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 5 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 3, 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.
When sawing and cutting harder materials, e.g., wood or met-
al, it is recommended to work with orbital stroke rate "5" or
"E"; for softer materials, such as plastic, orbital stroke rate "4"
is recommended.
When sanding harder materials, e.g., wood or metal, it is rec-
ommended to work with orbital stroke rate "5"; for softer ma-
terials, such as softwood, orbital stroke rate "4" is recom-
mended.
The Eco electronics are active at the maximum orbital stroke
rate "E": When the application tool is not subject to load, the
orbital stroke rate is automatically reduced (after approx.
1 s). The reduction extends the battery operating duration
per charge, and the reduced vibrations enable precise apply-
ing of the application tool onto the workpiece. As soon as load
is applied to the application tool again, the machine automat-
ically accelerates to the maximum orbital stroke rate.
The Eco electronics, however, are not suitable for sanding ac-
tivities. Instead, orbital stroke rate "5", which has the same
oscillation rate as setting "E" yet without the Eco electronics,
is suitable for sanding.

Working Advice

 Wait until the machine has come to a standstill before
placing it down.
 Before any work on the machine itself, pull the mains
plug.
Note: Do not cover off the venting slots 6 of the machine while
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.
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.
Bosch Power Tools
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.
To reduce the dust exposure and achieve better working re-
sults when sanding, use dust extraction as far as possible.
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.
Temperature-dependent Overload Protection
When using the machine as intended for, it cannot be subject
to overload. In case of excessive load or when not within the
permitted battery temperature range of –20 °C to +65 °C,
the machine switches off. In case of overload, the battery
charge-control indicator 4 will additionally flash red for a few
seconds.
