Dust/Chip Extraction
 Dusts 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 dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble 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. Dusts can
easily ignite.
Integrated Dust Extraction with Dust Box
(see figures D1 – D4)
Attach the dust box 1 onto the extraction outlet 13 until it
latches.
To empty the dust box 1, pull off the dust box downward.
Before opening the dust box 1, it is recommended to loosen
the dust from the filter element by gently striking it against a
firm support (as shown in the figure).
Grasp the dust box 1 by the recessed grip, fold the filter ele-
ment 14 upward and empty the dust box. Clean the thin
plates of the filter element 14 with a soft brush.
External Dust Extraction (see figure E)
Slide the extraction adapter 15 onto the outlet piece 13. En-
sure that the latching levers of the extraction adapter engage.
The extraction adapter 15 accepts a vacuum hose with a di-
ameter of 19 mm.
An overview for connecting to different vacuum cleaners can
be found at the end of these operating instructions.
For removal of the extraction adapter 15, press the latching
levers together at the rear and pull the extraction adapter off.
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
Inserting the battery
 Use only original Bosch lithium ion batteries with the
voltage listed on the nameplate of your power tool. Us-
ing other batteries can lead to injuries and pose a fire haz-
ard.
1 609 92A 1X0 | (2.12.15)
Switching On and Off
To start the machine, tilt the On/Off switch 7 toward the right
to the "I" position.
To switch off the machine, tilt the On/Off switch 7 toward the
left to the "0" position.
Battery Charge-control Indication (see figure A)
The three green LEDs of the battery charge-control indicator
9 indicate the charge condition of the battery 10. For safety
reasons, it is only possible to check the status of the charge
condition when the machine is at a standstill.
Press button 8 to indicate the charge condition. This is also
possible when the battery 10 is removed.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
When no LED lights up after pushing button 8, then the bat-
tery is defective and must be replaced.
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject
to overload. When the load is too high or the allowable battery
temperature of 65 °C is exceeded, the electronic control
switches off the power tool until the temperature is in the op-
timum temperature range again.
Working Advice
 Wait until the machine has come to a standstill before
placing it down.
The removal capacity during sanding is mainly determined by
the selection of the sanding sheet.
Only flawless sanding sheets achieve good sanding capacity
and extend the service life of the machine.
Pay attention to apply uniform sanding pressure; this increas-
es the working life of the sanding sheets.
Intensifiying the sanding pressure does not lead to an in-
crease of the sanding capacity, but to increased wear of the
machine and the sanding sheet.
A sanding sheet that has been used for metal should not be
used for other materials.
Use only original Bosch sanding accessories.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
0 °C and 50 °C. As an example, do not leave the battery in the
car in summer.
Occasionally clean the venting slots of the battery using a soft,
clean and dry brush.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
