Safety Notes
General Power Tool Safety Warnings
Read all safety warnings and all in-
structions.Failure tofollow thewarnings
and instructions may result in electric shock, fire and/or seri-
ous injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
power tool.
Work area safety
Keepworkarea cleanandwelllit. Clutteredordark 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.
Avoidbodycontactwithearthedorgroundedsurfaces,
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.
Waterenteringa powertoolwillincrease theriskof 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 and moving parts. Damaged
or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an exten-
sion 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 unavoid-
able, 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
toolwhile you are tiredor underthe influence ofdrugs,
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, orhearing protectionused
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 en-
ergising power tools that have the switch on invites acci-
dents.
Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a ro-
tating 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 jewel-
lery. Keep your hair, clothing and gloves 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 ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
Power tool use and care
Donot force the powertool. Use the correctpower 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 the
battery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the riskof
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. Check for misalignment or bind-
ing 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.

Safety Warnings for Circular Saws
Cutting procedures
DANGER: Keep hands away from cutting area and the
blade. Keep your second hand on auxiliary handle, or
motor housing. If both hands are holding the saw, they
cannot be cut by the blade.
Do not reach underneath the workpiece. The guard can-
not protect you from the blade below the workpiece.
Adjust the cutting depth to the thickness of the work-
piece. Less than a full tooth ofthe blade teeth should be
visible below the workpiece.
Never hold piece being cut in your hands or across your
leg. Secure the workpiece to a stable platform. It is im-
portant to support the work properly to minimize body ex-
posure, blade binding, or loss of control.
Hold the power tool by the insulated gripping surfaces
only, when performing an operation where the cutting
tool may contact hidden wiring or its own cord.Contact
with a “live” wire will also make exposed metal parts of the
power tool “live” and could give the operator an electric
shock.
When ripping always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
Always use blades with correct size and shape (dia-
mond versus round) of arbour holes. Blades that do not
match the mounting hardware of the saw will run eccentri-
cally, causing loss of control.
Never use damaged or incorrect blade washers or bolt.
The blade washers and bolt were specially designed for
your saw, for optimum performance and safety of opera-
tion.
Kickback causes and related warnings
– Kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator;
– When the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
– If the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the
kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect oper-
ating procedures or conditions and can be avoided by tak-
ing proper precautions as given below.
Maintain a firm grip with both hands on the saw and po-
sition your arms to resist kickback forces. Position
yourbodyto eithersideoftheblade,but notinlinewith
the blade. Kickback could cause the saw to jump back-
wards, but kickback forces can be controlled by the opera-
tor, if proper precautions are taken.
When blade is binding, or when interrupting a cut for
any reason, release the trigger and hold the saw mo-
tionless in the material until the blade comes to a com-
plete stop. Never attempt to remove the saw from the
work or pull the saw backward while the blade is in mo-
tion or kickback may occur. Investigate and take correc-
tive actions to eliminate the cause of blade binding.
Whenrestartinga sawin theworkpiece,centre thesaw
blade in the kerf and check that saw teeth are not en-
gaged into the material. If saw blade is binding, it may
walk up or kickback from the workpiece as the saw is re-
started.
Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag under
their own weight. Supports must be placed under the pan-
el on both sides, near the line of cut and near the edge of
the panel.
Do not use dull or damaged blades. Unsharpened or im-
properlysetblades producenarrow kerfcausingexcessive
friction, blade binding and kickback.
Bladedepth and beveladjusting locking leversmust be
tight and secure before making cut. If blade adjustment
shifts while cutting, it may cause binding and kickback.
Use extra caution when sawing into existing walls or
other blind areas. The protruding blade may cut objects
that can cause kickback.
Guard function
Checkguard for properclosing beforeeach use.Do not
operate the saw if guard does not move freely and en-
close the blade instantly. Never clamp or tie the guard
so that the blade is exposed. If saw is accidentally
dropped, guard may be bent. Check to make surethat
guard moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
Check the operation and condition of the guard return
spring. If the guard and the spring are not operating
properly, they must be serviced before use. Guard may
operate sluggishly due to damaged parts,gummy depos-
its, or a build-up of debris.
Assurethatthe baseplate ofthesaw willnotshift while
performing the “plunge cut” when the blade bevel set-
ting is not at 90°. Blade shifting sideways will cause bind-
ing and likely kick back.
Alwaysobserve that the guardis covering theblade be-
fore placing saw down on bench or floor. An unprotect-
ed, coasting blade will cause the saw to walk backwards,
cutting whatever isin its path. Be aware of the time it takes
for the blade to stop after switch is released.

Cut-off machine safety warnings
The guard provided with the tool must be securely at-
tached to the power tool and positioned for maximum
safety, so the least amount of wheel is exposed to-
wards the operator. Position yourself and bystanders
away from the plane of the rotating wheel. The guard
helps to protect operator from broken wheel fragments
and accidental contact with wheel.
Use only diamond cut-off wheels for your power tool.
Just because an accessory can be attached to your power
tool, it does not assure safe operation.
Therated speedof the accessorymust beat least equal
to the maximum speed marked on the power tool. Ac-
cessories running faster than their rated speed can break
and fly apart.
Wheels must be used only for recommended applica-
tions. For example: donot grind with the side of cut-off
wheel.Abrasivecut-offwheelsare intended forperipheral
grinding, side forces applied to these wheels may cause
them to shatter.
Always use undamaged wheel flanges that are of cor-
rect diameter for your selected wheel. Proper wheel
flanges support the wheel thus reducing the possibility of
wheel breakage.
The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power
tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
The arbour size of wheels and flanges must properly fit
thespindleof the powertool. Wheels and flanges withar-
bour holesthatdo notmatch themountinghardware ofthe
power tool will run out of balance, vibrate excessively and
may cause loss of control.
Do not use damaged wheels. Before each use, inspect
the wheels for chips and cracks. If power tool or wheel
is dropped, inspect for damage or install an undam-
aged wheel. After inspecting and installing the wheel,
position yourself and bystanders away from the plane
of the rotating wheel and run the power tool at maxi-
mumno loadspeed foroneminute. Damagedwheelswill
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 pro-
tectors, gloves and shop apron capable of stopping
small abrasive or workpiece fragments. The eye protec-
tion must be capable of stopping flying debris generated
byvariousoperations. Thedustmaskor respiratormustbe
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 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
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make ex-
posed metal parts of the power tool “live” and could give
the operator an electric shock.
Position the cord clear of the spinningaccessory. If you
lose control, thecord maybe cutorsnaggedand yourhand
or arm may be pulled into the spinning wheel.
Never lay the power tool down until the accessory has
come to a complete stop. The spinning wheel may grab
the surface and pull the power tool out of your control.
Do not run the power tool while carrying it at yourside.
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
fanwill drawthe dustinsidethe housingand excessiveaccu-
mulation 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. Pinching or snagging causes rapid stalling of
the rotating wheel which in turn causes the uncontrolled
power tool to be forced in the direction opposite of the
wheel’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 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.
Maintaina firmgripon thepowertoolandpositionyour
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 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
propelthe spinningwheel andthepower tooldirectly atyou.
Use special care when working corners, sharp edges,
etc. Avoid bouncing and snagging the accessory. Cor-
ners,sharp edges orbouncing have a tendency to snag the
rotating accessory and cause loss of control or kickback.
Do not attach a saw chain, woodcarving blade, seg-
mented diamond wheel with a peripheral gap greater

than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
Do not “jam” the cut-off wheel or apply excessive pres-
sure.Donotattempt tomakeanexcessivedepthofcut.
Overstressing the wheel increases the loading and suscep-
tibility to twisting or binding ofthe wheel in the cut and the
possibility of kickback or wheel breakage.
When wheel is binding or when interrupting a cut for
any reason, switch off the power tool and hold the pow-
er tool motionless until the wheel comes to a complete
stop. Never attempt to remove the cut-off wheel from
thecut whilethe wheel isin motionotherwise kickback
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.
Supportpanelsor anyoversizedworkpieceto minimize
the risk of wheel pinching and kickback. Large work-
pieces tend to sag under their own weight. Supports must
beplaced undertheworkpiecenear thelineof cutandnear
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
maycut gasor waterpipes,electricalwiringor objectsthat
can cause kickback.
Wear safety goggles.
Use clamps or another practical way to secure and sup-
port the workpiece to a stable platform. Holding the
work by your hand or against the body leaves it unstable
and may lead to loss of control.
Wear hearing protection, safety goggles, dust mask
and gloves. As dust mask, use at least a particle filter-
ing half mask of filter class FFP 2.
Additional safety warnings
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.
When working with the machine, always hold it firmly
with both hands and provide for asecure stance. The
power tool is guided more secure with both hands.
Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
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 in-
crease the risk of an electric shock.
Do not reach into the saw dustejector with your hands.
They could be injured by rotating parts.
Do not work overhead with the power tool. Sufficient
control of the power tool is not ensured in this working
manner.
Use suitable detectors to determine if utility lines are
hiddenin the workarea orcall thelocalutility company
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.
Do not operate the power tool stationary. It is not de-
signed for operation with a saw table.
Donot usehighspeedsteel (HSS)saw blades.Such saw
blades can easily break.
Do not saw ferrous metals. Red hot chips can ignite the
dust extraction.
Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.

Technical Data
Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 97 dB(A); Sound power level
108 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values ah(triax vector sum) and uncertainty K
determined according to EN 60745:
Sawing wood: ah<2.5 m/s2, K=1.5 m/s2,
Sawing metal: ah<2.5 m/s2, K=1.5 m/s2,
Cutting tiles: ah=2.5 m/s2, K=1.5 m/s2.
The vibration level given in this information sheet has been
measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth-
er. 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,with differentaccessoriesor insertiontools oris
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This maysig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
fromtheeffectsof vibrationsuchas:maintain thetool andthe
accessories, keep the hands warm, organisation of work pat-
terns.

Dust/Chip Extraction
Before any work on the machine itself, pull the mains
plug.
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.
– Use a dust extraction system suitable for the material
being worked.
– 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.

cleaner (accessory). An overview for the connection of vari-
ous vacuum cleaners can be found at the end of these instruc-
tions.
The machine can be plugged directly into the receptacle of a
Bosch all-purpose vacuum cleaner with remote starting con-
trol. The vacuum cleaner starts automatically when the ma-
chine is switched on.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Operation
Operating Modes
Before any work on the machine itself, pull the mains
plug.
Adjusting the Cutting Depth (see figure B)
Adjust the cutting depth to the thickness of the work-
piece. Less than a full tooth ofthe blade teeth should be
visible below the workpiece.
Loosen the screw for depth-of-cut adjustment 8by turning in
rotation direction .
Using slider 5, adjust the desired cutting depth (material
thickness + tooth height of the application tool) atthe cutting-
depth scale ().
Tighten the screw for depth-of-cut adjustment 8by turning in
rotation direction .
Starting Operation
Observe correct mains voltage! The voltage of the pow-
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.
Switching On and Off
To start the power tool, firstly actuate the lock-off button 1
toward the front and afterwards, press and hold the On/Off
switch 2(see figure C).
Actuatinglock-offbutton1releasestheplunging device atthe
same time, and allows for the power tool tobe pushed down.
This makes the application tool plunge into the workpiece.
When pulling up, the power tool retractsback to the starting
position and the plunging device is locked again.
To switch off the machine, release the On/Off switch 2.
Note: For safety reasons, the On/Off switch 2cannot be
locked; it mustremain pressed during the entire operation.
To save energy, only switch the power tool on when using it.
Working Advice
Protect application tools against impact and shock.
Guide the power tool uniformly and with light feed in the cut-
tingdirection. Donot pullthe machine toward the rear! Exces-
sive feed considerably reduces the service life of the applica-
tion tools and can damage the power tool.
The cutting capacity and the cutting quality primarily depend
on the condition and the tooth form of the application tool.
Therefore, only use sharp application tools suitable for the
material being worked.
Sawing Wood
The correct selection of the saw blade depends on the type
and quality of the wood and whether lengthway or crossway
cuts are required.
When performing lengthway cuts in spruce, long, spiral-
shaped chips/shavings develop. These can clog the sawdust
ejector 20.
Beech and oak dusts are especially detrimental to health.
Therefore, work only with dust extraction.
Sawing Plastic
Note: When sawing plastic, especially PVC, long spiral-
shaped shavings develop, which can be electrostatically
charged. These can clog the sawdust ejector 20. It is recom-
mended to work with dust extraction.
Guide the switched on power tool against the workpiece and
carefully start the cut. Continue the cut with low feed and
without interruption, so that the saw teeth do not gum up too
quickly.
Sawing Non-ferrous Metals
Note: Use only a sharp saw blade that is suitable for non-fer-
rousmetals. Thisensures aclean cutand preventsblade bind-
ing.
Guide the switched on power tool against the workpiece and
carefully start the cut. Continue the cut with low feed and
without interruption.
When sawing profiles, always begin the cut from the narrow
side; when sawing U-profiles, never start the cut from the
open side. Support long profiles in order to avoid blade bind-
ing and kickback of the power tool.
Cutting Tiles
Whencutting tiles,observethestatutory provisionsand
the recommendations of the material manufacturers.
The diamond cutting disc must be approved for cutting tiles.
Suitable diamond cutting discs are available from Bosch.
Diamond cutting discs become very hot during opera-
tion; do not touch them until they have cooled down.
The power tool can become very hot in the area of the dia-
mond cutting disc. Therefore, allow it to cool down between
two cuts.
Tiles may only be cut dry and only using dust extraction.
The vacuum cleaner must be approved for the extraction of
masonry dust. Bosch provides suitable vacuum cleaners.
Working with an Auxiliary Stop (see figure E)
For sawing large workpieces or straight edges,a board or lath
can be fastened to the workpiece as an auxiliary stop, and the
power tool can be guided by its base plate alongside the aux-
iliary stop.

Cutting Marks (see figure E)
The “CutControl” viewing window 7, which folds out to the
front, is used for precise guiding of the power tool alongside
the cutting line on the workpiece.
The cutting mark 19 indicates the position of the application
tool for right-angled cuts.
For a dimensionally accurate cut, position the power tool
against the workpiece as shown in the figure. It is recom-
mended to carry out a test cut.
Plunge Cuts (see figure D)
The marks on the base plate indicate the cutting edge on the
workpiece at maximum cutting depth.
– Place the base plate 3 on the working surface. Make sure
that the rear mark on base plate 3 corresponds with the
beginning of the cutting line.
– Switch the power tool on and wait until the saw blade 14
has reached its operating speed.
– Plunge the saw blade 14 slowly into the workpiece. Plung-
ing in too quickly can lead to kickback. Guide the machine
alongside the cutting line. Do not pull the machine toward
the rear!
– When reaching the end of the cutting line, lift the power
tool from the workpiece, and leave it switched on for a few
seconds.
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.
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.
The blade guard 6must always move freely and retract auto-
matically. Therefore, always keep the area around the blade
guard6clean. Remove dust and chips/shavings using a brush
or by blowing out with compressed air.
Saw blades that are not coated can be protected against cor-
rosion with a thin coat of acid-free oil. Before use, the oil must
be removed again, otherwise the wood will become soiled.
Resin and glue residue on the saw blade produces poor cuts.
Therefore, clean the saw blade immediately after use.
