Safety Instructions

General Power Tool Safety Warnings

WARNING Read all safety warnings, instructions,
illustrations and specifications
provided with this power tool. Failure to follow all instructions
listed below 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 battery-operated (cordless)
power tool.

Work area safety

▶ Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
▶ 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.
▶ Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
▶ 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.
▶ Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
▶ Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
▶ 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 or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
▶ When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable
for outdoor use reduces the risk of electric shock.
▶ If operating a power tool in a damp location is unavoidable,
use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric
shock.

Personal safety

▶ 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.
▶ Use personal protective equipment. Always wear eye
protection. Protective equipment such as a dust mask,
non-skid safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce personal injuries.
▶ 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 energizing
power tools that have the switch on invites accidents.
▶ Remove any adjusting key or wrench before 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.
▶ Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
▶ Dress properly. Do not wear loose clothing or jewelry.
Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
▶ If devices are provided for the connection of dust extraction
and collection facilities, ensure these are connected
and properly used. Use of dust collection can reduce
dust-related hazards.
▶ Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool
safety principles. A careless action can cause severe injury
within a fraction of a second.
Power tool use and care
▶ Do 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.
▶ 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.
▶ Disconnect the plug from the power source and/or remove
the battery pack, if detachable, 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.
▶ 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.
▶ Maintain power tools and accessories. Check for misalignment
or binding of moving parts, breakage 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.

▶ Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
▶ Use the power tool, accessories and tool bits etc. in
accordance 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.
▶ Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
Battery tool use and care
▶ Recharge only with the charger specified by the manufacturer.
A charger that is suitable for one type of battery
pack may create a risk of fire when used with another
battery pack.
▶ Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a
risk of injury and fire.
▶ When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause burns
or a fire.
▶ Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally occurs,
flush with water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the battery
may cause irritation or burns.
▶ Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behavior resulting in fire, explosion or risk
of injury.
▶ Do not expose a battery pack or tool to fire or excessive
temperature. Exposure to fire or temperature above
130°C may cause explosion.
▶ Follow all charging instructions and do not charge the
battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outside the specified range may damage
the battery and increase the risk of fire.
Service
▶ Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
▶ Never service damaged battery packs. Service of battery
packs should only be performed by the manufacturer
or authorized service providers.
Safety information for multi-cutters
▶ Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring. Cutting accessory contacting

live” wire may make exposed metal parts of the
power tool “live” and could give the operator an electricshock.
▶ Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding
the workpiece by hand or against your body leaves it unstable
and may lead to loss of control.
▶ Only use the power tool for dry sanding. Water entering
a power tool will increase the risk of electric shock.
▶ Warning: Danger of fire! Avoid overheating the workpiece
and the sander. Always empty the dust collector
before taking a break from work. Sanding dust in the
dust bag, microfilter, paper bag (or in the filter bag or vacuum
cleaner filter) can spontaneously combust under
certain conditions, for example if flying sparks are created
when sanding metals. This risk is increased if the
sanding dust is mixed with paint or polyurethane residue
or with other chemical substances and if the workpiece is
hot as a result of prolonged work.
▶ Keep hands away from the sawing area. Do not reach
under the workpiece. Contact with the saw blade can
lead to injuries.
▶ Clean the air vents on your power tool regularly. The
motor’s fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
▶ Use suitable detectors to determine if there are hidden
supply lines or contact the local utility company
for assistance. Contact with electric cables can cause
fire and electric shock. Damaging gas lines can lead to explosion.
Breaking water pipes causes property damage.
▶ Hold the power tool firmly with both hands and make
sure you have a stable footing. The power tool can be
more securely guided with both hands.
▶ When changing the application tool, wear protective
gloves. Application tools can become hot when used for
prolonged periods of time.
▶ Do not scrape any dampened materials (e.g. wallpaper)
or on damp surfaces. Water entering a power tool
increases the risk of electric shock.
▶ Do not treat the surface you will be working on with
any fluids that contain solvents. Poisonous vapours
may develop due to the materials heating up when being
scraped.
▶ Take particular care when handling scrapers and
blades. The application tools are very sharp. Danger of injury.
▶ In case of damage and improper use of the battery, vapours
may be emitted. The battery can set alight or explode.
Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
▶ Do not open the battery. There is a risk of short-circuiting.
▶ The battery can be damaged by pointed objects such
as nails or screwdrivers or by force applied externally.

An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
▶ Only use the battery with products from the manufacturer.
This is the only way in which you can protect the
battery against dangerous overload.
Protect the battery against heat, e.g. against
continuous intense sunlight, fire, dirt, water
and moisture. There is a risk of explosion and
short-circuiting.

Noise/Vibration Information
Noise emission values determined according
to EN 62841‑2‑4.
Typically, the A-weighted sound pressure level of the power
tool is 80 dB(A). Uncertainty K = 3 dB. The noise level when
working can exceed the volume stated. Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K
determined according to EN 62841‑2‑4:
Sanding: ah = 3.4 m/s2, K = 1.5 m/s2,
Cutting with plunge cut saw blade: ah = 2.9 m/s2,
K = 1.5 m/s2,
Cutting with segmental saw blade: ah = 3 m/s2,
K = 1.5 m/s2.
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardized measuring procedure and may be used to compare
power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent
the main applications of the power tool. However, if the
power tool is used for other applications, with different application
tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.

This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the operator
from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.

Fitting/changing the application tool
Remove the application tool if one has already been fitted.
To do so, open the SDS lever (7) all the way. The application
tool/accessory will be ejected.
Position the required application tool (e.g. plunge cut saw
blade (12)) on the tool holder (8) so that the depressed

centre is facing downwards (see figure on the graphics page,
text on the application tool should be legible from above).
When doing so, place the application tool/accessory in a position
which is convenient for the job at hand. Twelve positions
offset by 30° are possible for this.

Press the application tool in the required position firmly onto
the clamping jaws of the tool holder until it locks automatically.
▶  Check that the application tool is seated securely. Application
tools that are attached incorrectly or are not securely
fixed in place may come loose during operation,
thereby putting you at risk.

Mounting and adjusting the depth stop

The depth stop (11) can be used when working with segment
and plunge cut saw blades.
Remove the application tool if one has already been fitted.
Slide the depth stop (11) into the required working position
over the tool holder (8) and onto the collar of the power tool
as far as it will go. Allow the depth stop to engage. Twelve
positions offset by 30° are possible for this.
Set the depth you wish to work at. Push the clamping lever
(10) of the depth stop shut to fix the depth stop in position.

Selecting a sanding sheet

Different sanding sheets are available, depending on the material you are working with and the required surface removal rate:

selecting method

Attaching/changing the sanding sheet on the sanding plate

The sanding plate (14) is fitted with a hook-and-loop fastening,
allowing sanding sheets with a hook-and-loop backing to
be secured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (14)
before fitting the sanding sheet (15) to facilitate maximum
adhesion.
Position the sanding sheet (15) so that it is flush with one
side of the sanding plate (14), then place the sanding sheet
on the sanding plate and press it on firmly.
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet are aligned with the
drilled holes in the sanding plate.
To remove the sanding sheet (15), take hold of it by an edge
and pull it away from the sanding plate (14).
You can use all sanding sheets, polishing and cleaning
fleeces from the Delta 93 mm series in the Bosch range of
accessories.
Sanding accessories such as fleece/polishing felt are attached
to the sanding plate in the same way.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reactions
and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials containing
asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the material
wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
▶  Avoid dust accumulation at the workplace. Dust can
easily ignite.

Connecting the dust extraction system (see figure A)

The dust extraction system (13) is only designed for use
with the sanding plate (14); it serves no purpose when used
together with other application tools.
Always connect a dust extraction system for sanding.
Remove the application tool and the depth stop (11) for fitting
the dust extraction system (13) (accessory).
Slide the dust extraction system (13) as far as it will go over

When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.

Operation

Starting Operation

Switching on/off
▶  Make sure that you are able to press the On/Off switch
without releasing the handle.
To switch on the work light, slide the on/off switch (1) forwards
so that appears on the switch. The work light improves
visibility in the immediate work area.
▶  Do not look directly into the work light; it can blind
you.
To switch on the power tool, slide the on/off switch (1) further
forwards so that “I” appears on the switch.
To switch off the power tool and the work light, slide the on/
off switch (1) backwards so that “0” appears on the switch.
Note: If the power tool shuts down automatically because
the battery is flat or overheated, switch the power tool off
using the on/off switch (1).
Charge the battery or let it cool down before switching the
power tool on again. Failure to do so can damage the battery.

Preselecting the orbital stroke rate
You can even preselect the required orbital stroke rate during
operation using the orbital stroke rate preselection
thumbwheel (5).
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using practical
tests.
Orbital stroke rate level “6” is recommended for sawing, cutting
and sanding harder materials, such as wood or metal;

orbital stroke rate level “4” is recommended for softer materials,
such as plastic.
Note: For certain application tools (e.g. sanding and RIFF
application tools) the orbital stroke rate should be limited to
a maximum of 2/3. If the orbital stroke rate is too high, this
will considerably increase the wear on the application tool
and can also lead to premature breakdown. Please take note
of the information on the application tools or on the packaging
of the application tool.

Working Advice

▶  Remove the battery from the power tool before carrying
out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be removed
for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
▶  Always wait until the power tool has come to a complete
stop before placing it down.
Note: Do not keep the ventilation slots (4) on the power tool
closed when working as this will reduce the service life of the
power tool.

Operating principle
The oscillating drive causes the application tool to oscillate
back and forth up to 20000 times per minute. This enables
precise work in the tightest of spaces.

Use a consistent, low contact pressure when
performing work; otherwise, the performance
will be impaired and the application tool may
jam.

While working, move the power tool back and
forth to prevent the application tool overheating
and jamming.

Sawing

▶  Use only undamaged saw blades that are in perfect
condition. Bent or dull saw blades can break, negatively
influence the cut, or lead to kickback.
▶  When sawing lightweight materials, take into account
the statutory provisions and recommendations of the
material manufacturers.
▶  Plunge cuts may only be applied to soft materials,
such as wood, gypsum board, etc.

Before using HCS saw blades to saw into wood, chipboard,
building materials, etc., check these saw blades for foreign
objects, such as nails, screws, etc. Remove the foreign objects
as required or use bi-metal saw blades.

Cutting
Note: When cutting wall tiles, please bear in mind that the
application tools are subject to high wear if used for extended
periods.

Sanding
The material removal rate and sanding result are primarily
determined by the choice of sanding sheet, the preselected
orbital stroke rate level and the contact pressure.

Only immaculate sanding sheets achieve good sanding performance
and make the power tool last longer.
Be sure to apply consistent contact pressure in order to increase
the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to
increased sanding performance, rather it will cause more
severe wear of the power tool and of the sanding sheet.
To sand corners, edges and hard-to-reach areas accurately,
you can also work with the tips alone or with an edge of the
sanding plate.
The sanding sheet may heat up significantly when used to
sand specific points rather than entire surfaces. Reduce the
orbital stroke rate and contact pressure and allow the sanding
sheet to cool down at regular intervals.
Do not use a sanding sheet for other materials after it has
been used to work on metal.
Use only original Bosch-sanding accessories.
Always connect a dust extraction system for sanding.

Scraping

Select a high orbital stroke rate level for scraping.
Work on a soft surface (e.g. wood) at a flat angle and with
low contact pressure. Failure to do so may cause the scraper
to cut into the surface underneath.

Temperature-dependent overload protection

In normal conditions of use, the power tool cannot be overloaded.
If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced
or the power tool switches off. At reduced speed, the power
tool will run again at full speed once the permitted battery
temperature is reached or the load is reduced. If it automatically
shuts down, switch the power tool off, allow the battery
to cool down, then switch the power tool back on.

Maintenance and Service

Maintenance and Cleaning

▶  Remove the battery from the power tool before carrying
out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be removed
for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
▶  To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
Regularly clean Riff application tools (accessories) using a
wire brush.

General Power Tool Safety Warnings

WARNING Read all safety warnings, instructions,
illustrations and specifications
provided with this power tool. Failure to follow all instructions
listed below 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 battery-operated (cordless)
power tool.

Work area safety

▶ Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
▶ 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.
▶ Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
▶ 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.
▶ Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
▶ Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
shock.
▶ 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 or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
▶ When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable
for outdoor use reduces the risk of electric shock.
▶ If operating a power tool in a damp location is unavoidable,
use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric
shock.

Personal safety

▶ 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.
▶ Use personal protective equipment. Always wear eye
protection. Protective equipment such as a dust mask,
non-skid safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce personal injuries.
▶ 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 energizing
power tools that have the switch on invites accidents.
▶ Remove any adjusting key or wrench before 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.
▶ Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
▶ Dress properly. Do not wear loose clothing or jewelry.
Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
▶ If devices are provided for the connection of dust extraction
and collection facilities, ensure these are connected
and properly used. Use of dust collection can reduce
dust-related hazards.
▶ Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool
safety principles. A careless action can cause severe injury
within a fraction of a second.
Power tool use and care
▶ Do 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.
▶ 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.
▶ Disconnect the plug from the power source and/or remove
the battery pack, if detachable, 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.
▶ 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.
▶ Maintain power tools and accessories. Check for misalignment
or binding of moving parts, breakage 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.

▶ Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
▶ Use the power tool, accessories and tool bits etc. in
accordance 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.

Battery tool use and care
▶ Recharge only with the charger specified by the manufacturer.
A charger that is suitable for one type of battery
pack may create a risk of fire when used with another
battery pack.
▶ Use power tools only with specifically designated battery
packs. Use of any other battery packs may create a
risk of injury and fire.
▶ When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause burns
or a fire.
▶ Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally occurs,
flush with water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the battery

packs should only be performed by the manufacturer
or authorized service providers.
Safety information for multi-cutters
▶ Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory
may contact hidden wiring. Cutting accessory contacting

live” wire may make exposed metal parts of the
power tool “live” and could give the operator an electricshock.
▶ Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding
the workpiece by hand or against your body leaves it unstable
and may lead to loss of control.
▶ Only use the power tool for dry sanding. Water entering
a power tool will increase the risk of electric shock.
▶ Warning: Danger of fire! Avoid overheating the workpiece
and the sander. Always empty the dust collector
before taking a break from work. Sanding dust in the
dust bag, microfilter, paper bag (or in the filter bag or vacuum
cleaner filter) can spontaneously combust under
certain conditions, for example if flying sparks are created
when sanding metals. This risk is increased if the
sanding dust is mixed with paint or polyurethane residue
or with other chemical substances and if the workpiece is
hot as a result of prolonged work.
▶ Keep hands away from the sawing area. Do not reach
under the workpiece. Contact with the saw blade can
lead to injuries.
▶ Clean the air vents on your power tool regularly. The
motor’s fan will draw the dust inside the housing and excessive
accumulation of powdered metal may cause electrical
hazards.
▶ Use suitable detectors to determine if there are hidden
supply lines or contact the local utility company
for assistance. Contact with electric cables can cause
fire and electric shock. Damaging gas lines can lead to explosion.
Breaking water pipes causes property damage.
▶ Hold the power tool firmly with both hands and make
sure you have a stable footing. The power tool can be
more securely guided with both hands.
▶ When changing the application tool, wear protective
gloves. Application tools can become hot when used for
prolonged periods of time.
▶ Do not scrape any dampened materials (e.g. wallpaper)
or on damp surfaces. Water entering a power tool
increases the risk of electric shock.
▶ Do not treat the surface you will be working on with
any fluids that contain solvents. Poisonous vapours
may develop due to the materials heating up when being
scraped.
▶ Take particular care when handling scrapers and
blades. The application tools are very sharp. Danger of injury.
▶ In case of damage and improper use of the battery, vapours
may be emitted. The battery can set alight or explode.
Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
▶ Do not open the battery. There is a risk of short-circuiting.
▶ The battery can be damaged by pointed objects such
as nails or screwdrivers or by force applied externally.

An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
▶ Only use the battery with products from the manufacturer.
This is the only way in which you can protect the
battery against dangerous overload.
Protect the battery against heat, e.g. against
continuous intense sunlight, fire, dirt, water
and moisture. There is a risk of explosion and
short-circuiting.

Noise/Vibration Information
Noise emission values determined according
to EN 62841‑2‑4.
Typically, the A-weighted sound pressure level of the power
tool is 80 dB(A). Uncertainty K = 3 dB. The noise level when
working can exceed the volume stated. Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K
determined according to EN 62841‑2‑4:
Sanding: ah = 3.4 m/s2, K = 1.5 m/s2,
Cutting with plunge cut saw blade: ah = 2.9 m/s2,
K = 1.5 m/s2,
Cutting with segmental saw blade: ah = 3 m/s2,
K = 1.5 m/s2.
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardized measuring procedure and may be used to compare
power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value represent
the main applications of the power tool. However, if the
power tool is used for other applications, with different application
tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.

This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the operator
from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.

Fitting/changing the application tool
Remove the application tool if one has already been fitted.
To do so, open the SDS lever (7) all the way. The application
tool/accessory will be ejected.
Position the required application tool (e.g. plunge cut saw
blade (12)) on the tool holder (8) so that the depressed

centre is facing downwards (see figure on the graphics page,
text on the application tool should be legible from above).
When doing so, place the application tool/accessory in a position
which is convenient for the job at hand. Twelve positions
offset by 30° are possible for this.

Press the application tool in the required position firmly onto
the clamping jaws of the tool holder until it locks automatically.
▶  Check that the application tool is seated securely. Application
tools that are attached incorrectly or are not securely
fixed in place may come loose during operation,
thereby putting you at risk.

Mounting and adjusting the depth stop

The depth stop (11) can be used when working with segment
and plunge cut saw blades.
Remove the application tool if one has already been fitted.
Slide the depth stop (11) into the required working position
over the tool holder (8) and onto the collar of the power tool
as far as it will go. Allow the depth stop to engage. Twelve
positions offset by 30° are possible for this.
Set the depth you wish to work at. Push the clamping lever
(10) of the depth stop shut to fix the depth stop in position.

Selecting a sanding sheet

Different sanding sheets are available, depending on the material you are working with and the required surface removal rate:

selecting method

Attaching/changing the sanding sheet on the sanding plate

The sanding plate (14) is fitted with a hook-and-loop fastening,
allowing sanding sheets with a hook-and-loop backing to
be secured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (14)
before fitting the sanding sheet (15) to facilitate maximum
adhesion.
Position the sanding sheet (15) so that it is flush with one
side of the sanding plate (14), then place the sanding sheet
on the sanding plate and press it on firmly.
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet are aligned with the
drilled holes in the sanding plate.
To remove the sanding sheet (15), take hold of it by an edge
and pull it away from the sanding plate (14).
You can use all sanding sheets, polishing and cleaning
fleeces from the Delta 93 mm series in the Bosch range of
accessories.
Sanding accessories such as fleece/polishing felt are attached
to the sanding plate in the same way.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reactions
and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials containing
asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the material
wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
▶  Avoid dust accumulation at the workplace. Dust can
easily ignite.

Connecting the dust extraction system (see figure A)

The dust extraction system (13) is only designed for use
with the sanding plate (14); it serves no purpose when used
together with other application tools.
Always connect a dust extraction system for sanding.
Remove the application tool and the depth stop (11) for fitting
the dust extraction system (13) (accessory).
Slide the dust extraction system (13) as far as it will go over
the tool holder (8) onto the collar of the power tool. Turn the
dust extraction system to the required position (not directly
under the power tool). Push the clamping lever (16) shut to
fix the dust extraction system in position.
Attach the dust extraction adapter (18) of the dust extraction
hose (19) to the dust extraction outlet (17). Connect
the dust extraction hose (19) to a dust extractor (accessory).
You will find an overview of how to connect various dust extractors
at the end of these operating instructions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.

Operation

Starting Operation

Switching on/off
▶  Make sure that you are able to press the On/Off switch
without releasing the handle.
To switch on the work light, slide the on/off switch (1) forwards
so that appears on the switch. The work light improves
visibility in the immediate work area.
▶  Do not look directly into the work light; it can blind
you.
To switch on the power tool, slide the on/off switch (1) further
forwards so that “I” appears on the switch.
To switch off the power tool and the work light, slide the on/
off switch (1) backwards so that “0” appears on the switch.
Note: If the power tool shuts down automatically because
the battery is flat or overheated, switch the power tool off
using the on/off switch (1).
Charge the battery or let it cool down before switching the
power tool on again. Failure to do so can damage the battery.

Preselecting the orbital stroke rate
You can even preselect the required orbital stroke rate during
operation using the orbital stroke rate preselection
thumbwheel (5).
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using practical
tests.
Orbital stroke rate level “6” is recommended for sawing, cutting
and sanding harder materials, such as wood or metal;

orbital stroke rate level “4” is recommended for softer materials,
such as plastic.
Note: For certain application tools (e.g. sanding and RIFF
application tools) the orbital stroke rate should be limited to
a maximum of 2/3. If the orbital stroke rate is too high, this
will considerably increase the wear on the application tool
and can also lead to premature breakdown. Please take note
of the information on the application tools or on the packaging
of the application tool.

Working Advice

▶  Remove the battery from the power tool before carrying
out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be removed
for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
▶  Always wait until the power tool has come to a complete
stop before placing it down.
Note: Do not keep the ventilation slots (4) on the power tool
closed when working as this will reduce the service life of the
power tool.

Operating principle
The oscillating drive causes the application tool to oscillate
back and forth up to 20000 times per minute. This enables
precise work in the tightest of spaces.

Use a consistent, low contact pressure when
performing work; otherwise, the performance
will be impaired and the application tool may
jam.

While working, move the power tool back and
forth to prevent the application tool overheating
and jamming.

Sawing

▶  Use only undamaged saw blades that are in perfect
condition. Bent or dull saw blades can break, negatively
influence the cut, or lead to kickback.
▶  When sawing lightweight materials, take into account
the statutory provisions and recommendations of the
material manufacturers.
▶  Plunge cuts may only be applied to soft materials,
such as wood, gypsum board, etc.

Before using HCS saw blades to saw into wood, chipboard,
building materials, etc., check these saw blades for foreign
objects, such as nails, screws, etc. Remove the foreign objects
as required or use bi-metal saw blades.

Cutting
Note: When cutting wall tiles, please bear in mind that the
application tools are subject to high wear if used for extended
periods.

Sanding
The material removal rate and sanding result are primarily
determined by the choice of sanding sheet, the preselected
orbital stroke rate level and the contact pressure.

Only immaculate sanding sheets achieve good sanding performance
and make the power tool last longer.
Be sure to apply consistent contact pressure in order to increase
the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to
increased sanding performance, rather it will cause more
severe wear of the power tool and of the sanding sheet.
To sand corners, edges and hard-to-reach areas accurately,
you can also work with the tips alone or with an edge of the
sanding plate.
The sanding sheet may heat up significantly when used to
sand specific points rather than entire surfaces. Reduce the
orbital stroke rate and contact pressure and allow the sanding
sheet to cool down at regular intervals.
Do not use a sanding sheet for other materials after it has
been used to work on metal.
Use only original Bosch-sanding accessories.
Always connect a dust extraction system for sanding.

Scraping

Select a high orbital stroke rate level for scraping.
Work on a soft surface (e.g. wood) at a flat angle and with
low contact pressure. Failure to do so may cause the scraper
to cut into the surface underneath.

Temperature-dependent overload protection

In normal conditions of use, the power tool cannot be overloaded.
If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced
or the power tool switches off. At reduced speed, the power
tool will run again at full speed once the permitted battery
temperature is reached or the load is reduced. If it automatically
shuts down, switch the power tool off, allow the battery
to cool down, then switch the power tool back on.

Maintenance and Service

Maintenance and Cleaning

▶  Remove the battery from the power tool before carrying
out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be removed
for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
▶  To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
Regularly clean Riff application tools (accessories) using a
wire brush.
