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
Choosing the Sanding Sheet
Select a sanding sheet with a grit suitable for how much material you want to remove. Bosch sanding sheets are suitable for
paint, wood and metal.
Use
Sanding down – Coarse sanding work with a
high material removal rate
(coarse sand-
ing)
– Removing old paint
Preparing – Light sanding
(intermediate
– Abrading surfaces for further
sanding)
processing later on
Fine sanding – Intermediate paint sanding
– Abrading flaws in the paintwork
Changing the Sanding Sheet
To remove the sanding sheet (4), lift it from the side and pull
it from the sanding pad (3).
Remove dirt and dust from the sanding pad (3), e.g. with a
paintbrush, before attaching a new sanding sheet.
The surface of the sanding pad (3) is fitted with a hook-and-
loop fastening, allowing sanding sheets with a hook-and-loop
backing to be secured quickly and easily.
Press the sanding sheet (4) firmly onto the underside of the
sanding pad (3).
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet (4) are aligned with the
drilled holes in the sanding pad (3).
Changing the Sanding Pad (see figure B)
Note: Replace damaged sanding pads (3) immediately.
Pull off the sanding sheet. Unscrew the four screws com-
pletely (9) and remove the sanding pad (3). Attach the new
sanding pad (3) and retighten the screws.

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.
Application
– Sanding down old paint, varnish and filler
– Removing thin paint
– Pre-sanding rough, unplaned surfaces
– Sanding uneven surfaces to make them
even
– Removing marks left by coarse sanding
– Repairing surfaces before applying paint or
varnish
– Removing fibres from the surface
– Fine sanding before staining
– Abrading primer before painting

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.
