Safety Notes
General Power Tool Safety Warnings
Read all safety warnings and all in-
structions.Failuretofollowthewarnings
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 orbattery-operated(cordless)
power tool.
Work area safety
f Keepworkareacleanandwelllit.Clutteredordarkareas
invite accidents.
f 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.
f Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
f 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.
f Avoidbodycontactwithearthedorgroundedsurfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is
earthed or grounded.
f Do not expose power tools to rain or wet conditions.
Waterenteringapowertoolwillincreasetheriskofelectric
shock.
f 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.
f When operating a power tool outdoors, use an exten-
sioncord suitablefor outdoor use. Useofa cord suitable
for outdoor use reduces the risk of electric shock.
f 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
f Stay alert, watch what you are doing and use common
sensewhen operating apower tool.Do notuse apower
toolwhileyouaretiredor undertheinfluenceofdrugs,
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
f Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal inju-
ries.
f 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.
f 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.
f Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
f Dress properly. Do not wear loose clothing or jewel-
lery. Keep your hair, clothing and gloves away from
movingparts. Loose clothes, jewellery or long hair can be
caught in moving parts.
f 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
f Donotforcethe powertool.Use thecorrectpower tool
for your application. The correct power tool will do the
job better and safer at the rate for which it was designed.

f 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.
f 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 risk of
starting the power tool accidentally.
f 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.
f Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
condition thatmay affectthe powertool’s operation.If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
f Keepcuttingtoolssharpandclean. Properlymaintained
cuttingtoolswithsharpcuttingedgesarelesslikelytobind
and are easier to control.
f Use the power tool, accessories and tool bits etc. in ac-
cordance 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.
Service
f Haveyourpowertoolservicedbyaqualifiedrepairper-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Safety Warnings for Circular Saws
Cutting procedures
f 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.
f Do not reach underneath the workpiece. The guard can-
not protect you from the blade below the workpiece.
f Adjust the cutting depth to the thickness of the work-
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.
f Neverholdpiecebeingcutinyourhandsoracrossyour
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.
f Hold the power tool by the insulated gripping surfaces
only, when performing an operation where the cutting
toolmay contacthiddenwiring or its owncord. Contact
with a “live” wire will also make exposed metal parts of the
power tool “live” and could give the operator an electric
shock.
f When ripping always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
f 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.
f 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.
f 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.
f Maintain a firm grip with both hands on the saw and po-
sition your arms to resist kickback forces. Position
yourbodytoeithersideoftheblade,butnotinlinewith
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.
f 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.
f Whenrestartingasawintheworkpiece,centrethesaw
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.
f 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.
f Do not use dull or damaged blades. Unsharpened or im-
properlysetbladesproducenarrowkerfcausingexcessive
friction, blade binding and kickback.
f Bladedepthandbeveladjustinglockingleversmustbe
tight and secure before making cut. If blade adjustment
shifts while cutting, it may cause binding and kickback.
f Use extra caution when sawing into existing walls or
other blind areas. The protruding blade may cut objects
that can cause kickback.

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 sure that
guard moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
f 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.
f Assurethatthebaseplateofthesawwillnotshiftwhile
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.

Additional safety warnings
f Donotreachintothesawdustejectorwithyourhands.
They could be injured by rotating parts.
f Do not work overhead with the saw. In this manner you
do not have sufficient control over the power tool.
f Use suitable detectors to determine if utility lines are
hiddenintheworkareaor callthelocalutilitycompany
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.
f Do not operate the power tool stationary. It is not de-
signed for operation with a saw table.
f Donotusehighspeedsteel(HSS)sawblades.Suchsaw
blades can easily break.
f Do not saw ferrous metals. Red hot chips can ignite the
dust extraction.
f 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.
f Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
f 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 92 dB(A); Sound power level
103 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K
determined according to EN 60745:
Cutting wood: ah<2.5 m/s2
, K=1.5 m/s2
,
Cutting metal: ah<2.5 m/s2
, K=1.5 m/s2
.
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given inEN60745 and maybe used to compare one toolwith
another. It may be used for a preliminary assessment of expo-
sure.
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 over the total working pe-
riod.

Dust/Chip Extraction
f Before any work on the machine itself, pull the mains
plug.
f 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.
f Prevent dust accumulation at the workplace. Dusts can
easily ignite.
External Dust Extraction
Mount the vacuum hose 31 (accessory) on to the saw dust
ejector 18.Connect the vacuum hose 31 to a vacuum cleaner
(accessory). An overview for connecting to various vacuum
cleaners can be found at the end of this manual.
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
f Before any work on the machine itself, pull the mains
plug.
Adjusting the Cutting Depth (see figure B–C)
f Adjust the cutting depth to the thickness of the work-
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.

up, the saw retracts to the starting position and the plunging
device is locked again.
To switch off the machine, release the On/Off switch 1.
Note: For safety reasons, the On/Off switch 1 cannot be
locked; it must remain pressed during the entire operation.
Reduced starting current
The electronic reduced starting current limits the power con-
sumption when switching the tool on and enables operation
from a 13 ampere fuse.
Constant Electronic Control
Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perform-
ance.
Speed preselection
The required speed can be preselected with the thumbwheel
24 (also while running).
Therequiredspeeddependsonthesawbladebeingusedand
on the material being worked (see overview of saw blades at
the end of these operating instructions).
Working Advice
Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in the cutting di-
rection.Excessivefeedsignificantlyreducestheservicelifeof
the saw blade and can cause damage to the power tool.
Sawing performance and cutting quality depend essentially
on the condition and the tooth form of the saw blade. There-
fore,useonlysharpsawbladesthataresuitedforthematerial
to be 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 cutting spruce lengthways, long spiral chips are
formed.
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 18. 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.Thisensuresacleancutandpreventsbladebind-
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.
Sawing Light Building Materials (Materials with Mineral
Content)
f When sawing light building materials,observethe stat-
utory provisions and the recommendations of the ma-

Light building materials may only be sawn dry and when ap-
plying dust extraction. Always work with the guide rail 29 (ac-
cessory).
The vacuum cleaner must be approved for the extraction of
masonry dust. Bosch provides suitable vacuum cleaners.
Sawing with Guide Rail (see figure D)
The guide rail 29 is used to carry out straight cuts.
The rubber lip on the guide rail acts as a splinter guard; it pre-
vents fraying of the surface while sawing wooden materials.
For this, the teeth of the saw blade must face directly against
the rubber lip.
Prior to the very first cut, the rubber lip must be adapted with
theguiderail29tothecircularsawbeingused.Forthis,place
the guide rail 29 over its complete length on a workpiece. Ad-

ro degree angle. Switch the circular saw on and guide it uni-
formly and with light feed in the cutting direction.
Two guide rails can be connected to one with use of the con-

Adapting the Base Plate to other Guide Rails
(see figure E)
The small groove integrated in base plate 7 can be used for
the guide rails shown on the accessories page. To adapt the
base plate to guide rails of other manufacturers with a wider
guide fin, remove plastic insert 34. Place the saw onto the
guide rail and adjust its accurate fit with the two knurled
screws 35, if required.
Sawing with Parallel Guide (see figure F–G)
The parallel guide 14 enables exact cuts along a workpiece
edge and cutting strips of the same dimension.
