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
(accessory) either directly onto the vacuum connection 18 or
cut off the old hose end, screw the extraction adapter 21
(accessory) 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.
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

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
swings up to 20000 times per minute for 2.8°. This allows
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
Use undamaged faultless saw blades only. Deformed,
blunt saw blades or saw blades that are otherwise dam-
aged can break.
When sawing light building materials, observe the
statutory provisions and the recommendations of the
material 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.
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.
For precise on-the-spot sanding of edges, corners and hard to
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 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 dust extraction.
