– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Self-generated dust extraction with dust box (see figures
A1–A4)
Place the dust box (2) onto the extraction outlet (6) until it
clicks into place.
To empty the dust box (2), pull the dust box downwards.
Before opening the dust box (2), knock the dust box against
a firm surface as shown in the figure to loosen the dust from
the filter element.
Holding the dust box (2) firmly, flap the filter element (7)
upwards out of the way and empty the dust box. Use a soft
brush to clean the flaps of the filter element (7).
External dust extraction (see figure B)
Fit a dust extraction hose (8) onto the extraction outlet (6).
Connect the dust extraction hose (8) to an extractor. You
will find an overview of connecting to various dust extractors
at the end of these operating instructions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Changing the sanding sheet (see figure C)
Remove dirt and dust from the sanding plate (3), e.g. with a
brush, before attaching a new sanding sheet.
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet are aligned with the
drilled holes in the sanding plate.
The sanding plate (3) is fitted with a hook-and-loop fasten-
ing, allowing sanding sheets with a similar backing to be se-
cured quickly and easily.
Tap the hook-and-loop fastening of the sanding plate (3) be-
fore fitting the sanding sheet (4) to facilitate maximum adhe-
sion.
The power tool is equipped with two sanding sheets. De-
pending on their state of wear, these can also be changed in-
dividually.
Only use the power tool when both sanding sheets are
u
fitted.
Only use sanding sheets with the same grit.
u
Position the sanding sheet (4) so that it is flush with one a
side of the sanding plate (3), then place the sanding sheet
on the sanding plate and press it on firmly.
To remove the sanding sheet (4), take hold of it by an edge
and pull it away from the sanding plate (3).
You can use the Bosch delta sander sanding sheets.

Sanding accessories such as fleece/polishing felt are at-
tached to the sanding plate in the same way.
Choosing the sanding sheet
Different sanding sheets are available, depending on the ma-
terial you are working with and the required surface removal
rate:
Can be used to work on all materials including
wood, paint, filler, varnish, hard and soft wood
as well as chipboard and metal.
For pre-sanding, e.g. of rough and un-
even beams and boards
For surface sanding and levelling of
slight irregularities
For finish-sanding and fine sanding of
hardwoods
For any finishing work, such as polishing (metal and stone in
particular), use fleece/polishing felt.
Different types of fleece and polishing felts should be used
depending on the surface finish required on the workpiece.
Operation

Starting Operation

Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
230 V can also be operated at 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching on/off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To start the power tool, push the on/off switch (1) down-
wards and into position "1".
To switch off the power tool, push the on/off switch (1) up-
wards and into the position "0".

Practical advice

Pull the plug out of the socket before carrying out any
u
work on the power tool.
Always wait until the power tool has come to a com-
u
plete stop before placing it down.
The material removal rate when sanding is primarily determ-
ined by the choice of sanding sheet.
Only immaculate sanding sheets achieve good sanding per-
formance and make the power tool last longer.
Be sure to apply consistent contact pressure in order to in-
crease the lifetime of the sanding sheets.
Excessively increasing the contact pressure will not lead to
increased sanding performance, rather it will cause more
severe wear of the power tool and of the sanding sheet.
