– As far as possible, use a dust extraction 

system suitable for the material.

– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your 
country for the materials to be worked.

f

Prevent dust accumulation at the work-
place. 

Dusts can easily ignite.

Integrated Dust Extraction with Dust Box 
(see figures C – G)

Mount the dust box 

7

 onto the extraction outlet 

12

. Turn the dust box in such a manner that its 

recesses face against the tips on the extraction 
outlet and the dust box can be felt to engage.
The filling level of the dust box 

7

 can easily be 

checked through the transparent container.
To empty the dust box 

7

, pull it off toward the 

rear with a slight twisting motion.
Screw the filter element 

6

 on and pull it out of 

the dust box 

7

. Empty the dust box.

To loosen the dust, gently strike or tap the filter 
element 

6

 against a firm surface. Clean the la-

mellas of the filter element 

6

 with a soft brush.

Note: 

To ensure optimum dust extraction, 

empty the dust box 

7

 in good time and clean the 

filter element 

6

 at regular intervals.

When working vertical surfaces, hold the power 
tool in such a manner that the dust box 

7

 faces 

downward.

External Dust Extraction (see figure H)

Mount a vacuum hose 

13

 onto the extraction 

outlet 

12

. Mount the vacuum hose onto the ex-

traction outlet (as shown in the figure) in such a 
manner that the lateral openings on the extrac-
tion outlet remain free. This prevents the power 
tool from adhering to the workpiece during 
sanding and the surface quality of the work-
piece from being impaired.
Connect the vacuum hose 

13

 to a vacuum clean-

er (accessory). An overview for connecting to 
various vacuum cleaners can be found at the 
end of this manual.

The vacuum cleaner must be suitable for the 
material being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special 
vacuum cleaner.
When working vertical surfaces, hold the power 
tool in such a manner that the vacuum hose fac-
es downward.

Auxiliary Handle

The auxiliary handle 

1

 enables convenient han-

dling and optimal distribution of power, espe-
cially at high removal rates.
Fasten the auxiliary handle 

1

 with screw 

2

 to the 

casing.

Operation

Starting Operation

f

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, press the On/Off switch 

4

.

To 

lock

 the On/Off switch, keep it pressed and 

additionally push the lock-on button 

5

.

To 

switch off

 the machine, release the On/Off 

switch 

4

. When the On/Off switch 

4

 is locked, 

press it first and then release it.

Preselecting the Orbital Stroke Rate

With the thumbwheel for preselection of the or-
bital stroke rate 

3

, 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 deter-
mined through practical testing.
After longer periods of working at low stroke 
rate, allow the machine to cool down by running 
it for approx. 3 minutes at maximum stroke rate 
with no load.

1 – 2 

Low stroke rate

3 – 4 Medium 

stroke 

rate

5 – 6 

High stroke rate
