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 (2) 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.
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.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced
or the power tool switches off. At reduced speed, the power
tool will run again at full speed once the permitted battery
temperature is reached or the load is reduced. If it automat-
ically shuts down, switch the power tool off, allow the bat-
tery to cool down, then switch the power tool back on.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.

Maintenance and Service

Maintenance and Cleaning

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
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.
