Extended Sanding Plate, Rectangular, Thin
(GSS 230 A/GSS 230 AE) (see figure G)
Use of the rectangular, thin, extended sanding
plate 21 enables sanding at hard-to-reach loca-
tions and narrow interspaces, e. g. on window
and door sills, grooves or behind radiators or
water pipes.
To mount the rectangular, thin, extended sand-
ing plate 21, use the corresponding screws 23.
Extended Sanding Plate, Triangular
(GSS 230 A/GSS 230 AE) (see figure H)
Use of the extended triangular sanding plate 25
enables sanding 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 recommend-
ed to use the finish-sanding plate without velcro
backing. Due to its plane sanding plate surface,
optimum results are achieved, especially for fin-
ish sanding.
Auxiliary Handle
The auxiliary handle 1 enables convenient han-
dling and optimal distribution of power, espe-
cially at high removal rates.
Fasten the auxiliary handle 1 with screw 2 to the
casing.
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 4
and keep it pressed.
To lock the pressed On/Off switch 4, press the
lock-on button 5.
Bosch Power Tools
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 or-
bital stroke rate 3, you can preselect the re-
quired orbital stroke rate, even during opera-
tion.
The required stroke rate depends on the materi-
al and the working conditions and can be deter-
mined through practical testing.
Working Advice
Wait until the machine has come to a stand-
still 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 pres-
sure; this increases the working life of the sand-
ing sheets.
Intensifiying the sanding pressure does not lead
to an increase of the sanding capacity, but to in-
creased 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
Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
