Instruction & User Manual

Sanding Surfaces

m

Place the machine flat on the workpiece, 
ensuring the entire anding disc makes even 
contact.

m

Power on the sander.

m

Apply uniform sanding pressure.

m

Adjust your pressure to suit the work as 
required.

Less sanding pressure increases the sanding 
capacity and protects the machine and the 
sanding paper.

NOTE

The removal capacity and the sanding pat-
tern are determined mainly by the selection 
of the Sand paper (grade), the speed of the 
sanding pad and the application pressure.

NOTE

Rough Sanding

m

Attach a sand paper with coarse grain.

m

Apply only light sanding pressure to achieve 
increased material removal.

For faster material removal, do not increase 
pressure on the tool, instead use a coarser 
sanding sheet.

NOTE

Fine Sanding

m

Attach a sand paper with fine grain.

m

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 during operation. 
This will apply uneven pressure, and may 
cause damage to the work piece (e.g. when 
sanding veneer).

NOTE

To avoid marring the finished surface, switch 
off the machine, and only lift it from the 
workpiece when it has come to a stop.

NOTE

Orbital Sanding

m

Guide your sander parallel to the working 
surface and move it in circles or in a cross 
pattern.

m

The speed of the orbital motion of the 
sanding pad is reduced as applied pressure 
increases.

Selecting The Right Grade Of 
Sandpaper

m

Use coarse grits to sand down rough 
finishes, medium grit to smooth the work 
and fine grit to finish off.

m

The higher the grade number, the finer the 
grit.

m

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.

m

If you use a fine grade for rough surfaces the 
sandpaper will clog and need changing more 
frequently.

The correct grade for your application will 
depend on sanding speed, material and pres-
sure applied. Always test on a scrap piece of 
material if possible.
