Working safely with this ma-
chine is possible only when the
operating and safety information
are read completely and the in-
structions contained therein are
strictly followed. In addition, the
general safety notes in the enclosed booklet
must be observed. Before using for the first
time, ask for a practical demonstration.
■ Wear protective glasses and hearing protec-
tion.
■ Wear additional protection equipment for your
safety, such as protective gloves, sturdy
shoes, hard hat and apron.
■ The dust that is produced while working can be
detrimental to health, inflammable or explo-
sive. Suitable safety measures are required.
Examples: Some dusts are regarded as carci-
nogenic. Use suitable dust/chip extraction and
wear a dust protection mask.
■ Dust from light alloys can burn or explode. Al-
ways keep the workplace clean, as blends of
materials are particularly dangerous.
■ If the mains cable is damaged or cut through
while working, do not touch the cable but im-
mediately pull the mains plug. Never use the
machine with a damaged cable.
■ Connect machines that are used in the open
via a residual current device (RCD) with an ac-
tuating current of 30 mA maximum. Do not op-
erate the machine in rain or moisture.
■ When working with the machine, always hold it
firmly with both hands and provide for a secure
stance.
■ Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
securely than by hand.
■ Always direct the cable to the rear away from
the machine.
■ Always switch the machine off and wait until it
has come to a standstill before placing it down.
■ For power outage or when the mains plug is
pulled, unlock the On/Off switch immediately
and turn it to the Off position. This prevents un-
controlled restarting.
■ The machine must be used only for dry cutting/
grinding.
■ For all work with the machine, the auxiliary
handle must be mounted.

■ When performing an operation where the
tool insert can run into concealed electric
lines, hold the machine by the insulated
handles only.
Contact with a “live” wire will make exposed
metal parts of the tool “live” and shock the op-
erator.
■ Use suitable detectors to determine if util-
ity 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.
■ For work with grinding or cutting discs, the pro-
tection guard 6 must be mounted. For work
with the rubber sanding plate 13 or with the
cup brush 16/disc brush/flap disc, the hand
guard 12 (accessory) is to be mounted.
■ Use dust extraction when working with stone.
The vacuum cleaner must be approved for ma-
sonry dust. When cutting stone, use the cutting
guide.
■ Do not work with materials containing asbes-
tos.
■ Use only grinding tools with a permissible
speed at least as high as the no-load speed of
the machine.
■ Check grinding tools before use. The grinding
tool must be properly mounted and turn freely.
Perform a test run for at least 30 seconds with-
out load. Do not use damaged, out-of-round or
vibrating grinding tools.
■ Protect the grinding tool from impact, shock
and grease.
■ Apply the machine to the workpiece only when
switched on.
■ Keep hands away from rotating grinding tools.
■ Pay attention to the direction of rotation. Al-
ways hold the machine so that sparks and
grinding dust fly away from the body.
■ When grinding metal, flying sparks are pro-
duced. Take care that no persons are endan-
gered. Due to danger of fire, no combustible
materials should be located in the vicinity
(spark flight zone).
■ Be careful when cutting grooves, e. g. in struc-
tural walls: See Information on Structures.
■ Blocking the cutting disc leads to jerking reac-
tion forces on the machine. In this case switch
off the machine immediately.
■ Observe the dimensions of the grinding discs.
The hole diameter must fit mounting
flange 8 (M 14), 19 (M 10). Do not use any re-
ducers or adapters.
■ Never use cutting discs for rough grinding. Do
not exert any lateral pressure on the cutting
discs.
■ Observe the manufacturer’s instructions for
mounting and using grinding tools.
■ Caution! The grinding tool runs on after the
machine is switched off.
■ Do not clamp the machine in a vice.
■ Never allow children to use the machine.
■ Bosch is only able to ensure perfect operation
of the machine if the original accessories in-
tended for it are used.
Slots in structural walls are subject to the Stand-
ard DIN 1053, Part 1 or country-specific regula-
tions.
These regulations are to be observed under all
circumstances. Before beginning work, consult
the responsible structural engineer, architect or
the construction supervisor.

Place the protection guard 6 onto the spindle col-
lar of the machine head as shown in the illustra-
tion. The encoding keys of the protection guard
must match with the respective recesses on the
spindle collar.
Press the protection guard onto the spindle collar
until the collar of the protection guard faces
against the flange of the machine and the encod-
ing keys engage in the circular groove at the spin-
dle collar.
Rotate the protection guard 6 in clockwise direc-
tion to the required position (working position).
Adjust the protection guard 6 in such a man-
ner that sparks are not emitted in the direc-
tion of the operator.
Note: Encoding keys on the protection guard 6
ensure that only a protection guard that fits the
machine type can be mounted.
Disassemble in the reverse sequence.
Auxiliary Handle
■ For all work with the machine, the auxiliary
handle must be mounted.
Screw the auxiliary handle 4 on the right or left of
the machine head depending on the working
method.
Vibration-dampening Auxiliary Handle
The vibration-dampening auxiliary handle re-
duces the vibrations, making operation more
comfortable and secure.
Do not make any alterations to the aux-
iliary handle.
Do not continue to use an auxiliary handle if it is
damaged.
Hand Guard
For work with the rubber sanding plate 13 or with
the cup brush 16/disc brush/flap disc, the hand
guard 12 (accessory) is to be mounted. The hand
guard 12 is fastened with the auxiliary handle 4.
■ Before any work on the machine itself, pull the
mains plug.
Use only grinding tools with a permissi-
ble speed at least as high as the no-load
speed of the machine.
Grinding and cutting discs become very
hot while working; do not touch until
they have cooled.

Observe the dimensions of the grinding
discs. The hole diameter must fit mounting
flange 8 (M 14), 19 (M 10). Do not use any re-
ducers or adapters.
When using a diamond cutting disc, take care
that the direction-of-rotation arrow on the dia-
mond cutting disc and the direction of rotation of
the machine (direction-of-rotation arrow on the
machine head) agree.
For mounting, see the illustration page.
Screw on the clamping nut 10 and tighten with
the two-pin spanner (see Section “Quick Clamp-
ing Nut”).

A properly tightened
undamaged, quick-
clamping nut can be
loosened by hand
turning the knurled
ring by hand in an an-
ticlockwise direction.
Never loosen a tight
quick-clamping nut
with pliers but use a
two-pin spanner. In-
sert the two-pin
spanner as shown in
the illustration.
All grinding tools mentioned in these operating in-
structions can be used.
The permissible speed [rpm] or the circumferen-
tial speed [m/s] of the grinding tools used must at
least match the values given in the table.
Therefore, always observe the permissible
rotational/circumferential speed on the label
of the grinding tool.
Observe correct mains voltage: The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching On and Off
To start the machine, press the On/Off switch 1
forward.
To lock-on, press the On/Off switch 1 down at
the front until it engages.
To switch off the machine, release the On/Off
switch 1 or, when the switch is locked, briefly
press down the On/Off switch 1 at the rear.
☞ Test run!
Check the grinding tool before use. The
grinding tool must be properly mounted
and rotate freely. Perform a test run of at
least 30 seconds without load. Do not use
damaged, out-of-round or vibrating grind-
ing tools.
Constant Electronic Control
(PWS 9-125 CE)
Constant electronic control holds the speed con-
stant at no-load and under load, and ensures uni-
form working performance.
Overload Protection (PWS 9-125 CE)
When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately and
allow to cool for approx. 30 seconds at the high-
est no-load speed.
Preselect the required speed using the thumb
wheel 2 according to the table following the sec-
tion “Tool Specifications” (reference values).
■ Clamp the workpiece if it does not remain sta-
tionary due to its own weight.
■ Do not strain the machine so heavily that it
comes to a standstill.
■ Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Rough Grinding
The best roughing results are
achieved when setting the machine
at an angle of 30° to 40°. Move the
machine back and forth with mod-
erate pressure. In this manner, the
workpiece will not become too hot,
does not discolour and no grooves
are formed.
Never use a cutting disc for roughing.

Flap Disc
With the flap disc (accessory), curved surfaces
and profiles (contour sanding) can be worked.
Flap discs have a considerably higher service life
than sanding sheets, lower noise level and lower
sanding temperatures.
Cutting
When cutting, do not press, tilt or
oscillate the machine. Work with
moderate feed, adapted to the ma-
terial being cut.
Do not reduce the speed of running
down cutting discs by applying
sideward pressure.
The direction in
which the cutting is
performed is impor-
tant.
The machine must
always work in an
up-grinding motion.
Therefore, never
move the machine in
the other direction!
Otherwise, the dan-
ger exists of it being
pushed uncon-
trolled out of the cut.
When cutting profiles and square pipes, it is best
to start with the smallest cross section.
Cutting Stone
■ The machine must be used only for dry
cutting/grinding.
It is best to use a diamond cutting disc. As a
safety measure against jamming, use the cutting
guide 17 with the special dust extraction protec-
tion guard.
Operate the machine with dust extraction only. In
addition, wear a dust mask.
The vacuum cleaner
must be approved for
the extraction of ma-
sonry dust.
Bosch provides suit-
able vacuum clean-
ers.
Switch on the ma-
chine and place the
front part of the cut-
ting guide on the
workpiece.
Slide the machine with moderate feed, adapted
to the material to be worked (Figure).
For cutting especially hard material, e. g., con-
crete with high pebble content, the diamond cut-
ting disc can overheat and become damaged as
a result. This is clearly indicated by circular
sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and al-
low the diamond cutting disc to cool by running
freely at no-load speed for a short time.
Noticeable decreasing work progress and circu-
lar sparking are indications of a diamond cutting
disc that has become dull. Briefly cutting into
abrasive material (e. g., lime-sand brick) can re-
sharpen the disc.
■ Before any work on the machine itself, pull the
mains plug.
■ For safe and proper working, always keep the
machine and the ventilation slots clean.
In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The
protective insulation of the machine can be
degraded. The use of a stationary extrac-
tion system is recommended in such cases
as well as frequently blowing out the venti-
lation slots and installing a residual current
device (RCD).
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an authorized after-sales
service centre for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit article number
given on the nameplate of the machine.
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this machine, it must
be disposed of safely.
