 Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris gen-
erated by various operations. The dust mask or respirator
must be capable of filtrating particles generated by your
operation.Prolongedexposuretohighintensitynoisemay
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 accessory may fly away and cause injury beyond
immediate area of operation.
 Hold the power tool by insulated gripping surfaces on-
ly, when performing an operation where the cutting ac-
cessorymaycontacthidden wiring oritsowncord.Cut-
ting accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the op-
erator an electric shock.
 Positionthe cord clearofthespinningaccessory.Ifyou
lose control of the power tool, the cord may be cut or
snagged and your hand or arm may be pulled into the spin-
ning accessory.
 Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may gr-
ab the surface and pull the power tool out of your control.
 Donotrun the power toolwhilecarrying it atyourside.
Accidentalcontactwiththespinningaccessorycouldsnag
your clothing, pulling the accessory into your body.
 Regularlycleanthepowertool’sairvents.Themotor’sfan
will drawthedustinsidethehousingandexcessiveaccumu-
lation of powdered metal may cause electrical hazards.
 Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
 Do not use accessories that require liquid coolants. Us-
ing water or other liquid coolants may result in electrocu-
tion or shock.
Kickback and related warnings
 Kickback is a sudden reaction to a pinched or snagged ro-
tating 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 accesso-
ry’s rotation at the point of the binding.
Forexample,ifanabrasivewheelissnaggedorpinchedby
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 directionof the wheel’smovementatthepointof pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be avoid-
ed by taking proper precautions as given below.
 Maintainafirmgriponthepowertoolandpositionyour
body and arm to allow you to resist kickback forces. Al-
ways use auxiliary 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. Ac-
cessory 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 snagging the accessory. Cor-
ners,sharpedgesorbouncinghaveatendencytosnagthe
rotating accessory and cause loss of control or kickback.
 Do not attach a saw chain woodcarving blade or
toothedsawblade.Suchbladescreatefrequentkickback
and loss of control.
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 se-
lectedwheel. Wheelsforwhichthepowertoolwasnotde-
signed cannot be adequately guarded and are unsafe.
 The grinding surface of the centre depressed wheels
must be mounted below the plane of the guard lip. An
improperlymountedwheelthatprojectsthroughtheplane
of the guard lip cannot be adequately protected.
 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 operator from broken wheel frag-
ments, accidental contact with wheel and sparks that
could ignite clothing.
 Wheels must be used only for recommended applica-
tions. For example: do not grind with the side of the
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 cor-
rect size and shape for your selected wheel. Proper
wheel flanges support the wheel thus reducing the possi-
bilityof wheelbreakage.Flangesforcut-offwheelsmaybe
different 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 pres-
sure.Donotattempttomakeanexcessivedepthofcut.
Overstressing thewheel increases the loading and suscep-
tibility to twisting or bindingofthe wheelin thecut and the
possibility of kickback or wheel breakage.

Bosch Power Tools 2 609 006 763 | (17.1.13)
 Do not position your body in line with and behind the ro-
tating wheel. When the wheel, at the point of operation, is
moving away from your body, the possible kickback may
propelthespinningwheelandthepowertooldirectlyatyou.
 When wheel is binding or when interrupting a cut for
any reason, switch off thepower tool andhold the pow-
er tool motionless until the wheel comes to a complete
stop. Never attempt to remove the cut-off wheel from
thecutwhilethewheelisinmotionotherwisekickback
may occur. Investigate and take corrective action to elimi-
nate the cause of wheel binding.
 Do not restart the cutting operation in the workpiece.
Let the wheel reach full speed and carefully re-enter
the cut. The wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
 Supportpanelsoranyoversizedworkpiecetominimize
the risk of wheel pinching and kickback. Large work-
pieces tend to sag under their own weight. Supports must
beplacedundertheworkpiecenearthelineofcutandnear
the edge of the workpiece on both sides of the wheel.
 Use extra caution when making a “pocket cut” into ex-
isting walls or other blind areas. The protruding wheel
maycutgasorwaterpipes,electricalwiringorobjectsthat
can cause kickback.
Safety warnings specific for sanding operations
 Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when select-
ing sanding paper. Larger sanding paper extending be-
yond 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.
 Iftheuseofaguardisrecommendedforwirebrushing,
do not allow any interference 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 utility lines are
hiddenintheworkareaorcallthelocalutilitycompany
for assistance. Contact with electric lines can lead to fire
and electric shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property damage or
may cause an electric shock.
 Release the On/Off switch and set it to the off position
whenthepower supply is interrupted, e. g.,incase ofa
powerfailure orwhenthe mains plug is pulled. This pre-
vents uncontrolled restarting.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.

EN 60745 and may be usedtocompare one tool withanother.
It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications,withdifferentaccessoriesorpoorlymaintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of thelevelofexposuretovibrationshouldalso
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level overthe total working pe-
riod.

Dust/Chip Extraction
 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
 Observecorrectmains voltage!Thevoltage ofthepow-
er 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 genera-
tors 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 switching on.
Please observe the suitability of the power generator being
used, particularly with regard to the mains voltage and fre-
quency.
Switching On and Off
To start the power tool, push the On/Off switch 3 forwards.
To lock the On/Off switch 3, press the On/Off switch 3 down
at the front until it latches.
To switch off the power tool, release the On/Off switch 3 or,
if it is locked, brieflypush down the back of the On/Off switch
3 and then release it.
To save energy, only switch the power tool on when using it.
 Check grinding tools before using. The grinding tool
must be mounted properly and be able to move freely.
Carryoutatestrunforatleastoneminutewithnoload.
Do not use damaged, out-of-centre or vibrating grind-
ing tools. Damaged grinding tools can burst and cause in-
juries.
Working Advice
 Exercise caution when cutting slots in structural walls;
see Section “Information on Structures”.
 Clamp the workpiece if it does not remain stationary
due to its own weight.
 Do not strain the machine so heavily that it comes to a
standstill.
 After heavily straining the power tool, continue to run
itatno-loadforseveralminutestocooldowntheacces-
sory.
 Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
 Do not use the power tool with a cut-off stand.
Rough Grinding
 Never use a cutting disc for roughing.
The best roughing results are achieved when setting the ma-
chine at an angle of 30° to 40°. Move the machine back and
forth with moderate pressure. In this manner, the workpiece
will not become too hot, does not discolour and no grooves
are formed.
Flap Disc
With the flap disc (accessory), curved surfaces and profiles
can be worked.
Flapdiscshave aconsiderablyhigherservicelife,lowernoise
levels and lower sanding temperatures than conventional
sanding sheets.
Cutting Metal
 For cutting with bonded abrasives, always use the pro-
tection guard for cutting 10.
Whencutting, workwithmoderatefeed, adaptedtothemate-
rial being cut. Do not exert pressure onto the cutting disc, tilt
or oscillate the machine.
Do not reduce the speed of running down cutting discs by ap-
plying sideward pressure.
The machine must al-
ways work in an up-
grinding motion. Other-
wise, the danger exists
of it being pushed un-
controlled out of the
cut.
When cutting profiles
andsquarebar,itisbest
to start at the smallest
cross section.
Cutting Stone
 Provide for sufficient dust extraction when cutting
stone.
 Wear a dust respirator.
 Themachinemaybeusedonlyfordrycutting/grinding.
For cutting stone, it is best to use a diamond cutting disc.
When using the cutting guide with dust extraction protection
guard 17, the vacuum cleaner must be approved for vacuum-
ing masonry dust. Suitable vacuum cleaners are available
from Bosch.

Switch on the machine
and place the front part
of the cutting guide on
theworkpiece.Slide the
machine with moderate
feed, adapted to the ma-
terial to be worked.
For cutting expecially hard material, e. g., concrete with high
pebble content, the diamond cutting disc can overheat and
become damaged as a result. This is clearly indicated by cir-
cular sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and allow the dia-
mond cutting disc to cool by running the machine for a short
time at maximum speed with no load.
Noticeable decreasing work progress and circular sparking
are indications of a diamond cutting disc that has become
dull. Briefly cutting into abrasive material (e. g. lime-sand
brick) can resharpen the disc again.
Information on Structures
SlotsinstructuralwallsaresubjecttotheStandardDIN 1053
Part 1, or country-specific regulations.
These regulations are to be observed under all circumstanc-
es. Before beginning work, consult the responsible structural
engineer, architect or the construction supervisor.
Maintenance and Service
Maintenance and Cleaning
 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and ventilation slots clean.
 In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD). When work-
ing metals, conductive dust can settle in the interior of the
powertool.Thetotalinsulationofthepowertoolcanbeim-

Please store and handle the accessory(-ies) carefully.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
