5.1 Safety warnings common for grin-
ding or abrasive cutting-off opera-
tions
• Thispowertoolisintendedtofunctionasa
grinder or cut-off tool. Read all safety war-
nings, instructions, illustrations and specifi-
cations provided with this power tool. Failure
to follow all instructions listed below may
result in electric shock, fire and/or serious
injury.
• Operations such as sanding, wire brushing
or polishing are not recommended to be per-
formed with this power tool. Operations for
which the power tool was not designed may
create a hazard and cause personal injury.
• 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.
• 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.
• 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.
• Thearboursizeof wheels,flanges,backing
pads or any other accessory must properly
fit the spindle of the power tool. Accessories

47
with arbour holes that do not match the
mounting hardware of the power tool will run
out of balance, vibrate excessively and may
cause loss of control.
• Donotuseadamagedaccessory.Beforeeach
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad
for cracks, tear or excess wear, wire brush
for loose or cracked wires. If power tool or
accessory is dropped, inspect for damage
or install an undamaged accessory. After
inspecting and installing an accessory, posi-
tion yourself 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.
•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 stop-
ping flying debris generated by various ope-
rations. The dust mask or respirator must be
capable of filtrating particles generated by
your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
• Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken acces-
sory may fly away and cause injury beyond
immediate area of operation.
• Hold power tool by insulated gripping sur-
faces 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
shock the operator.
• 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.
• Never lay the power tool down until the
accessory 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 accessory could snag your clothing,
pulling the accessory into your body.
• Regularly clean the power tool’s air vents.
Themotor’sfanwilldrawthedustinsidethe
housing and excessive accumulation of pow-
dered metal may cause electrical hazards.
• Do not operate the power tool near flam-
mable materials. Sparks could ignite these
materials.
• Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
5.2 Kickback and related warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush
or any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled 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. The wheel may
either jump toward or away from the 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 con-
ditions and can be avoided by taking proper
precautions as given below.
• Maintainafirmgripon thepower tooland
position your body and arm to allow you to
resist kickback forces. Always use auxiliary

48
handle, if provided, for maximum control
over kickback or torque reaction during start-
up. The operator can control torque reactions
or kickback forces, if proper precautions are
taken.
• Never place your hand near the rotating
accessory. Accessory may kickback over
your hand.
• 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.
• Use special care when working corners,
sharp edges etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating
accessory and cause loss of control or kick-
back.
• Donotattachasawchainwoodcarvingblade
or toothed saw blade. Such blades create fre-
quent kickback and loss of control.
5.3 Safety warnings specific for grinding
and abrasive cutting-off operations
• Useonlywheeltypesthatarerecommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed can-
not be adequately guarded and are unsafe.
• The guard must be securely attached to the
power tool and positioned for maximum
safety, so the least amount of wheel is expo-
sed towards the operator. The guard helps
to protect operator from broken wheel frag-
ments and accidental contact with wheel.
• Wheelsmustbeusedonlyforrecommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding,
side forces applied to these wheels may cause
them to shatter.
• Always use undamaged wheel flanges that
are of correct size and shape for your selec-
tedwheel.Properwheelflangessupportthe
wheel thus reducing the possibility of wheel
breakage. Flanges for cut-off wheels may be
different from grinding wheel flanges.
• 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.
5.4 Additional safety warnings specific
for abrasive cutting-off operations
• Do not “jam” the cut-off wheel or apply
excessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing the
wheel increases the loading and suscepti-
bility to twisting or binding of the wheel in
theDonot“jam”thecut-offwheelorapply
excessive pressure. Do not attempt to make
an excessive depth of cut. Overstressing the
wheel increases the loading and susceptibility
to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel brea-
kage.
• Donotpositionyourbodyinlinewithand
behind the rotating wheel. When the wheel,
at the point of operation, is moving away
from your body, the possible kickback may
propel the spinning wheel and the power tool
directly at you.
• Whenwheelisbindingorwheninterrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless until
the wheel comes to a complete stop. Never
attempt to remove the cut-off wheel from the
cut while the wheel is in motion otherwise
kickback may occur. Investigate and take
corrective action to eliminate the cause of
wheel binding.
• Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may
bind, walk up or kickback if the power tool is
restarted in the workpiece.
• Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under

49
their own weight. Supports must be placed
under the workpiece near the line of cut and
near the edge of the workpiece on both sides
of the wheel.
• Use extra caution when making a “pocket
cut”intoexistingwallsorotherblindareas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can
cause kickback.
5.5 Special safety instructions
• Checkthatthemaximumspeedindicatedon
the grinding disc corresponds to the maxi-
mum speed of the machine. The speed of the

• Whengrindingdiscshavetobemountedon
the thread of the spindle, make sure that the
spindle has sufficient thread. Make sure that
the spindle is sufficiently protected and does
not touch the grinding surface.
• Beforeuse,inspectthegrindingdiscforany
damage. Do not use grinding discs which are
crack-ed, ripped or otherwise damaged.
• Before use, let the machine run idle for 30
seconds. Immediately switch off the machine
in case of abnormal vibrations or occur-
rence of another defect. Carefully inspect the
machine and grinding disc before switching
the machine on again.
• Makesurethatsparksdonotputpeopleinto
danger or that they contact highly flammable
substances.
• Makesurethattheworkpieceissufficiently
supported or clamped. Keep your hands away
from the surface to be cut.
• Alwayswearsafetygogglesandhearingpro-
tection. If desired or required also use another
kind of protection like for example an apron
or helmet.
• Ensure that mounted wheels and points are
fittedinaccordancewiththemanufacturer’s
instructions.
• Ensurethatblottersareusedwhentheyare
provided with the bonded abrasive product
and when they are required.
• Ifaguardissuppliedwiththetoolneveruse
the tool without such a guard.
• 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.
• Ensure that ventilation openings are kept
clear when working in dusty conditions. If it
should become nessesary to clear dust, first
disconnect the tool from the mains supply
(use non metallic objects) and avoid dama-
ging internal parts.
• Though poor conditions of the electrical
mains, shortly voltage drops can appear when
starting the equipment. This can influence
other equipment (eq. blinking of a lamp). If
the mains-impedance Zmax <0.348 Ohm,
such disturbances are not expected. (In case
of need, you may contact your local supply
authority for further information.
5.6 Electrical safety
When using electric machines always obser-
ve the safety regulations applicable in your
country to reduce the risk of fire, electric
shock and personal injury. Read the following

ced.
7. USE
Always follow the safety instructions
and keep to the applicable regula-
tions.
Hold the machine away from the workpiece
when turning it on and off because the grinding
disc could damage the workpiece.
• Clamp the workpiece firmly or use another
method to ensure that it cannot move while
working.
• Check the discs regularly. Worn grinding
discshaveanegativeeffectonthemachine’s
efficiency. Change to a new grinding disc in
good time.
• Always first turn the machine off after use
before removing the plug from the socket.
7.1 Deburring (Fig. 5)
An angle of inclination of 30° to 40° will give
the best results when deburring. Move the
machine back and forth using light pressure.
This will prevent the workpiece from disco-
louring or becoming too hot and will avoid
making groves.
Never use abrasive cutting discs for
deburring work!

52
7.2 Cutting (Fig. 6)
Fig. 6
Maintain firm contact with the workpiece
to prevent vibration and do not tilt or apply
pressure and when cutting. Use moderate pres-
sure when working, appropriate to the material
that is being worked on. Do not slow down
grinding discs by applying sideways counter
pressure. The direction in which you want to
cut is important. The machine must always
work against the direction of the cut; so never
move the machine in the other direction! There
is the risk that the machine will catch in the cut
causing kickback and that you will lose control.
7.3 The ON/OFF/ switch (Fig. 1)
