General Power Tool Safety
Warnings
Read all safety warnings and all
instructions. Failure to follow the
warnings and instructions 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 mains-operated (corded) power tool or bat-
tery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Clut-
tered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) 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.
b) Avoid body contact with earthed or
grounded surfaces, such as pipes, radia-
tors, ranges and refrigerators. There is an
increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool
will increase the risk of electric shock.
d) 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. Dam-
aged or entangled cords increase the risk
of electric shock.
e) When operating a power tool outdoors,
use an extension cord suitable for out-
door use. Use of a cord suitable for out-
door use reduces the risk of electric shock.
f) If operating a power tool in a damp loca-
tion is unavoidable, use a residual current
device (RCD) protected supply. Use of an
RCD reduces the risk of electric shock.
3) Personal safety
a) 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 inattention while operating power tools
may result in serious personal injury.
b) Use personal protective equipment. Al-
ways wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protec-
tion used for appropriate conditions will
reduce personal injuries.
c) Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or bat-
tery 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.
d) Remove any adjusting key or wrench be-
fore turning the power tool on. A wrench
or a key left attached to a rotating part of
the power tool may result in personal inju-
ry.
e) Do not overreach. Keep proper footing
and balance at all times. This enables bet-
ter control of the power tool in unexpected
situations.
f) Dress properly. Do not wear loose cloth-
ing or jewellery. Keep your hair, clothing
and gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.

g) If devices are provided for the connection
of dust extraction and collection facili-
ties, ensure these are connected and
properly used. Use of dust collection can
reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the cor-
rect power tool for your application. The
correct power tool will do the job better
and safer at the rate for which it was de-
signed.
b) 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.
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjust-
ments, changing accessories, or storing
power tools. Such preventive safety meas-
ures reduce the risk of starting the power
tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these in-
structions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalign-
ment or binding of moving parts, break-
age 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.
f) Keep cutting tools sharp and clean. Prop-
erly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g) Use the power tool, accessories and tool
bits etc. in accordance with these instruc-
tions, taking into account the working
conditions and the work to be performed.
Use of the power tool for operations differ-
ent from those intended could result in a
hazardous situation.
5) Service
a) Have your power tool serviced by a quali-
fied repair person using only identical re-
placement parts. This will ensure that the
safety of the power tool is maintained.
Machine-specific
Safety Warnings
fUse the machine only for dry sanding. Pene-
tration of water into the machine increases
the risk of an electric shock.
fCaution, fire hazard! Avoid overheating the
object being sanded as well as the sander.
Always empty the dust collector before tak-
ing breaks. In unfavourable conditions, e. g.,
when sparks emit from sanding metals, sand-
ing debris in the dust bag, micro filter or pa-
per sack (or in the filter sack or filter of the
vacuum cleaner) can self-ignite. Particularly
when mixed with remainders of varnish, poly-
urethane or other chemical materials and
when the sanding debris is hot after long pe-
riods of working.
fSecure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
fKeep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.
fNever use the machine with a damaged ca-
ble. Do not touch the damaged cable and pull
the mains plug when the cable is damaged
while working. Damaged cables increase the
risk of an electric shock.

Bosch Power Tools 1 609 929 N27 | (11.12.07)
The vibration emission level given in this informa-
tion sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another. It
may be used for a preliminary assessment of ex-
posure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the
operator from the effects of vibration such as:
maintain the tool and the accessories, keep the
hands warm, organisation of work patterns.
Declaration of Conformity
We declare under our sole responsibility that the
product described under “Technical Data” is in
conformity with the following standards or
standardization documents: EN 60745 according
to the provisions of the directives 2004/108/EC,
98/37/EC (until Dec. 28, 2009), 2006/42/EC
(from Dec. 29, 2009 on).

Assembly
fBefore any work on the machine itself, pull
the mains plug.
Dust/Chip Extraction
fDusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
Integrated Dust Extraction with Dust Box
(see figures G1–G4)
Attach the dust box 4onto the extraction outlet
12 until it latches.
To empty the dust box 4, pull off the dust box
downward.
Before opening the dust box 4, it is recommend-
ed to loosen the dust from the filter element by
gently striking it against a firm support (as shown
in the figure).
Grasp the dust box 4by the recessed grip, fold
the filter element 13 upward and empty the dust
box. Clean the thin plates of the filter element 13
with a soft brush.
External Dust Extraction (see figure H)
Insert a vacuum hose 14 onto the extraction out-
let 12. Connect the vacuum hose 14 to a vacuum
cleaner. See the overview for connecting to vari-
ous vacuum cleaners at the end of these operat-
ing instructions.

The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
Replacing the Sanding Sheet
When attaching a new sanding sheet, remove any
dust or debris from the sanding plate 6(e. g. with
a brush).
To ensure optimum dust extraction, pay atten-
tion that the punched holes in the sanding sheet
match with the holes in the sanding plate.
Sanding Sheets with Velcro Backing
(see figure A)
The sanding plate 6is fitted with Velcro backing
for quick and easy fastening of sanding sheets
with Velcro adhesion.
Before attaching the sanding sheet 7, free the
Velcro backing of the sanding plate 6from any
debris by tapping against it in order to enable op-
timum adhesion.
Position the sanding sheet 7flush alongside one
edge of the sanding plate 6, then lay the sanding
sheet onto the sanding plate and press it against
it with a light turning motion in clockwise direc-
tion.
To remove the sanding sheet 7, grasp it at one of
the tips and pull it off from the sanding plate 6.
Sanding Sheets without Velcro Backing
(see figures B–D)
nPress the release button 8and keep it de-
pressed.
oGuide the sanding sheet 7to the stop under
the opened front clamping bracket 9and let
go of the release button 8again. Pay atten-
tion that the sanding sheet is clamped cen-
trally.
pPress the sanding sheet clamp 5inward and
pivot it to the stop.
qFold the sanding sheet 7firmly around the
sanding plate. Guide the other end of the
sanding sheet 7between the rear clamping
bracket and the red roller on the clamping
bracket 5.
rHold the sanding sheet tensely and press the
clamping bracket 5toward the sanding plate
to lock the sanding sheet.
Sanding sheets without holes, e. g. from rolls or
by the meter, can be punctured with the perfo-
rating tool 10 for use with dust extraction. For
this, press the machine with the mounted sand-
ing sheet onto the perforating tool (see figure E).
To remove the sanding sheet 7, loosen the
clamping bracket 5and pull out the sanding
sheet from the rear holding fixture. Press the re-
lease button 8and completely remove the sand-
ing sheet.

The sanding plate 6can be replaced, if required.
Unscrew the 4 screws 11 completely and remove
the sanding plate 6. Attach the new sanding plate
6and tighten the screws again.
Operation
Starting Operation
fObserve correct mains voltage! The voltage
of the power 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 machine, press the On/Off switch 2
and keep it depressed.
To lock the pressed On/Off switch 2, press the
lock-on button 3.
To switch off the machine, release the On/Off
switch 2or when it is locked with the lock-on but-
ton 3, briefly press the On/Off switch 2and then
release it.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the or-
bital stroke rate 1, you can preselect the required
orbital stroke rate, even during operation.
The required stroke rate depends on the material
and the working conditions and can be deter-
mined through practical testing.
Working Advice
fWait until the machine has come to a stand-
still before placing it down.
The removal capacity during sanding is mainly de-
termined by the selection of the sanding sheet as
well as the preselected orbital stroke rate.
Only flawless sanding sheets achieve good sand-
ing capacity and extend the service life of the ma-
chine.
Pay attention to apply uniform sanding pressure;
this increases the working life of the sanding
sheets.
Intensifiying the sanding pressure does not lead
to an increase of the sanding capacity, but to in-
creased wear of the machine and the sanding
sheet.
A sanding sheet that has been used for metal
should not be used for other materials.
Use only original Bosch sanding accessories.
Maintenance and Service
