Do not force small tools or attachments to do the job
of a heavy duty tool. Do not use tools for purposes
not intended; for example, do not use circular saws
to cut tree limbs or logs.
8. Dress properly.
Do not wear loose clothing or jewellery, they can be
caught in moving parts. Rubber gloves and non-skid
footwear are recommended when working outdoors.
Wear protecting hair covering to contain long hair.
9. Use safety glasses and hearing protection.
Also use face or dust mask if the cutting operation is
dusty.
10. Connect dust extraction equipment.
If devices are provided for the connection of dust
extraction and collection facilities ensure these are
connected and properly used.
11. Do not abuse the cord.
Never carry the tool by the cord or yank it to discon-
nect it from the socket. Keep the cord away from
heat, oil and sharp edges.
12. Secure work.
Use clamps or a vice to hold the work. It is safer
than using your hand and it frees both hands to
operate the tool.
13. Do not overreach.
Keep proper footing and balance at all times.
14. Maintain tools with care.
Keep cutting tools sharp and clean for better and
safer performance. Follow instructions for lubrica-
tion and changing accessories. Inspect tool cord
periodically and if damaged have it repaired by an
authorized service facility. Inspect extension cords
periodically and replace, if damaged. Keep handles
dry, clean and free from oil and grease.
15. Disconnect tools.
When not in use, before servicing and when chang-
ing accessories such as blades, bits and cutters.
16. Remove adjusting keys and wrenches.
Form the habit of checking to see that keys and
adjusting wrenches are removed from the tool
before turning it on.
17. Avoid unintentional starting.
Do not carry a plugged-in tool with a finger on the
switch. Ensure switch is off when plugging in.
18. Use outdoor extension leads.
When tool is used outdoors, use only extension
cords intended for outdoor use.
19. Stay alert.
Watch what you are doing. Use common sense. Do
not operate tool when you are tired.
20. Check damaged parts.
Before further use of the tool, a guard or other part
that is damaged should be carefully checked to
determine that it will operate properly and perform
its intended function. Check for alignment of moving
parts, free running of moving parts, breakage of
parts, mounting and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or replaced
by an authorized service center unless otherwise
indicated in this instruction manual. Have defective
switches replaced by an authorized service facility.
Do not use the tool if the switch does not turn it on
and off.
21. Warning.
The use of any accessory or attachment, other than
those recommended in this instruction manual or
the catalog, may present a risk of personal injury.
22. Have your tool repaired by a qualified person.
This electric tool is in accordance with the relevant
safety requirements. Repairs should only be carried
out by qualified persons using original spare parts,
otherwise this may result in considerable danger to
the user.

ADDITIONAL SAFETY RULES ENB031-6
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 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 (espe-
cially 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
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.
12. Check that the workpiece is properly supported.
13. Hold the tool firmly.
14. Keep hands away from rotating parts.
15. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
16. Use the specified surface of the wheel to per-
form the grinding.
17. Do not use cutting off wheel for side grinding.
18. Watch out for flying sparks. Hold the tool so that
sparks fly away from you and other persons or
flammable materials.
19. Pay attention that the wheel continues to rotate
after the tool is switched off.
20. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
21. Position the tool so that the power cord always
stays behind the machine during operation.
22. 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.
23. Do not use the tool on any materials containing
asbestos.
24. Do not use water or grinding lubricant.
25. Ensure that ventilation openings are kept clear
when working in dusty conditions. If it should
become necessary to clear dust, first discon-
nect the tool from the mains supply ( use non
metallic objects ) and avoid damaging internal
parts.
26. When use cut-off wheel, always work with the
dust collecting wheel guard required by domes-
tic regulation.
27. Cutting discs must not be subjected to any lat-
eral pressure.
