Changing the sanding sheet (see figure A)
To remove the sanding sheet (6), 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 (6) firmly onto the underside of the
sanding pad (3).
To ensure optimum dust extraction, make sure that the
punched holes in the sanding sheet (6) are aligned with the
drilled holes in the sanding pad (3).
Selection of the Sanding Pad
The power tool can be fitted with sanding pad of various
hardnesses, depending on the application:
– Soft sanding pad: Suitable for sensitive sanding even on
curved surfaces
– Medium-hard sanding pad: Suitable for all sanding work,
universal application
– Hard sanding pad: Suitable for heavy sanding on flat sur-
faces
Changing the Sanding Pad (see figure B)
Note: Replace damaged sanding pads (3) immediately.
Pull off the sanding sheet. Unscrew the four screws
completely (7) and remove the sanding pad (3). Attach the
new sanding pad (3) and retighten the screws.
Note: When attaching the sanding pad, make sure that the
teeth of the catch mate with the recesses in the sanding pad.
Note: Damaged sanding pad holders (8) must only be re-
placed by an after-sales service centre authorised to work
with Bosch power tools.
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.
Bosch Power Tools
Self-generated dust extraction with dust bag
(see figures C–E)
Place and move the complete dust bag (4) onto the extrac-
tion outlet (9) until it lines up precisely with the power tool.
To empty the dust bag, pull the complete dust bag (4) away
from the extraction outlet (9).
Note: Empty the dust bag (4) in good time to ensure op-
timum dust extraction.
When working vertical surfaces, hold the power tool in such
a manner that the dust bag (4) faces downward.
External dust extraction (see figure F)
Fit a dust extraction hose (10) onto the extraction outlet (9).
Connect the dust extraction hose (10) 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.
When working on vertical surfaces, hold the power tool with
the dust extraction hose facing downwards.
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.
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 switch on the power tool, tilt the on/off switch (1) to-
ward the right to the "I" position.
To switch off the power tool, tilt the on/off switch (1) to-
ward the left to the "O" position.
Preselecting the orbital stroke rate
You can even preselect the orbital stroke rate during opera-
tion using the necessary orbital stroke rate preselection
thumbwheel (2).
1–2
Low orbital stroke rate
3–4
Medium orbital stroke rate
5–6
High orbital stroke rate
The required orbital stroke rate is dependent on the material
and the work conditions and can be determined using prac-
tical tests.
After working at a low orbital stoke rate for an extended
period, you should operate the power tool at the maximum
orbital stroke rate for approximately three minutes without
load to cool it down.
