Sanding Sheets without Velcro Backing
(see figures B–D)
Press the release button 8 and keep it depressed.
Guide the sanding sheet 7 to the stop under the
opened front clamping bracket 9 and let go of the
release button 8 again. Pay attention that the sand-
ing sheet is clamped centrally.
Press the sanding sheet clamp 5 inward and pivot
it to the stop.
Fold the sanding sheet 7 firmly around the sanding
plate. Guide the other end of the sanding sheet 7
between the rear clamping bracket and the red
roller on the clamping bracket 5.
Hold the sanding sheet tensely and press the
clamping bracket 5 toward the sanding plate to
lock the sanding sheet.
Sanding sheets without holes, e. g. from rolls or by the
meter, can be punctured with the perforating tool 10 for
use with dust extraction. For this, press the machine
with the mounted sanding sheet onto the perforating
tool (see figure E).
To remove the sanding sheet 7, loosen the clamping
bracket 5 and pull out the sanding sheet from the rear
holding fixture. Press the release button 8 and com-
pletely remove the sanding sheet.
Selecting the Sanding Sheet
Depending on the material to be worked and the
required rate of material removal, different sanding
sheets are available:
For the working of all
wooden materials
For coarse-sanding, e. g. of
rough, unplaned beams and
boards
For face sanding and planing
small irregularities
For finish and fine sanding of
hard woods
For the working of
paint/enamel coats or
primers and fillers
For sanding off paint
For sanding primer
For final sanding of primers
before coating

sanding plate 6. Attach the new sanding plate 6 and
tighten the screws again.
Operation

Starting Operation

Observe correct mains voltage! The voltage of the
power 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, press the On/Off switch 2 and
keep it depressed.
To lock the pressed On/Off switch 2, press the lock-
on button 3.
To switch off the machine, release the On/Off switch
2 or when it is locked with the lock-on button 3, briefly
press the On/Off switch 2 and then release it.
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital
stroke rate 1, you can preselect the required orbital
stroke rate, even during operation.
The required stroke rate depends on the material and
the working conditions and can be determined through
practical testing.
Operating Instructions
B Wait until the machine has come to a stand-
still before placing it down.
The removal capacity during sanding is mainly deter-
mined by the selection of the sanding sheet as well as
the preselected orbital stroke rate.
Only flawless sanding sheets achieve good sanding
capacity and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this
increases the working life of the sanding sheets.
Intensifiying the sanding pressure does not lead to an
increase 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.
