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.

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 or 180 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.
7 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.
