– 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.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Connecting the Dust Extraction (see figure A)
For sanding, always connect the dust extraction.
Remove the application tool/accessory when mounting the
dust extraction 19 (accessory).
If required, assemble the parts of the dust extraction 19 as
shown in the figure. Position the assembled dust extraction
onto the machine via the tool holder 8. Turn the dust extrac-
tion in such a manner that the cams of the dust extraction en-
gage into the corresponding recesses on the housing. Fasten
the dust extraction to the machine with the retaining clip 17
as shown in the figure.
Pay attention that the felt ring 16 is undamaged and faces
tightly against the sanding plate 14. Replace a damage felt
ring immediately.
Depending on machine version, place a vacuum hose 20 (ac-
cessory) either directly onto the vacuum connection 18 or cut
off the old hose end, screw the extraction adapter 21 (acces-
sory) onto the hose end and then place it directly onto the
vacuum connection 18. Connect the vacuum hose 20 with a
vacuum cleaner (accessory). An overview for the connection
of various vacuum cleaners can be found on the fold-out 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.
Operation

Starting Operation

Inserting the battery
 Use only original Bosch lithium-ion batteries with the
voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Insert the charged battery 2 into the handle until it can be felt
to engage and faces flush against the handle.
Switching On and Off
To start the machine, push the On/Off switch 7 forward so
that the "I" is indicated on the switch.
To switch off the machine, push the On/Off switch 7 toward
the rear so that the "0" is indicated on the switch.
To save energy, only switch the power tool on when using it.
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.

Note: If the machine should automatically switch off because
of a discharged or overheated battery, make sure to set the
machine's On/Off switch 7 to off. Charge the battery and al-
low it to cool down before restarting the machine. Otherwise
the battery can become damaged.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital stroke
rate 5, 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 determined through practical
testing.

Working Advice

 Before any work on the machine itself (e.g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 Wait until the machine has come to a standstill before
placing it down.
Note: Do not cover off the venting slots 6 of the machine while
working, as this reduces the working life of the machine.
Operating Principle
Due to the oscillating drive the application tool/accessory
oscillates up to 20000 times per minute at 2.8°. This allows
for precise work in narrow spaces.
Work with low and uniform application
pressure, otherwise, the working perfor-
mance 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
 Use only undamaged saw blades that are in perfect con-
dition. Bent or dull saw blades can break, negatively influ-
ence the cut, or lead to kickback.
 When sawing light building materials, observe the stat-
utory provisions and the recommendations of the ma-
terial suppliers.
 Plunge 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.
