Slide the extraction adapter onto the outlet piece and take care that
the latching lever engages. For removal, press the latching lever in at
the rear and pull off the extraction adapter.
External Vacuuming
When sanding vertical surfaces, hold the machine so that the
extraction hose points downwards. 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.
4 SWITCHING ON/OFF
ON /OFF SWITCH
Depress to start and release to stop your tool.
LOCK-ON SWITCH
Depress on/off switch (2) then lock-on button (1), release on/off
switch first and lock-on button second. Your switch is now locked
on for continuous use. To switch off your sander just depress and
release the on/off switch.

AUXILIARY HANDLE (See Fig. D )
The auxiliary handle makes possible comfortable handling and
optimum force application, especially for high material removal. The
position of the auxiliary handle can be adjusted using winged screw.

SANDING PLATE BRAKE
An integrated sanding plate brake reduces the speed when running
at no load so that scoring is avoided when placing the machine on the
work piece. A continuously increasing no-load speed over the course
of time indicates that the sanding plate brake is worn and must be
replaced by an authorized customer service location.

SANDING SURFACES
Place the machine with the complete Sand paper on the surface to
be worked. Ensure uniform sanding pressure. Less sanding pressure
increases the sanding capacity and protects the machine and the
sanding tool. The removal capacity and the sanding pattern are
determined mainly by the selection of the Sand paper (grain size), the
speed of the sanding plate and the application pressure.
Rough Sanding
Attach a Sand paper with coarse grain. Apply only light sanding
pressure to achieve increased material removal.
Fine Sanding
Attach a Sand paper with fine grain. 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.
Application table
The following table should be used only as a recommendation.
The most suitable combination for the work to be performed is
best determined by practical trial.
