Then remove the worn sanding belt and
fi t a new one. Fit the sanding belt in the
reverse order compared to removal and
adjust it until it runs evenly.
Tightening and adjusting the
sanding belt
You can tighten and adjust the sanding belt
using the guide roller (9), the adjustment
spring (10) and adjustment knob (8). Undo
the adjustment spring (10), rotate the
sanding belt by hand towards the drive
pulley (11), and adjust the sanding belt
using the adjustment knob (8) so that it
runs in the centre of the drive pulley.
Operation
The sanding belt and sanding disc on the
machine are designed for general sanding
work. Both sanding belt and sanding disc
are ideal for sanding materials such as
metal, wood or plastic. You can achieve
the best results for surface sanding by
holding the workpiece securely, but
without pressing it down hard against the
sandpaper. Move the workpiece forward
and back on the sandpaper so that the
sandpaper wears evenly and the workpiece
gains a smooth surface.
Use the sanding stop (see fi g. 2) to rest
against the workpiece. If the workpiece is
longer than the sanding surface, you must
remove the sanding stop so you can use the
entire sanding belt.
The sanding belt is ideal for planing wood.
As the sanding belt has been secured using
a non-hardening adhesive, you can easily
fi t a new sanding belt with a diff erent grain
size. You can undertake drum sanding at
both ends of the sanding belt (see the
example in fi g. 5).
You can undertake fl exible belt sanding
on the reverse of the sanding belt using
the sander in a vertical position. Slacken
the sanding belt so that it can mould to
the shape of the workpiece. The quality of
the work depends on both the grain size
of the sandpaper and the manner in which
the workpiece is handled. You can achieve
optimum results if you start with coarse
sandpaper and then slowly work towards
fi ner types. The sandpaper is available in
three basic grain sizes: fi ne, medium and
coarse. The sanding belt and disc fi tted on
delivery are both medium.
It is often a good idea to use the sander in
a vertical position (see under “Vertical and
horizontal sanding”). When using the sander
in the vertical position, the workpiece
normally rests on the bench and not on the
sanding belt.
