sanding sheet (7) between the rear clamping bracket
and the red roller on the clamp (5).
❺ Hold on to the sanding sheet so that it is tensioned, then
push the clamp (5) towards the sanding plate to lock in
the sanding sheet.
Unperforated sanding sheets, e.g. from rolls or bulk stock
sold by the metre, can be perforated using the punch (10)
for the purpose of dust extraction. To do this, fit the sanding
sheet on the power tool and push the tool down onto the
punch (see figure E).
To remove the sanding sheet (7), unlock the clamp (5) and
pull the sanding sheet out of its rear bracket. Press the re-
lease button (8) and completely remove the sanding sheet.
Selecting a sanding sheet
Different sanding sheets are available, depending on the ma-
terial you are working with and the required surface removal
rate:
For processing all wood and wood-based ma-
terials
For pre-sanding, e.g. of rough and un-
even beams and boards
For surface sanding and levelling of
slight irregularities
For finish-sanding and fine sanding of
hardwoods
For processing paint and lacquer layers or
primers such as fillers and bodyfillers
For sanding down paint
For sanding undercoats
For final sanding of primers prior to
painting
Changing the sanding plate (see figure F)
If necessary, the sanding plate (6) can be replaced.
Unscrew the four screws (11) completely and remove the
sanding plate (6). Fit the new sanding plate (6) and
retighten the screws.
Operation
Starting Operation
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
with 230 V can also be operated with 220 V.

Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching on/off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To switch on the power tool, press and hold the on/off
switch (2).
To lock the on/off switch (2) press and hold it while also
pushing the lock-on button (3).
To switch off the power tool, release the on/off switch (2).
If the on/off switch (2) is locked, press the switch first and
then release it.
Preselecting the orbital stroke rate
You can even preselect the orbital stroke rate during opera-
tion using the necessary orbital stroke rate preselection
thumbwheel (1).
Grit
The required orbital stroke rate is dependent on the material
40–240
and the work conditions and can be determined using prac-
tical tests.
Practical advice
Coarse 40, 60
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Medium 80, 100,
Always wait until the power tool has come to a com-
u
120
plete stop before placing it down.
The material removal rate when sanding is primarily determ-
Fine
180, 240
ined by the choice of sanding sheet and the preselected or-
bital stroke rate .
40–320
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.
Coarse 40, 60
Excessively increasing the contact pressure will not lead to
Medium 80, 100,
increased sanding performance, rather it will cause more
120
severe wear of the power tool and of the sanding sheet.
Fine
180, 240,
Do not use a sanding sheet for other materials after it has
320
been used to work on metal.
Use only original Bosch sanding accessories.
Maintenance and Servicing
