Sanding Sheets without Velcro Backing
(PSS 190 AC/PSS 200 AC/PSS 250 A/
PSS 250 AE) (see figure B)
Lightly lift and unlatch the sanding-sheet clamp 4.
Guide the sanding sheet 6 under the opened rear sand-
ing-sheet clamp 4 to the stop and clamp the sanding
sheet by reinserting the sanding-sheet clamp 4.
Fold the sanding sheet 6 firmly around the sanding
plate. Guide the other end of the sanding sheet 6 under
the front sanding-sheet clamp 4 and clamp the sanding
sheet by reinserting the sanding-sheet clamp 4.
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 6, unlatch the sanding-
sheet clamp 4 and pull out 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:
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, push the On/Off switch 2
towards the front to “I”.
To switch off the machine, push the On/Off switch 2
towards the rear to “0”.
Preselecting the Orbital Stroke Rate
(PSS 250 AE)
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 (PSS 250 AE).
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.
