For Your Safety
Read all safety warnings and all
instructions. Failure to follow the
warnings and instructions may result in
electric shock, fire and/or serious
injury.
❏See data sheet for further safety warnings
and instructions.
Safety warnings that are common
for grinding, sanding, wire brush-
ing or abrasive cutting off opera-
tions
❏This power tool is intended to function as
a grinder, sander, wire brush or cut-off
tool. Read all safety warnings, instruc-
tions, illustrations and specifications pro-
vided with this power tool. Failure to follow
all instructions listed below may result in electric
shock, fire and/or serious injury.
❏This power tool is not recommended for
poslishing. Operations for which the power tool
was not designed may create a hazard and cause
personal injury.
❏Do not use accessories which are not spe-
cifically 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 run-
ning faster than their rated speed can 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 arbor size of wheels, flanges, backing
pads or any other accessory must properly
fit the spindle of the power tool. Accessories
with arbor holes that do not match the mounting
hardware of the power tool will run out of bal-
ance, 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 pads for cracks, tears or excess
wear, wire brushes 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, 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 nor-
mally break apart during this test time.
❏Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses. As
appropriate, wear dust mask, hearing
protectors, gloves and shop apron capa-
ble of stopping small abrasive or work-
piece fragments. The eye protection must be
capable of stopping flying debris generated by
various operations. 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 the work area. Anyone entering the
work area must wear personal protective
equipment. Fragments of workpiece or of a
broken accessory may fly away and cause injury
beyond immediate area of operation.
❏Hold the power tool only by the insulated
gripping surfaces when performing an
operation where the cutting tool may con-
tact hidden wiring or its own power cord.
Contact with a “live” wire will also make exposed
metal parts of the power tool “live” and shock the
operator.
❏Position the cord clear of the spinning
accessory. If you lose control of the power tool,
the cord may be cut or snagged and your hand
or arm may be pulled into the spinning acces-
sory.
❏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 spin-
ning 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.

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 movement 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 condi-
tions and can be avoided by taking proper pre-
cautions 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 handle, if provided, for maxi-
mum 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. The accessory may kickback over
your hand.
❏Do not position your body in the area
where the power tool will move if kickback
occurs. Kickback will propel the tool in the direc-
tion opposite to the wheel’s movement at the
point of snagging.
❏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.
❏Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades
create frequent kickback and loss of control over
the power tool.
Additional safety instructions for
grinding and cutting off opera-
tions
❏Always use guard designed for the type of
wheel you are using. 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 oper-
ator from broken wheel fragments and acciden-
tal contact with wheel.
❏Use only wheel types that are recom-
mended for your power tool and the spe-
cific guard designed for the selected
wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are
unsafe.
❏Wheels must be used only for recom-
mended applications. For example: do not
grind with the side of the cut-off wheel. Abrasive
cut-off wheels are intended for peripheral grind-
ing; 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
selected wheel. Proper wheel flanges support
the wheel thus reducing the possibility of wheel
breakage. Flanges for cut-off wheels may be dif-
ferent from grinding wheel flanges.
❏Do not use worn down wheels from larger
power tools. Wheels intended for larger power
tools are not suitable for the higher speed of a
smaller tool and may burst.
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. Overstress-
ing the wheel increases the loading and suscep-
tibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel break-
age.
❏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.
OBJ_BUCH-413-001.book Page 15 Friday, June 15, 2007 8:03 AM

16–English 1 609 929 L48 • 15.6.07
❏When wheel is binding or when interrupt-
ing 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 work-
piece to minimize the risk of wheel pinch-
ing and kickback. Large workpieces tend to
sag under 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.
Safety warnings specific for sand-
ing operations
❏When sanding, do not use excessively
oversized sanding disc paper. Follow
manufacturers recommendations, when
selecting sanding paper. Larger sanding
paper extending beyond the sanding pad
presents a laceration hazard and may cause
snagging, tearing of the disc, or kickback.
Safety warnings specific for wire
brushing operations
❏Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying
excessive load to the brush. The wire bristles
can easily penetrate light clothing and/or skin.
❏If the use of a guard is recommended for
wire brushing, do not allow any interfer-
ence of the wire wheel or brush with the
guard. Wire wheel or brush may expand in
diameter due to work load and centrifugal
forces.
Additional safety warnings
Wear safety goggles.
❏Use suitable detectors to determine if util-
ity lines are hidden in the work area or
call the local utility company for assist-
ance. Contact with electric lines can lead to fire
and electric shock. Damaging a gas line can lead
to explosion. Penetrating a water line causes
property damage or may cause an electric shock.
❏When working stone, use dust extraction.
The vacuum cleaner must be approved for
the extraction of stone dust. Using this
equipment reduces dust-related hazards.
❏Use a cutting guide when cutting stone.
Without sideward guidance, the cutting disc can
jam and cause kickback.
❏When working with the machine, always
hold it firmly with both hands and provide
for a secure stance. The power tool is guided
more secure with both hands.
❏Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
❏Do not work materials containing asbes-
tos. Asbestos is considered carcinogenic.
❏Take protective measures when dust can
develop during working that is harmful to
one’s health, combustible or explosive.
Example: Some dusts are regarded as carcino-
genic. Wear a dust mask and work with dust/chip
extraction when connectable.
❏Keep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from light
alloys can burn or explode.
❏Never use the machine with a damaged
cable. Do not touch the damaged cable
and pull the mains plug when the cable is
damaged while working. Damaged cables
increase the risk of an electric shock.
❏Use only original Würth accessories.

The vibration emission level given in this information sheet has been measured in accord-
ance with a standardised test given in EN 60745 and may be used to compare one tool
with another.
The vibration emission level will vary because of the ways in which a power tool can be used and may
increase above the level given in this information sheet. This could lead to a significant underestimate of
exposure when the tool is used regularly in such a way.
Note: To be accurate, an estimation of the level of exposure to vibration experienced during a given period
of work should also take into account the times when the tool is switched off and when it is running but not
actually doing the job. This may significantly reduce the exposure level over the total working period.

pull the mains plug.
The machine head
can be rotated with
respect to the
machine housing in
90° steps. In this
manner, the On/Off
switch can be brought
into a more conven-
ient position for spe-
cial working
situations, e.g. for
left-handed persons.
Completely unscrew the four screws. Rotate the
machine head carefully, without removing it
from the housing, to the new position. Screw in
and tighten the four screws again.
Starting Operation
❏Observe correct mains voltage! The volt-
age of the power source must agree with
the voltage specified on the nameplate of
the machine. Power tools marked with
230 V can also be operated with 220 V.
When operating the machine with power from
mobile generators that do not have sufficient reserve
capacity or are not equipped with suitable voltage
control with starting current amplification, loss of
performance or untypical behavior can occur upon

❏Check grinding tools before using. The
grinding tool must be mounted properly
and be able to move freely. Carry out a
test run for at least one minute with no
load. Do not use damaged, out-of-centre
or vibrating grinding tools. Damaged grind-
ing tools can burst and cause injuries.
Kickback stop (EWS 125-S/
EWS 125-ES/ EWS 14-125 S/
EWS 14-150 S)
In case of a sudden drop in speed, e. g. jamming
while carrying out a separating cut, the power supply
to the motor is interrupted.
To restart the operation, switch the On/Off
switch 4to the Off position and start the machine
again.
Restarting protection (EWS 125-S/
EWS 125-ES/ EWS 14-125 S/

The restarting protection feature prevents uncon-
trolled restarting of the machine after an interruption
in the power supply.
To restart the operation, switch the On/Off
switch 4to the Off position and start the machine
again.
Reduced starting current
(EWS 125-S/EWS 125-ES/
EWS 14-125 S/EWS 14-150 S)
The electronic reduced starting current limits the
power consumption when switching the tool on and
enables operation from a 13 ampere fuse.
Constant Electronic Control
(EWS 125-S/EWS 125-ES/
EWS 14-125 S/EWS 14-150 S)
Constant electronic control holds the speed constant
at no-load and under load, and ensures uniform
