NOTE:
The declared vibration emission value has been
measured in accordance with the standard test method
and may be used for comparing one tool with another.
NOTE:
The declared vibration emission value may
also be used in a preliminary assessment of exposure.
NOTE: The declared vibration emission value is used
for main applications of the power tool. However if the
power tool is used for other applications, the vibration
emission value may be different.
WARNING: The vibration emission during actual
use of the power tool can differ from the declared
emission value depending on the ways in which the
tool is used.
WARNING: Be sure to identify safety measures
to protect the operator that are based on an estima-
tion of exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it is
running idle in addition to the trigger time).

5. Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
6. Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
7. Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
8. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
9. If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
10. Use of power supply via a RCD with a rated
residual current of 30 mA or less is always
recommended.

grinder. Read all safety warnings, instructions,
this power tool. Failure to follow all instructions
2. Operations such as sanding, wire brush-
ing, polishing or cutting-off 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 per-
-
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
5. The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
6. Threaded mounting of accessories must
match the grinder spindle thread. For acces-
Accessories that do not match the
mounting hardware of the power tool will run out of
balance, vibrate excessively and may cause loss
of control.
7. Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks. If power tool or
accessory is dropped, inspect for damage or
install an undamaged accessory. After inspect-
ing and installing an accessory, position your-
self and bystanders away from the plane of
the rotating accessory and run the power tool
at maximum no-load speed for one minute.
Damaged accessories will normally break apart
during this test time.
8. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments.
The eye protection must be capable of stopping
The dust mask or respirator must be capable of
cause hearing loss.

10. Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
11. Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
12. Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
Do not run the power tool while carrying it at
your side. Accidental contact with the spinning

16. Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
rotating accessory which in turn causes the uncon-
trolled power tool to be forced in the direction opposite
of the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel that is
entering into the pinch point can dig into the surface of
the material causing the wheel to climb out or kick out.
operator, depending on direction of the wheel’s move-
ment at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
5ENGLISH
a)
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kick-
back forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite
to the wheel’s movement at the point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades create
frequent kickback and loss of control.
a) Use only wheel types that are recommended
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
b) The guard must be securely attached to the
power tool and positioned for maximum safety,
so the least amount of wheel is exposed
towards the operator. The guard helps to protect
the operator from broken wheel fragments, acci-
dental contact with wheel and sparks that could
ignite clothing.
c)
are of correct size and shape for your selected
wheel.
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
d) Do not use worn down wheels from larger
power tools. Wheel intended for larger power tool
is not suitable for the higher speed of a smaller
tool and may burst.
Additional safety warnings:
17. Never use depressed center wheels or abra-
sive cut-off wheels.
18. Be careful not to damage the spindle, the
lock nut. Damage to these parts could result in
wheel breakage.
19. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
20. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
21. -
form the grinding.
22. Do not leave the tool running. Operate the tool
only when hand-held.

burn your skin.
24. Observe the instructions of the manufacturer
for correct mounting and use of wheels.
Handle and store wheels with care.
25.
26. Check that the workpiece is properly
supported.
27. Pay attention that the wheel continues to
rotate after the tool is switched off.
28. If working place is extremely hot and humid,
or badly polluted by conductive dust, use a
short-circuit breaker (30 mA) to assure opera-
tor safety.
29. Do not use the tool on any materials contain-
ing asbestos.
