Replacing the Sanding Sheet/
Sanding Plate
Before any work on the machine itself, pull the
s
mains plug.
Selecting the Sanding Sheet
Depending on the material to be worked and the de-
sired material removal, various sanding sheet qualities
are to be used:
For the working of all wooden materials.
For the working of all wooden materials as well as var-
ious metallic materials.
For the working of paint/enamel coats or primers and
fillers.
For the working of extremely hard materials such as
stone, marble, granite, ceramic or glass.
For the working of polymer materials such as Corian
®
and Variocor as well as the working of Plexiglas.
Changing the Sanding Sheet
Lift the sanding sheet 4 at the edge and pull it off the
sanding plate 3. Blow out the sanding plate 3 as nec-
essary.
Press the new sanding sheet 4 against the bottom of
the sanding plate. To ensure optimum dust extraction,
the holes of the sanding sheet must match with those
of the sanding plate.
Changing the Sanding Plate (see Fig.
Replace damaged sanding plates without delay.
Use only the Bosch accessory kit (No. 2 608 601 175)
intended for this purpose:
– Remove the sanding sheet 4.
– To remove the sanding plate, unscrew the four
Torx screws 8 with the L-type Torx key 9 and take
off the sanding plate.
– Attach the new sanding plate and screw in the
four Torx screws 8 tightly.
Damaged backing plates should be changed
only by a specialist.

Dust/Chip Vacuuming
Dust produced while working can be detrimental to
s
health, inflammable or explosive. Suitable protec-
tion measures are required.
Examples: Some dusts are considered to be carci-
nogenic. Use suitable dust/chip extraction and
wear a dust protection mask.
Light metal dust can burn or explode. Always keep
s
the work place clean since material mixtures are
especially dangerous.
Caution, fire hazard!
For unfavourable conditions such as fly-
ing sparks when sanding metals, sanding
dust in the dust bag, micro filter or paper
sack (or in the filter sack or filter of the
wet/dry vacuum cleaner) can self-ignite,
especially when mixed with remainders
of varnish, polyurethane or other chemi-
cal materials and when the sanded work
piece is hot after long periods of working.
Avoid overheating the object being sand-
ed as well as the machine and always
empty the dust container before pauses
in the work.
Internal Vacuuming with Dust Box
(see Fig.
Attaching the dust box
®
Slide the dust box 2 onto the outlet piece 5 until it
latches.
Emptying the dust box
Press the latching levers 6 and pull off the dust box 2.
Before opening the dust box 2, it is recommended that
the dust be loosened from the filter element by tapping
on a firm surface.
Open the dust box by swinging the filter element (mi-
cro-filtersystem) 7 upward and empty the dust box.
Clean the fins of the filter element with a soft brush.
External Vacuuming (see Fig.
)
B
(Accessory pages)
Slide the extraction adapter 10 onto the outlet piece 5
and take care that the latching levers 6 latch. To re-
move, press the latching levers together at the rear
and pull off the extraction adapter 10.
When sanding vertical surfaces, hold the machine so
that the extraction hose points downwards.
The vacuum cleaner must be suitable for the material
to be worked.
When vacuuming dry dust that is especially detrimen-
tal to health or carcinogenic, use a special vacuum
cleaner.
