Operation
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
To start the machine, tilt the On/Off switch 1 to position "I".
To switch off the machine, tilt the On/Off switch 1 to position
"0".
To save energy, only switch the power tool on when using it.
Sanding Plate Brake
An integrated sanding plate brake reduces the stroke rate
when running at no-load so that scoring is prevented when
placing the machine onto the workpiece.
If the no-load stroke rate continuously increases over the
course of time, then the sanding plate is damaged and must
be replaced or the sanding plate brake is worn. A worn sand-
ing plate brake must be replaced by an authorised after-sales
service agent for Bosch power tools.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
 Wait until the machine has come to a standstill before
placing it down.
Sanding Surfaces
Switch the machine on, place it with the complete sanding
surface on the surface to be worked and move the machine
with moderate pressure over the workpiece.
The removal capacity and the sanding pattern are mainly de-
termined by the selection of the sanding sheet and the ap-
plied 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 in-
creases 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.
A sanding sheet that has been used for metal should not be
used for other materials.
Use only original Bosch sanding accessories.
Rough Sanding
Attach a sanding sheet with coarse grain.
Apply only light pressure to the machine so that it runs at a
higher stroke rate and high material removal is achieved.
Fine Sanding
Attach a sanding sheet with fine grain.
By lightly varying the application pressure, the sanding plate
stroke rate can be reduced whereby the orbital action is main-
tained.
With moderate pressure, move the machine in a circular pat-
tern or alternately in lengthwise and crosswise directions

over the workpiece. Do not tilt the machine to avoid sanding
through the workpiece (e.g. when sanding veneer).
After finishing the working procedure, switch the power tool
off.
