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
fKeepworkareaclean andwelllit.Clutteredor dark areas
invite accidents.
fDo 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.
fKeep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
fPower 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.
fAvoidbodycontact withearthedor groundedsurfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is
earthed or grounded.
fDo not expose power tools to rain or wet conditions.
Waterenteringapower toolwillincreasetheriskof electric
shock.
fDo 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.
fWhen 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.
fIf 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
fStay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a power
toolwhile you aretired orunder the influence of drugs,
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
fUse 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 injuries.
fPrevent 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. Car-
rying power tools with your finger on the switch or energis-
ing power tools that have the switch on invites accidents.
fRemove 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.
fDo not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
fDress 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.
fIf 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
fDo not force the power tool. Use the correct power tool
for your application. The correct power tool will do the
job better and safer at the rate for which it was designed.
fDo 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.
fDisconnect 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.
fStore 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.
fMaintain 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,havethepowertoolrepairedbeforeuse.Many
accidents are caused by poorly maintained power tools.
fKeep cutting tools sharp and clean. Properly maintained
cuttingtools withsharpcutting edgesareless likelyto bind
and are easier to control.
fUse 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
fHaveyour powertool serviced bya qualifiedrepair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Safety Warnings for Multi-function Tools
fHold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting ac-
cessory contacting a “live” wire may make exposed metal
partsofthepower tool “live”andcouldgivetheoperator an
electric shock.
fUse the machine only for dry sanding. Penetrationofwa-
ter into the machine increases the risk of an electric shock.
fCaution, fire hazard! Avoid overheating the object be-
ing sanded as well as the sander. Always empty the
dust collector before taking breaks. In unfavourable
conditions, e.g., when sparks emit from sanding metals,
sanding debris in the dust bag, micro filter or paper sack
(or in the filter sack or filter of the vacuum cleaner) can
self-ignite.Particularly whenmixedwith remaindersof var-
nish, polyurethane or other chemical materials and when
the sanding debris is hot after long periods of working.
fKeep hands away from the sawing range. Do not reach
undertheworkpiece.Contactwiththesawbladecanlead
to injuries.
fUse suitable detectors to determine if utility lines are
hiddenin thework area or call thelocal utilitycompany
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.
fWhen 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.
fSecure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
fWear protective gloves when changing application
tools/accessories.Applicationtools/accessoriesbecome
hot after prolonged usage.
fDo not scrape wetted materials (e.g. wallpaper) or on
moist surfaces. Penetration of water into the machine in-
creases the risk of an electric shock.
fDo not treat the surface to be worked with solvent-con-
taining fluids. Materials being warmed up by the scraping
can cause toxic vapours to develop.
fUse extreme caution when handling blades and scrap-
ers. The application tools are very sharp. Danger of injury.
fProducts 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 outlets, it should
be cut off and an appropriate plug fitted in its place by an
authorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never 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.

The vibration emission 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
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main
applications of the tool. However if the tool is used for differ-
ent applications, with different accessories or poorly main-
tained, the vibration emission may differ. This may signifi-
cantly 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 may sig-
nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
fromtheeffects ofvibrationsuch as:maintainthe tool andthe
accessories, keep hands warm, organise work patterns.

Dust/Chip Extraction
fDusts 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 extractionsystem suitable
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.
fPrevent dust accumulation at the workplace. Dusts can
easily ignite.
Connecting the Dust Extraction (see figure E)
Thedustextraction18is intended onlywhenworkingwiththe
sanding plate 10; it is not of use in combination with other ap-
plication tools.
For sanding, always connect the dust extraction.
To mount the dust extraction 18 (accessory), remove the ap-
plication tool and the depth stop 12.
Slide the dust extraction 18 over and beyond the tool holder
8to the stop onto the gear head of the power tool. Insert fas-
tening screw 17 into the corresponding recess on the hous-
ing. To lock the screw, turn it to the position.
Pay attention that the felt ring 19 is undamaged and faces
tightly against the sanding plate 10. Replace a damage felt
ring immediately.
Place a vacuum hose 15 (accessory) onto the vacuum con-
nection 16. Connect the vacuum hose 15 with a vacuum
cleaner (accessory).
Anoverviewforconnectingtovariousvacuumcleanerscan be
found on the graphics page.
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.
To remove the dust extraction 18, turn fastening screw 17 to
the position and pull the dust extraction from the gear
head of the power tool.
Operation
Starting Operation
fObserve the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
Switching On and Off
To start the machine, push the On/Off switch 2forward so
that the “I” is indicated on the switch.
To switch off the machine, push the On/Off switch 2toward
the rear so that the “0” is indicated on the switch.
When not using the power tool, switch it off in order to save
energy.
Constant Electronic Control
The constant electronic control keeps the stroke rate almost
constant under load conditions and ensures a uniform work-
ing performance.
Soft starting
The electronic soft starting feature limits the torque upon
switching on and increases the working life of the motor.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital stroke
rate3,youcanpreselect the requiredorbitalstrokerate,even
during operation.
The required stroke rate depends on the material and the
working conditions and can be determined through practical
testing.
When sawing, cutting and sanding harder materials, e.g.,
wood or metal, it is recommended to work with orbital stroke
rate “6”; for softer materials, such as plastic, orbital stroke
rate “4” is recommended.
Working Advice
fWait until the machine has come to a standstill before
placing it down.
fBefore any work on the machine itself, pull the mains
plug.
Note:Donotcover offtheventingslots4of the machinewhile
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.

Bosch Power Tools 2 609 006 340 | (23.7.12)
Operating Principle
Due to the oscillating drive the application tool/accessory
swingsup to 20000times perminutefor 2.8°.Thisallows for
precise work in narrow spaces.
Work with low and uniform application
pressure, otherwise, the working perform-
ance will decline and the application tool
can become blocked.
While working, move the machine back and
forth, so that the application tool does not
heat up excessively and become blocked.
Sawing
fUse only undamaged saw blades that
are in perfect condition. Bent or dull saw blades can
break, negatively influence the cut, or lead to kickback.
fWhen sawing light building materials, observe the stat-
utory provisions and the recommendations of the ma-
terial suppliers.
fPlunge cuts may only be applied to soft materials, 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 ob-
jects or use BIM saw blades.
Separating
Note: When separating wall tiles take into consideration that
the application tools/accessories wear heavily when used for
longer periods of time.
Sanding
The removal rate and the sanding pattern are primarily deter-
mined by the choice of sanding sheet, the preset oscillation
rate and the applied pressure.
Only flawless sanding sheets achieve good sanding capacity
and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this increas-
es the working life of the sanding sheets.
Intensifiying the sanding pressure does not lead to an in-
crease of the sanding capacity, but to increased wear of the
machine and the sanding sheet.
Forpreciseon-the-spot sanding ofedges,corners andhardto
reach areas, it is also possible to work only with the tip or an
edge of the sanding plate.
When selectively sanding on the spot, the sanding sheet can
heat up considerably. Reduce the orbital stroke rate and the
sanding pressure, and allow the sanding sheet to cool down
regularly.
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 the dust extraction.
Scraping
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.
