To switch off the power tool, slide the on/off switch (1)
backwards so that "0" appears on the switch.
Preselecting the orbital stroke rate
You can even preselect the required orbital stroke rate dur-
ing operation using the orbital stroke rate preselection
thumbwheel (2).
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
Orbital stroke rate level "6" is recommended for sawing, cut-
ting and sanding harder materials, such as wood or metal;
orbital stroke rate level "4" is recommended for softer ma-
terials, such as plastic.

Practical Advice

Pull the plug out of the socket before carrying out any
u
work on the power tool.
Always wait until the power tool has come to a com-
u
plete stop before placing it down.
Note: Do not keep the ventilation slots (3) on the power tool
closed when working as this will reduce the service life of the
power tool.
Operating principle
The oscillating drive causes the application tool to oscillate
back and forth by 2.8° up to 20000 times per minute. This
enables precise work in the tightest of spaces.
Use a consistent, low contact pressure
when performing work; otherwise, the
performance will be impaired and the ap-
plication tool may jam.
While working, move the power tool back
and forth to prevent the application tool
overheating and jamming.
Sawing
Use only undamaged saw blades that are in perfect
u
condition. Bent or dull saw blades can break, negatively
influence the cut, or lead to kickback.
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Plunge cuts may only be applied to soft materials,
u
such as wood, gypsum board, etc.
Before using HCS saw blades to saw into wood, chipboard,
building materials, etc., check these saw blades for foreign
objects, such as nails, screws, etc. Remove the foreign ob-
jects as required or use bi-metal saw blades.
Cutting
Note: When cutting wall tiles, please bear in mind that the
application tools are subject to high wear if used for exten-
ded periods.
Bosch Power Tools
Sanding
The material removal rate and sanding result are primarily
determined by the choice of sanding sheet, the preselected
orbital stroke rate level and the contact pressure.
Only immaculate sanding sheets achieve good sanding per-
formance and make the power tool last longer.
Be sure to apply consistent contact pressure in order to in-
crease the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to
increased sanding performance, rather it will cause more
severe wear of the power tool and of the sanding sheet.
To sand corners, edges and hard-to-reach areas accurately,
you can also work with the tips alone or with an edge of the
sanding plate.
The sanding sheet may heat up significantly when used to
sand specific points rather than entire surfaces. Reduce the
orbital stroke rate and contact pressure and allow the sand-
ing sheet to cool down at regular intervals.
Do not use a sanding sheet for other materials after it has
been used to work on metal.
Use only original Bosch sanding accessories.
Always connect a dust extraction system for sanding.
Scraping
Select a high orbital stroke rate level for scraping.
Work on a soft surface (e.g. wood) at a flat angle and with
low contact pressure. Failure to do so may cause the scraper
to cut into the surface underneath.

Maintenance and Servicing

Maintenance and cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Regularly clean Riff application tools (accessories) using a
wire brush.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by a
customer service centre that is authorised to repair Bosch
power tools.
