Choice of Application Tool/Abrasive
Depending on the material to be worked and the required rate
of material removal, different application tools/abrasives are
available:
– Rollers with permanent abrasive
– Rollers for use with changeable sanding belts
– Deflection rollers for use with sanding belts
For dry sanding and pre-sanding coarse
For structuring and for smooth-
ing out minor unevenness

Operation
Starting Operation
Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate
of the machine.
Switching On and Off
To start the machine, press the On/Off switch 4 and keep it
pressed.
To lock the pressed On/Off switch 4, push the On/Off switch
4 further toward the front.
To switch off the power tool, release the On/Off switch 4, or
when it is locked, briefly press the On/Off switch 4 and then
release it.
To save energy, only switch the power tool on when using it.
Preselecting the Speed
Operate with a speed adapted to the application, in or-
der to prevent damage to the material.
The required speed can be preselected with the thumbwheel
3 (also while running).
Bosch Power Tools
The required speed depends on the material and the working
conditions and can be determined through practical testing.
When using fleece, do not work with a higher setting
Working Advice
When sanding, the removal capacity and the surface quality
are mainly determined by the abrasive selection as well as
through the preselected speed.
Work with the lowest possible sanding pressure in order to in-
crease the service life of the abrasive. Excessively increasing
the sanding pressure does not lead to a higher sanding capac-
ity, but to more wear of the power tool and the abrasive.
Work with moderate feed and perform the sanding parallel
and overlapping with respect to the sanding paths.
To achieve a perfect surface, do not skip more than one grain
size when selecting the abrasive.
Use only original Bosch sanding accessories.
Only proper abrasives achieve good sanding capacity and
give the power tool longer service life.
Do not clamp power tools in the saw stand. Clamped
