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 only undamaged saw blades that
are in perfect condition. Bent or dull saw blades can
break, negatively influence 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.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull the mains
plug.
For safe and proper working, always keep the machine
and ventilation slots clean.
Clean Riff application tools (accessory) regularly with a wire
brush.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
