Take care that no persons are endangered by flying
sparks. Remove combustible material from the vicini-
ty. When sanding metals, sparks are produced.
Caution, fire hazard! Avoid overheating of the sanded
material and the electro-tool. Always empty the dust
container before pauses in the work. For unfavourable
conditions such as flying sparks when sanding metals,
sanding dust in the dust bag, micro filter or paper sack (or
in the filter sack or filter of the wet/dry vacuum cleaner) can
self-ignite, especially when mixed with remainders of var-
nish, polyurethane or other chemical materials and when
the sanded work piece is hot after long periods of working.
6. REPLACING THE SANDING SHEET/
SANDING PLATE
Before any work on the machine itself, pull the mains plug.
Changing the Sanding Plate
Replace damaged sanding plates without delay. To re-
place the sanding plate 7, pull off the sanding sheet or po-
lishing tool.
When placing on the sanding plate, take care that the
teeth of the drive piece engage in the recesses of the
sanding plate.
Changing the Sanding Sheet
Lift the sanding sheet 5 at the edge and pull it off the san-
ding plate 7. Clean the sanding plate7 , if required.
Press the new sanding sheet 5 against the bottom of the
sanding plate. To ensure optimum dust extraction, the ho-
les of the sanding sheet must match with those of the san-
ding plate.
7. DUST/CHIP VACUUMING
External Dust Extraction with a Vacuum
Cleaner (Accessory pages)
Connect a vacuuming hose (accessory) directly to the
vacuuming adapter 3.
The vacuum cleaner must be suitable for the material to
be worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.

8. PUTTING INTO OPERATION

Switching On/Off
To switch on: Slide the on/off switch 2 forward and press
down until it latches.
To switch off: Press the on/off switch 2 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 (seeA pplication 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.

9. WORKING INSTRUCTIONS

Wait until the machine comes to a standstill before
putting it down.
Before any work on the machine itself, pull the mains plug.
Sanding Surfaces
Only flawless sanding sheets produce good sanding
performance and protects the machine.
Switch on the machine, place the complete sanding plate
on the surface to be worked and move the machine over
the work piece with moderate pressure.
Ensure uniform sanding pressure. Less sanding pressure
increases the sanding capacity and protects the machine
and the sanding tool.
The removal performance and the sanding pattern is
determined essentially by the choice of sanding sheet
(grain), the selected speed, the operating mode and the
application pressure.
Rough Sanding
Attach a sanding sheet with coarse grain
Apply only light pressure to the machine so that it runs at
high speed and high material removal is achieved.
Fine Sanding
Attach a sanding sheet with fine grain. By lightly varying
the application pressure or changing the speed setting, the
sanding plate speed can be reduced whereby the eccentric
movement is retained.
With moderate pressure, move the machine in a circular
pattern or alternately in lengthwise and crosswise directions
over the work piece.
Do not tilt the machine to avoid sanding through the work
piece (e.g. when sanding veneer).
After finishing the work, switch off the machine and lift
it from the work piece.
Polishing
For the polishing of weathered paint or buffing out of
scratches (e.g., Acrylic glass), the machine can be
equipped with appropriate tools such as a lamb's wool
bonnet, polishing felt or sponge (optional accessories).
When polishing with high speed, take care that the
polished surface does not become excessively warm.
For polishing, the vacuuming adapter 4 can be removed to
make the machine easier to handle and to prevent damage
to the work piece Apply polishing agent crosswise or in a
circular motion with a sponge and moderate pressure and
then allow to dry lightly.
Polish the partially dried polishing agent with crosswise or
circular motions using a lamb's wool polishing bonnet.
Cleaning the polishing tools.
Clean the polishing tools regularly to ensure good polishing
results.
It is recommended to wash the polishing tools with a mild
detergent and warm water (do not use paint thinning
agents).
