Selecting the Sanding Sheet
Depending on the material to be worked and the required rate of material removal, different sanding sheets are available:
Sanding disc Material
– All wooden materials
(e.g., hardwood, soft-
wood, chipboard, build-
ing board)
– Metal materials
Red quality
– Paint
– Varnish
– Filling compound
– Filler
White quality

Dust/Chip Extraction

 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
Connecting the Dust Extraction
The dust extraction 17 is intended only when working with the
sanding plate 10; it is not of use in combination with other
application tools.
For sanding, always connect the dust extraction.
To mount the dust extraction 17 (accessory), remove the
application tool and the depth stop 12.
Slide the dust extraction 17 all the way over the tool holder 7
onto the collar of the power tool. Turn the dust extraction to
the required position (not directly under the power tool).
Press shut the clamping lever 18 to fix the dust extraction.
Plug the tool sleeve of the vacuum hose 15 onto the vacuum
connection 16. Connect the vacuum hose 15 to a vacuum
cleaner (accessory).
An overview for connecting to various vacuum cleaners can be
found on the graphics page.
Bosch Power Tools
Application
For coarse-sanding, e.g. of rough, unplaned beams
and boards
For face sanding and planing small irregularities
For finish and fine sanding of wood
For sanding off paint
For sanding primer (e.g., for removing brush dashes,
drops of paint and paint run)
For final sanding of primers before coating
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Operation

Starting Operation

 Observe the mains voltage! The voltage of the power
source must correspond with the data on the type plate of
the machine.
Switching On and Off
To start the machine, push the On/Off switch 2 forward so
that the "I" is indicated on the switch.
The electronic soft starting feature limits the torque upon
switching on and increases the working life of the motor.
The constant electronic control keeps the stroke rate almost
constant under no-load or load conditions and ensures a uni-
form working performance.
To switch off the machine, push the On/Off switch 2 toward
the rear so that the "0" is indicated on the switch.
To save energy, only switch the power tool on when using it.
The 180° light band improves visibility in the immediate work
area. It is automatically switched on and off with the power tool.
 Do not look directly into the work area illumination –
your sight can be temporarily degraded!
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital stroke
rate 4, you can preselect the required orbital stroke rate, even
during operation.
The required stroke rate depends on the material and the
working conditions and can be determined through practical
testing.
