Dust/Chip Extraction

 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– 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. Dust can
easily ignite.
Connecting the Dust Extraction
For sanding, always connect the dust extraction.
Place a vacuum hose 4 (accessory) onto the vacuum connec-
tion 3. Connect the vacuum hose 4 with a vacuum cleaner (ac-
cessory). An overview for the connection of various vacuum
cleaners can be found at the end of these instructions.
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

 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
To start the machine, push the On/Off switch 1 forward so
that the "I" is indicated on the switch.
To switch off the machine, push the On/Off switch 1 toward
the rear so that the "0" is indicated on the switch.
To save energy, only switch the power tool on when using it.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital stroke
rate 2, 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

 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 21000 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 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 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.
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.
