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 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. 

Dusts can 

easily ignite.

Connecting the Dust Extraction (see figure A)

For sanding, always connect the dust extraction.

Remove the application tool/accessory when mounting the 
dust extraction 

17

 (accessory).

If required, assemble the parts of the dust extraction 

17

 as 

shown in the figure. Position the assembled dust extraction 
onto the machine via the tool holder 

9

. Turn the dust extrac-

tion in such a manner that the cams of the dust extraction en-
gage into the corresponding recesses on the housing. Fasten 
the dust extraction to the machine with the retaining clip 

15

as shown in the figure.

Pay attention that the felt ring 

14

 is undamaged and faces 

tightly against the sanding plate 

12

. Replace a damage felt 

ring immediately.

Depending on the machine model, place a vacuum hose 

18

(accessory) either directly onto the vacuum connection 

16

 or 

cut off the old hose end, screw the extraction adapter 

19

 (ac-

cessory) onto the hose end and insert it directly into the vac-
uum connection 

16

. Connect the vacuum hose 

18

 with a vac-

uum cleaner (accessory). An overview for the connection of 
various vacuum cleaners can be found at the end of these in-
structions.

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. 

Using other batteries can lead to injuries and pose a fire 
hazard.

Note: 

Use of batteries not suitable for the machine can lead to 

malfunctions of or cause damage to the power tool.

Insert the charged battery pack 

5

 from the rear into the base 

of the power tool. Press the battery pack completely into the 
base until the red stripe can no longer be seen and the battery 
pack is securely locked.

Switching On and Off

To 

start

 the machine, push the On/Off switch 

1

 forward so 

that the 

“I”

 is indicated on the switch.

To 

switch off

 the machine, push the On/Off switch 

1

 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 lithium-ion battery is protected against deep discharging 
by the “Electronic Cell Protection (ECP)”. When the battery is 
empty, the machine is switched off by means of a protective 
circuit: The inserted tool no longer rotates.

Note: 

If the machine should automatically switch off because 

of a discharged or overheated battery, make sure to set the 
machine’s On/Off switch 

1

 to off. Charge the battery and al-

low it to cool down before restarting the machine. Otherwise 
the battery can become damaged.

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.

Working Advice



Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport 
and storage, remove the battery from the power tool. 

There is danger of injury when unintentionally actuating 
the On/Off switch.



Wait until the machine has come to a standstill before 
placing it down. 

Note: 

Do not cover off the venting slots 

2

 of the machine while 

working, as this reduces the working life of the machine.

Operating Principle

Due to the oscillating drive the application tool/accessory 
oscillates up to 20 000 times per minute at 2.8 °. This allows 
for precise work in narrow spaces.

Work with low and uniform application 
pressure, otherwise, the working perfor-
mance will decline and the application tool 
can become blocked.

While working, move the machine back and 
forth, so that the application tool does not 
heat up excessively and become blocked.
