External Dust Extraction
Connect the vacuum hose (accessory) directly
at the extraction outlet piece 10.
Note: The extraction outlet piece 10 is made of
anti-static material. When additionally using an
anti-static vacuum hose (accessory), electro-
static charging of the machine, which can occur
in rare cases while sanding, is prevented.
For applications without dust extraction (e. g.,
polishing), the extraction outlet piece 10 can be
removed. For this, unscrew the screw 12 with
the Allen key 7 (accessory) and remove the ex-
traction outlet piece 10 from the housing.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.

Auxiliary Handle

The auxiliary handle 9 enables convenient han-
dling and optimal distribution of power, espe-
cially at high removal rates.
Screw the auxiliary handle 9 either at the right
or the left side of the housing into the thread 1.
Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the power tool, push the On/Off switch
11 forwards.
To lock the On/Off switch 11, press the On/Off
switch 11 down at the front until it latches.
To switch off the power tool, release the On/Off
switch 11 or, if it is locked, briefly push down
the back of the On/Off switch 11 and then re-
lease it.

Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the or-
bital stroke rate 13, you can preselect the re-
quired orbital stroke rate, even during opera-
tion.
1 – 2 Low stroke rate
3 – 4 Medium stroke rate
5 – 6 High stroke rate
The required stroke rate depends on the materi-
al and the working conditions and can be deter-
mined through practical testing.
The constant electronic control keeps the
stroke rate almost constant under no-load or
load conditions and ensures a uniform working
performance.
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.
Selection of Removal Rate
Two operating modes with different removal
rates are available. To change the removal rate,
press the unlocking button 2 and turn the mode
selector switch 3 until it can be heard to latch at
the symbol of the requested operating mode.
Do not change the operating mode while
sanding! Danger of injury.
Operating Mode 1 (Forced Drive)
This operating mode with high ma-
terial removal is recommended for
working very rough, insensitive surfaces as well
as for buffing. As a result of the forced drive, the
sanding plate has constant eccentricity and ro-
tational movement.
Operating Mode 2 (Free Running)
This operating mode is recom-
mended for handling sensitive sur-
faces as well as for fine polishing. As a result of
the free running sanding plate, an application-
pressure dependent rotational movement at
constant eccentric motion is achieved. By vary-
ing the application pressure, the material re-
moval can also be regulated.
