Starting Operation

Inserting the battery
 Use only original Bosch lithium ion batteries with the
voltage listed on the nameplate of your power tool. Us-
ing other batteries can lead to injuries and pose a fire haz-
ard.
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
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 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.
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 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.
