The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– 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)
Insert the dust extraction adapter (9) (accessory) into an ex-
traction hose (8) (accessory) until you hear it click into
place. Connect the dust extraction adapter (9) to the extrac-
tion outlet (6) on the power tool and the extraction hose (8)
to a vacuum cleaner (accessory).
You will find an overview of connecting to various dust ex-
tractors 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:
Application
Can be used to work on all materials including
wood, paint, filler, varnish, hard and softwood
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
Grit
40–180
Coarse 40
Medium 80, 120
