Safety Notes
General Power Tool Safety Warnings
Read all safety warnings and all
instructions. Failure to follow
the warnings and instructions may result in elec-
tric shock, fire and/or serious injury.
Save all warnings and instructions for future
The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or
battery-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. Distrac-
tions 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.
Damaged 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 pow-
er tool. Do not use a power tool while you
are tired or under the influence of drugs,
alcohol or medication. A moment of inat-
tention while operating power tools may
result in serious personal injury.
b) Use personal protective equipment.
Always 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 injury.
e) Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the power tool in unex-
pected 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 connec-
tion of dust extraction and collection fa-
cilities, 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-
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
measures 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 mis-
alignment or binding of moving parts,
breakage of parts and any other condi-
tion that may affect the power tool’s op-
eration. 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 in-
structions, taking into account the work-
ing conditions and the work to be per-
formed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qual-
ified repair person using only identical
replacement parts. This will ensure that
the safety of the power tool is maintained.
Safety Warnings for Multi-function
f Hold power tool by insulated gripping sur-
faces, 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.
f Use the machine only for dry sanding. Pene-
tration of water into the machine increases
the risk of an electric shock.
f Keep hands away from the sawing range.
Do not reach under the workpiece. Contact
with the saw blade can lead to injuries.
f Use suitable detectors to determine if utili-
ty 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.
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 clamping devices or in a vice is held
more secure than by hand.
f Keep your workplace clean. Blends of mate-
rials are particularly dangerous. Dust from
light alloys can burn or explode.
f Never use the machine with a damaged
cable. Do not touch the damaged cable and
pull the mains plug when the cable is dam-
aged while working. Damaged cables in-
crease the risk of an electric shock.
f Wear protective gloves when changing
application tools/accessories. Application
tools/accessories become hot after pro-
longed usage.
f Do not scrape wetted materials (e. g. wall-
paper) or on moist surfaces. Penetration of
water into the machine increases the risk of
an electric shock. Page 14 Wednesday, May 12, 2010 12:48 PM
Page: 14

Bosch Power Tools 2 609 004 835 | (12.5.10)
f Do not treat the surface to be worked with
solvent-containing fluids. Materials being
warmed up by the scraping can cause toxic
vapours to develop.
f Exercise extreme caution when handling
the scraper. The accessory is very sharp;
danger of injury.
f 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 out-
lets, it should be cut off and an appropriate
plug fitted in its place by an authorised cus-
tomer service agent. The replacement plug
should have the same fuse rating as the origi-
nal plug.
The severed plug must be disposed of to
avoid a possible shock hazard and should nev-
er be inserted into a mains socket elsewhere.
Products sold in AUS and NZ only: Use a
residual current device (RCD) with a rated
residual current of 30 mA or less.

Noise/Vibration Information
Measured sound values determined according
to EN 60745.
Typically the A-weighted noise levels of the prod-
uct are: Sound pressure level 85 dB(A); Sound
power level 96 dB(A). Uncertainty K<1.5 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Sanding: Vibration emission value ah=6.4 m/s2
uncertainty K<2.0 m/s2
Cutting with plunge cut saw blade: Vibration
emission value ah=9.9 m/s2
, uncertainty
K<1.5 m/s2
Cutting with segmential saw blade: Vibration
emission value ah=5.0 m/s2
, uncertainty
K<1.5 m/s2
Scraping: Vibration emission value
ah=11.4 m/s2
, uncertainty K=2.2 m/s2
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 exposure.
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 in-
crease the exposure level over the total working
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
significantly 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.

Mounting/Replacing the Application Tool/
If required, remove an already mounted applica-
tion tool/accessory.
For removing the application tool/accessory
loosen the screw 9 with the allen key 10 and re-
move the tool.
Mount the application tool/accessory (e.g.
plunge cut saw blade 8) in such a way on the
tool holder 7 that the openings of the tool en-
gage into the cams of the tool holder.
For a safe and fatigue-free working position it is
possible to position the application tools/acces-
sories in any snap-in positions on the tool hold-
er. Position the tool in such a way that the de-
pressed centre points downwards (marking on
the tool is readable from above, see figure on
the graphics page).
Use the screw 9 to fasten the application tool/
accessory. Tightly fasten the screw 9 with the
allen key 10.
f Check the tight seating of the application
tool/accessory. Incorrect or not securely fas-
tened application tools/accessories can come
loose during operation and pose a hazard.

Dust/Chip Extraction
f Dusts 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
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Connecting the Dust Extraction
For sanding, always connect dust extraction.
Place a vacuum hose 4 (accessory) onto the vac-
uum connection 3. Connect the vacuum hose 4
with a vacuum cleaner (accessory). An overview
for the connection of various vacuum cleaners
can be found at the end of these instructions.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Starting Operation
f Observe 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, push the On/Off switch 1
forward so that the “I” is indicated on the switch.
To switch off the machine, push the On/Off
switch 1 toward the rear so that the “0” is indi-
cated on the switch.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the or-
bital stroke rate 2, 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
Note: Do not cover off the venting slots 6 of the
machine while working, as this reduces the
working life of the machine.
While working with HCS tools make sure that
the covering of the tools is undamaged.
Operating Principle
Due to the oscillating drive the application tool/
accessory swings up to 21000 times per minute
for 2.8°. This allows for precise work in narrow
Work with low and uniform appli-
cation pressure, otherwise, the
working performance will decline
and the application tool can be-
come blocked.
While working, move the machine
back and forth, so that the appli-
cation tool does not heat up ex-
cessively and become blocked. Page 19 Wednesday, May 12, 2010 12:48 PM

2 609 004 835 | (12.5.10) Bosch Power Tools
f Use undamaged faultless saw blades only.
Deformed, blunt saw blades or saw blades
that are otherwise damaged can break.
f When sawing light building materials, ob-
serve the statutory provisions and the rec-
ommendations of the material suppliers.
f Plunge cuts may only be applied to soft ma-
terials, such as wood, gypsum plaster
boards, etc.!
Before sawing with HCS saw blades in wood,
particle board, building materials, etc., check
these for foreign objects such as nails, screws,
or similar. If required, remove foreign objects or
use BIM saw blades.
Note: When separating wall tiles take into con-
sideration that the application tools/accesso-
ries wear heavily when used for longer periods
of time.
The removal rate and the sanding pattern are
primarily determined by the choice of sanding
sheet, the preset oscillation rate and the ap-
plied pressure.
Only flawless sanding sheets achieve good
sanding capacity and extend the service life of
the machine.
Pay attention to apply uniform sanding pres-
sure; this increases the working life of the sand-
ing 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
For precise on-the-spot sanding of edges, cor-
ners and hard to reach areas, it is also possible
to work only with the tip or an edge of the sand-
ing plate.
A sanding sheet that has been used for metal
should not be used for other materials.
Use only original Bosch sanding accessories.
For sanding, always connect dust extraction.
For scraping, select a high oscillation rate.
Work on a soft surface (e.g. wood) at a flat ange,
and apply only light pressure. Otherwise the
scraper can cut into the surface.
Maintenance and Service
Maintenance and Cleaning
f Before any work on the machine itself, pull
the mains plug.
f For safe and proper working, always keep
the machine and ventilation slots clean.
Clean Riff application tools (accessory) regularly
with a wire brush.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for Bosch power tools.
