Safety Instructions
General Power Tool Safety Warnings
WARNING
Read all safety warnings, instructions, illustrations and specifica-
tions provided with this power tool. Failure to follow all instructions
listed below may result in electric shock, fire and/ or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded)
power tool or battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Power tools create sparks which may
ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
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.
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.
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.
Personal safety
Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-tion while operating
power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective
equipment such as a dust mask, non-skid safety shoes, hard hat or hearing
protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to power source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the switch or energising
power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part of the power tool may result in
personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair and
clothing away from moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust
collection can reduce dust-related hazards.
Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause
severe injury within a fraction of a second.
Power tool use and care
Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which
it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power
tool that cannot be controlled with the switch is dangerous and must be
repaired.
Disconnect the plug from the power source and/or remove the battery pack, if
detachable, from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power
tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools and accessories. Check for misalignment or binding of
moving parts, breakage of parts and any other condition that may affect the
power tool’s operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended
could result in a hazardous situation.
Keep handles and grasping surfaces dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
Service
u Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
Safety information for the angle grinder
Safety warnings common for grinding, sanding, wire brushing or cutting-off
operations:
This power tool is intended to function as a grinder, sander, wire brush or
cut-off tool. Read all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure to follow all
instructions listed below may result in electric hock, fire and/or serious
injury.
Operations such as polishing or hole cutting are not to be performed with this
power tool. Operations for which the power tool was not designed may create a
hazard and cause personal injury.
Do not convert this power tool to operate in a way which is not specifically
designed and specified by the tool manufacturer. Such a conversion may result
in a loss of control and cause serious personal injury.
Do not use accessories which are not specifically designed and specified 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 dimensions of the accessory mounting must fit the dimensions of the
mounting hardware of the power tool. 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.
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 in-stall an undamaged accessory. After
inspecting and installing an accessory, position 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 appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stopping small abrasive or
workpiece fragments. The
eye protection must be capable of stopping flying debris generated by various
applications. The dust mask or respirator must be capable of filtrating
particles generated by the particular application. 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 accessory may fly away and cause injury beyond immediate area of
operation.
Hold the power tool by insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden 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.
Position the cord clear of the spinning accessory. 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 powdered metal may cause
electrical hazards.
Do not operate the power tool near flammable 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 conditions and can be avoided by taking
proper precautions as given below.
Maintain a firm grip with both hands on the power tool and position your body
and arms 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 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
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, segmented diamond wheel with a
peripheral gap greater than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
Safety warnings specific for grinding and cutting-off operations:
Use only wheel types that are specified for your power tool and the specific
guard designed for the selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
The grinding surface of centre depressed wheels must be mounted below the
plane of the guard lip. An improperly mounted wheel that projects through the
plane 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 the operator from broken wheel fragments,
accidental contact with wheel and sparks that could ignite clothing.
Wheels must be used only for specified 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
selected 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. A wheel intended for
larger power tool is not suitable for the higher speed of a smaller tool and
may burst.
When using dual purpose wheels always use the correct guard for the
application being performed. Failure to use the correct guard may not provide
the desired level of guarding, which could lead to serious injury.
Additional safety warnings specific for 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 susceptibility to twisting or binding of the wheel in the cut and
the possibility of kickback or wheel breakage.
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 the wheel is binding or when interrupting a cut for any reason, switch
off the power tool and hold it 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 re-enter 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 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.
Do not attempt to do curved cutting. 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 breakage, which can lead to serious
injury.
Safety warnings specific for sanding operations:
Use proper sized sanding disc paper. Follow manufacturers recommendations,
when selecting sanding paper. Larger sanding paper extending too far 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 specified for wire brushing, 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 information
Wear safety goggles.
The protective guard must not be used for cutting. With a suitable adapter,
the protective guard can also be used for cutting.
Hold the power tool firmly with both hands and make sure you have a stable
footing. The power tool can be more securely guided with both hands.
For application tools with an internal thread, such as brushes, attention must
be paid to the max. thread length of the grinding spindle. The spindle end
must not touch the base of the application tool.
Use suitable detectors to determine if utility lines are hidden in the work
area or call the local utility company for assistance. 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.
Do not touch grinding and cutting discs until they have cooled down. The discs
can become very hot while working.
Release the On/Off switch and set it to the off position when the power supply
is interrupted, e. g., in case of a power failure or when the mains plug is
pulled. This prevents uncontrolled restarting.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice
is held more secure than by hand.
Store the application tools inside buildings, in a dry, frost-free room at a
uniform temperature.
Remove the application tools before transporting the power tool. This will
allow you to avoid damage.
Bonded cutting and grinding discs have an expiration date, after which the
discs must no longer be used. Products sold in GB only: Your product is fitted
with an BS 1363/A approved electric plug with internal fuse (ASTA approved to
BS 1362). If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an authorised customer
service agent. The replacement plug should have the same fuse rating as the
original plug. The severed plug must be disposed of to avoid a possible shock
hazard and should never be inserted into a mains socket elsewhere.

A) Rated no-load speed for the selection of appropriate application tools in
accordance with EN IEC 62841-2-3. The actual speed is lower for safety reasons
and according to production tolerances.
The specifications apply to a rated voltage [U] of 230 V. These specifications
may vary at different voltages and in country-specific models.
Noise/Vibration Information
Noise emission values determined according to EN IEC 62841-2-3.
Typically the A-weighted noise level of the power tool are: 93 dB(A); sound
power level 101 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined
according to EN IEC 62841-2-3:
Surface grinding (roughing) and cut-off grinding: ah = 4.3 m/s 2 , K = 1.5
m/s 2 .
Grinding thin metal sheets or other materials that tend to easily vibrate with
a large surface area can cause the noise emission value to increase by up to
15 dB. Suitable, heavy damping mats can reduce the increased noise emissions.
Increased noise emissions must be taken into consideration, both for the risk
assessment of the noise output and for selecting suitable hearing protection.
The vibration level and noise emission value given in these instructions have
been measured in accordance with a standardised measuring procedure and may be
used to compare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent the main
applications of the power tool. However, if the power tool is used for other
applications, with different application tools or is poorly maintained, the
vibration level and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total working period.
To estimate vibration and noise emissions accurately, the times when the tool
is switched off or when it is running but not actually being used should also
be taken into account.
This may significantly reduce vibration and noise emissions over the total
working period.
Implement additional safety measures to protect the operator from the effects
of vibration, such as servicing the power tool and application tools, keeping
their hands warm, and organising workflows correctly.
Restart protection
The restart protection feature prevents the power tool from uncontrolled
starting after the power supply to it has been interrupted.
To restart the tool, set the on/off switch (3) to the off position and then
switch the power tool on again.
Fitting
Fitting Protective Equipment
Pull the plug out of the socket before carrying out any work on the
power tool.
Note: If the grinding disc breaks during operation or the holding
fixtures on the protective guard/power tool become damaged, the power tool
must be sent to the after-sales service immediately; see the “After-Sales
Service and Application Service” section for addresses.
Protective guard for grinding
Note: Remove the fitted cover for cutting (7) before using the power tool
for grinding (see figure B). Place the protective guard (6) onto the holder on
the power tool until the coding cams of the protective guard are aligned with
the holder. When doing so, press and hold the unlocking lever (1).
Press the protective guard (6) onto the spindle collar until the shoulder of
the protective guard is sitting on the flange of the power tool and rotate the
protective guard until it audibly clicks into place.
Adjust the position of the protective guard (6) to meet the requirements of
the operation. To do this, push the unlocking lever (1) upwards and rotate the
protective guard (6) into the required position.
Always position the protective guard (6) such that the two cams on the
unlocking lever (1) engage in the corresponding openings on the protective
guard (6).
Adjust the protective guard (6) such that sparking in the direction of the
operator is prevented.
The protective guard (6) must only be adjustable while the unlocking lever (1)
is actuated. Otherwise, the power tool must not be used any more under any
circumstances and must be sent to the after-sales service.
Note: The coding cams on the protective guard (6) ensure that only a
protective guard that is suitable for the power tool can be fitted.
Protective guard for cutting
For cutting, always use the protective guard for cutting (5) or the protective
guard for grinding (6) together with the cover for cutting (7).
Provide sufficient dust extraction when cutting stone. The protective guard
for cutting (5) is fitted in the same way as the protective guard for grinding
(6).
Plastic cover for cutting
Attach the plastic cover for cutting (7) to the protective guard for grinding
(6) (see figure A). The cover (7) audibly and visually engages on the
protective guard (6).
To remove the cover (see figure B), unlock the cover (7) on the left- or
right-hand side of the protective guard (6) (➊) and remove the cover (➋).
Extraction guard for cutting with a guide block
The extraction guard for cutting with a cutting guide (21) is fitted in the
same way as the protective guard for grinding.
By securing the auxiliary handle (4) with the clip through the extraction
guard on the gearbox housing, the power tool is firmly attached to the
extraction guard. A suitable Bosch dust extractor can be connected to the
extraction guard with a cutting guide (21). To do so, insert the vacuum hose
with dust extraction adapter into the provided receiving connection of the
extraction guard.
Note: The friction generated by the dust in the vacuum hose and accessory
during extraction causes an electrostatic charge that the user may experience
as static discharge (depending on environmental factors and their
physiological state). Bosch generally recommends using an anti-static vacuum
hose (accessory) to vacuum up fine dust and dry materials.
Hand guard
Always fit the hand guard (16) when working with the rubber sanding pad (17)
or the cup brush (20). Attach the hand guard (16) to the auxiliary handle (4).
Standard auxiliary handle
Screw the auxiliary handle (4) on the right or left of the machine head
depending on the working method.
u Do not operate your power tool without the auxiliary handle (4).
u Do not continue to use the power tool if the auxiliary handle (4)/ is
damaged. Do not make any alterations to the auxiliary handle (4)/.
Fitting the Abrasive Tools
Pull the plug out of the socket before carrying out any work on the power
tool.
Do not touch grinding and cutting discs until they have cooled down. The discs
can become very hot while working. Clean the grinding spindle (15) and all the
parts to be fitted. Lock the grinding spindle with the spindle lock button (2)
before clamping and releasing the abrasive tools.
Do not press the spindle lock button while the grinding spindle is moving.
The power tool may become damaged if you do this.
Grinding/Cutting Disc
Pay attention to the dimensions of the grinding tools. The mounting hole
diameter must fit the mounting flange without play. Do not use reducers or
adapters.
When using diamond cutting discs, pay attention that the direction-of-rotation
arrow on the diamond cutting disc and the direction of rotation of the machine
(see direction-of-rotation arrow on the machine head) agree.
See graphics page for the mounting sequence. To fasten the grinding/cutting
disc, screw on the clamping nut (12) and tighten with the two-hole spanner.
After fitting the abrasive tool, check that the abrasive tool is fitted
correctly and can turn freely before switching on the power tool. Make sure
that the abrasive tool does not brush against the protective guard or other
parts.
Approved abrasive tools
You can use all the abrasive tools mentioned in these operating instructions.
The permissible speed [min -1 ] or the circumferential speed [m/s] of the
abrasive tools used must at least match the values given in the table.
It is therefore important to observe the permissible
rotational/circumferential speed on the label of the abrasive tool.

Dust/Chip Extraction
The dust from materials such as lead paint, some types of wood, minerals and
metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reactions and/or cause
respiratory illnesses in the user or in people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as carcinogenic,
especially in conjunction with wood treatment additives (chromate, wood
preservative). Materials containing asbestos may only be machined by
specialists.
–Use a dust extraction system that is suitable for the material wherever
possible.
–Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in the country of
use must be observed.
Avoid dust accumulation at the workplace. Dust can easily ignite.
Operation
Do not load the power tool so heavily that it comes to a stop.
Pull the plug out of the socket before carrying out any work on the
power tool.
Exercise caution when cutting slots in structural walls; see the
“Information on structural design” section.
Clamp the workpiece if it is not secure under its own weight.
If the power tool has been subjected to a heavy load, continue to run it
at no-load for several minutes to cool down the accessory.
Do not use the power tool with a cut-off stand.
**** Do not touch grinding and cutting discs until they have cooled down. The
discs can become very hot while working.
Working Advice
Rough grinding
Always use the protective guard for grinding (6) when rough grinding
with bonded abrasives.
Never use cutting discs for rough grinding.
When rough grinding, the protective guard for cutting (5) or the
protective guard for grinding (6) with a fitted cover for cutting (7) can
impact the workpiece and lead to a loss of control.
The best rough grinding results are achieved with a set angle of 30° to 40°.
Move the power tool back and forth with moderate pressure. This will ensure
that the workpiece does not become too hot or discolour and that grooves are
not formed.
The protective guard for cutting (5) or the protective guard for
grinding (6) with a fitted cover for cutting (7) must be used when using
bonded discs which are approved for cutting and grinding.
Surface grinding with flap disc
** Always use the protective guard for grinding (6) when grinding with the
flap disc.
The flap disc (accessory) enables you to machine curved surfaces and profiles.
Flap discs have a considerably longer service life, lower noise levels and
lower grinding temperatures than conventional grinding discs.
Surface grinding with sanding disc
** Always fit the hand guard (16) when working with the rubber sanding pad
(17).
Grinding with a sanding disc can be done without a protective guard.
See the graphics page for fitting instructions.
Screw on the round nut (19) and tighten it with the two-pin spanner.
Cup brush
Brushing with cup brushes can be performed without the protective guard.
Always fit the hand guard (16) when working with the cup brush.
See the graphics page for fitting instructions.
The cup brush with M14 thread must be screwed onto the grinding spindle until
it rests firmly against the grinding spindle flange at the end of the grinding
spindle thread. Tighten the cup brush with an open-ended spanner.
Cutting Metal
For cutting metal with bonded cutting discs or diamond cutting discs,
always use the protective guard for cutting (5) or the protective guard for
grinding (6) with a fitted cover furcating (7).
When using the protective guard for grinding (6) for cutting work with
bonded cutting discs, there is an increased risk of being exposed to sparks,
particles and disc fragments if the disc breaks.
When carrying out abrasive cutting, use a moderate feed that is suited to the
material being machined. Do not exert pressure on the cutting disc and do not
tilt or swing the power tool.
Do not attempt to reduce the speed of a cutting disc coming to a stop by
applying pressure from the side.
The power tool must always work in an up-grinding motion. Otherwise there is a
risk that it will be pushed uncontrolled out of the cut.
For best results when cutting profiles and rectangular tubing, start at the
smallest cross section.
Cutting stone
For cutting stone with bonded cutting discs or diamond cutting discs for
concrete/stone, always use the
extraction guard for cutting with a cutting guide (21) or the protective guard
for cutting (5) or the protective guard for grinding (6) with a fitted cover
for cutting (7).
Provide sufficient dust extraction when cutting stone.
Wear a dust mask.
The power tool may be used only for dry cutting/grinding.
When using the protective guard for cutting (5) , the protective guard for
grinding (6) or the protective guard for grinding (6) with a fitted cover for
cutting (7) for cutting and grinding applications in concrete or masonry,
there is an increased dust load and an increased risk of losing control of the
power tool, which can lead to kickback.
For cutting stone, it is best to use a diamond cutting disc.
When using the extraction guard for cutting with a cutting guide (21), the
dust extractor must be approved for extracting stone dust. Suitable dust
extractors are available from Bosch.
Switch on the power tool and position it with the front part of the cutting
guide on the workpiece. Move the power tool with a moderate feed motion that
is suited to the material being machined.
When cutting especially hard materials such as concrete with a high pebble
content, the diamond cutting disc can overheat and become damaged as a result.
This is clearly indicated by circular sparking, rotating with the diamond
cutting disc.
If this happens, stop cutting and allow the diamond cutting disc to cool down
by running the power tool for a short time at maximum speed with no load.
If work is noticeably slower and with circular sparking, this indicates that
the diamond cutting disc has become blunt.
You can resharpen the disc by briefly cutting into abrasive material (e.g.
lime-sand brick). Information on structural design Recesses in load-bearing
walls are subject to country-specific regulations. These regulations must be
observed under all circumstances. Seek advice from the responsible structural
engineer, architect or construction supervisor before starting work.
Start-Up
Pay attention to the mains voltage. The voltage of the power source must match
the voltage specified on the rating plate of the power tool. Power tools
marked with 230 V can also be operated with 220 V.
Products that are only sold in AUS and NZ: Use a residual current device (RCD)
with a nominal residual current of 30 mA or less.
When operating the power tool using a mobile generator that does not have
sufficient reserve capacity or an adequate voltage control system with inrush
current boost converter, loss of performance or atypical behaviour may occur
upon switch-on.
Please check the suitability of the power generator you are using,
particularly with regard to the mains voltage and frequency.
Switching on/off
To start the power tool, push the on/off switch (3) forward.
To lock the on/off switch (3) in position, push the on/off switch (3)
forward and down until it clicks into place.
To switch off the power tool, release the on/off switch (3); or, if the switch
is locked, briefly push the on/off switch (3) backward and down and then
release it.
Always check abrasive tools before using them. The abrasive tool must be
fitted properly and be able to move freely. Carry out a test run for at least
one minute with no load. Do not use abrasive tools that are damaged, run
untrue or vibrate during use. imaged abrasive tools can burst apart and cause
injuries.
Maintenance and Service
Maintenance and Cleaning
Pull the plug out of the socket before carrying out any work on the power
tool.
To ensure safe and efficient operation, always keep the power tool and the
ventilation slots clean.
In order to avoid safety hazards, if the power supply cord needs to be
replaced, this must be done by Bosch or by an after-sales service centre that
is authorised to repair Bosch power tools.
Store and handle the accessories carefully.
