Apply the machine to the workpiece only when
switched on. Work with moderate feed and car-
ry out the sanding with parallel and overlapping
strokes. Sand in the direction of the grain; sand-
ing across the grain produces an uneven sand-
ing effect.
Particularly when sanding coats of varnish, sand
in the direction of the grain as the varnish could
melt and smear the surface of the workpiece
and the sanding belt. Therefore, work with dust
extraction.
A sanding belt used for sanding metal should
not be used for other materials.
Use only original Bosch sanding accessories.
Store sanding belts only hanging; avoid creas-
ing, as this makes the belts unusable.
The sanding frame (accessory) allows for uni-
form and controllable removal capacity when
surface grinding larger wooden surfaces.
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.
Remove adherent sanding dust with a brush.
Cleaning the Dust Passage (see figure B)
From time to time, remove the protection cover
10 and clean the dust passage 11 so that the
suction capacity remains at an optimum level.
Bosch Power Tools
Changing the Graphit Plate (Accessory)
(see figure C)
The graphite plate 12 (accessory) is screwed on-
to the guide plate 13 and enables an optimum
sanding pattern.
The graphite plate 12 is subject to wear, de-
pending on the intensity of usage. To change the
graphite plate 12, remove the sanding belt 2.
Unscrew the graphite plate 12 and replace it. Af-
ter mounting the sanding belt, adjust the belt
run as described in section "Changing the Sand-
ing Belt" on page 18.
If the machine should fail despite the care taken
in manufacturing 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 include the 10-digit article
number given on the type plate of the machine.
