3. OPERATING ThE ON/OFF SwITCh (See E)
To start your sander, depress the protective
cover over the switch at the position marked "I" .
To stop your sander, depress the protective
cover at the position marked "0" .
4. hAND GRIP AREA (See F, G)
Your sander is designed to be held either
around the main housings, or by the top of the
main housing. When sanding for long periods
at a time, it is recommended you periodically
alternate between the two holding positions.
5. 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 workpiece.
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 workpiece.
6. ORBITAL SANDING
Guide your sander parallel to the working
surface and move it in circles or in a cross
pattern. Do not tilt the tool in order to avoid
deep unwanted sanding marks. The amount of
material removed is determined by the speed
of the sanding disc and the grit size used. The
speed of the sanding disc diminishes relative
to the pressure applied to the tool. For faster
removal, do not increase pressure on the tool,
but use a coarser grit size.

7. SELECTING ThE RIGhT GRADE OF
SANDPAPER
— Different grades of sanding paper can be
purchased from good DIY shops. Available
grades are Coarse, Medium and Fine.
— Use coarse grits to sand down rough
finishes, medium grit to smooth the work
and fine grit to finish off.
— The higher the grade number, the finer the
grit. For rough work start with a low grade
of grit. (e.g. 60 grit) and change to a higher,
finer grade (e.g. 120 grit) for finishing. If
you use a fine grade for rough surfaces it
will soon clog and need changing.
— It is best to make a trial run on a scrap
piece of material to determine the optimum
grades of sandpaper for a particular job.
8. 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.
WORKING HINTS FOR YOUR
SANDER
If your power tool becomes too hot, especially
when used at low speed, set the speed to
maximum and run it with no load for 2-3
minutes to cool the motor. Avoid prolonged
usage at very low speeds. Always use sand
paper that is suitable for the material you want
to sand.
Always ensure the work-piece is firmly held or
clamped to prevent movement.
Any movement of the material may affect the
quality of the sanding finish.
Start your sander before sanding and turn it
off only after you stop sanding. For the best
results, sand wood in the direction of the
grain.
Do not start sanding without having the
sandpaper fitted.
Do not allow the sand paper to wear away
