Dust/Chip Vacuuming
External Dust Extraction with a Vacuum
Cleaner
(Accessory pages)
Connect a vacuuming hose (accessory) directly to the
vacuuming adapter 4.
The vacuuming adapter 4 is made of
antistatic material. With the additional
use of an antistatic vacuuming hose
(accessory), the electrostatic charging
of the machine, which can occur while
sanding in rare cases, is prevented.
The vacuum cleaner must be suitable for the material
to be worked.
When vacuuming dry dust that is especially detrimen-
tal to health or carcinogenic, use a special vacuum
cleaner.

Putting into Operation

Ensure that the mains voltage is correct!
The voltage of the power source must agree with the
value given on the nameplate of the machine.
Machines designated for 230 V can also be operated
with 220 V.
Switching On/Off
To switch on: Slide the on/off switch 3 forward and
press down until it latches.
To switch off: Press the on/off switch 3 down at the
rear until it springs to the off position.
Speed Selection
Preselect the required speed with the thumbwheel 1
(also while running).
The Constant Electronics maintain the preselected
speed nearly constant also under load.
The required speed is dependent on the material and
can be determined by practical trials (see Application
Table).
After longer periods of working at low speed, allow the
machine to cool by running for approx. 3 minutes at
maximum speed with no load.

Selection of the Removal Performance
Two operating modes with different removal perform-
ances are available. To change the removal perform-
ance, press the unlocking button 12 and turn the op-
erating mode switch 11 until it can be heard to latch at
the symbol of the desired operating mode.
Do not change the operating mode while sand-
ing! The danger of injury exists.
Operating Mode 1 (Forced Drive)
This operating mode with high material removal is rec-
ommended for the working of very rough, insensitive
surfaces as well as for buffing. As a result of the forced
drive, the sanding plate has constant eccentricity and
rotational movement.
Operating Mode 2 (Free Running)
This operating mode is recommended for the handling
of sensitive surfaces 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 varying the applica-
tion pressure, the material removal can also be regu-
lated.

Working Instructions

Wait until the machine comes to a standstill
I
before putting it down.
Before any work on the machine itself, pull the
I
mains plug.
Removing the Vacuuming Adapter
For working without dust extraction (e.g. polishing),
the vacuuming adapter 4 can be removed. For this
purpose, unscrew the screw 2 with a L-type Allen key
7 and pull the vacuuming adapter 4 from the housing.
To mount the vacuuming adapter, proceed in the re-
verse order. Take care that the vacuuming adapter 4
is properly seated in the housing opening.
Auxiliary Handle
The auxiliary handle 5 can be screwed into the thread-
ed hole 13 optionally on the right or the left.
