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.

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

the power tool and the ventilation slots clean.
In order to avoid safety hazards, if the power supply cord

Regularly clean Riff application tools (accessories) using a
wire brush.
