Replacing the Sanding Plate (see figure F)
The sanding plate 9 can be replaced, if required.
Unscrew the 6 screws 21 completely and remove the sanding
plate 9. Attach the new sanding plate 9 and tighten the screws
again.
Specialty Sanding Plates
You can replace the supplied sanding plate 9 with a specialty
sanding plate, which is available as an accessory.
The specialty sanding plate is attached in the same manner as
the one supplied.
Attach and remove the respective sanding sheets in the same
manner as when changing original sanding sheets.
Extended Sanding Plate, Rectangular, Thin
(GSS 230 A/GSS 230 AE) (see figure G)
Use of the rectangular, thin, extended sanding plate 22 ena-
bles sanding at hard-to-reach locations and narrow interspac-
es, e. g. on window and door sills, grooves or behind radiators
or water pipes.
To mount the rectangular, thin, extended sanding plate 22,
use the corresponding screws 24.
Extended Sanding Plate, Triangular
(GSS 230 A/GSS 230 AE) (see figure H)
Use of the extended triangular sanding plate 26 enables sand-
ing in edges and corners.
Finish-sanding Plate (without velcro backing)
(GSS 230 AE/GSS 280 AE) (see figure D)
When operating mainly with standard sanding sheets without
velcro backing, it is recommended to use the finish-sanding
plate without velcro backing. Due to its plane sanding plate
surface, optimum results are achieved, especially for finish
sanding.
Auxiliary Handle
The auxiliary handle 1 enables convenient handling and opti-
mal distribution of power, especially at high removal rates.
Fasten the auxiliary handle 1 with screw 2 to the casing.
Operation
Starting Operation
f 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, press the On/Off switch 4 and keep it
pressed.
To lock the pressed On/Off switch 4, press the lock-on button
5.
To switch off the machine, release the On/Off switch 4 or
when it is locked with the lock-on button 5, briefly press the
On/Off switch 4 and then release it.
Preselecting the Orbital Stroke Rate
(GSS 230 AE/GSS 280 AE)
With the thumbwheel for preselection of the orbital stroke
rate 3, 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.
Working Advice
f Wait until the machine has come to a standstill before
placing it down.
The removal capacity during sanding is mainly determined by
the selection of the sanding sheet as well as the preselected
orbital stroke rate (GSS 230 AE/GSS 280 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 increas-
es 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.
Maintenance and Service
Maintenance and Cleaning
f Before any work on the machine itself, pull the mains
plug.
f For safe and proper working, always keep the machine
and ventilation slots clean.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
