Use of suction (D)
Dust is extracted from the work surface using an
adapter and a connected vacuum cleaner.
Place the adapter (3) on the socket.
Attach the hose of your vacuum cleaner to the
adapter (3).
On and off (E)
You can turn on the vibrating sander by pressing and
holding the switch (1).
You can turn off the sander by releasing the switch
(1).
Switch the sander to continuous operation by press-
ing and holding the switch (1), simultaneously press
the locking button (2), then release the switch.
Press and release the switch (1) to switch off the
sander from continuous operation.
Use
Always hold the sander firmly in your hand. Always
place it lightly on the surface you want to sand.
Attention - the first contact with the sanded material
can cause the sandpaper to „throw".
It is recommended to use circular movements when
working.
Check the sandpaper regularly and replace it when
worn.
If you need to process larger irregularities on the
material, it is recommended to work with sandpapers
of different grain sizes. 60 grit is recommended for
rough sanding, 80 grit is recommended for normal
medium rough sanding and 120 grit for fine finishing.
Surface treatment by sanding
The sandpaper pad moves in small circular orbits.
Therefore, the grains gradually cut in all directions.
Since the motion is circular, it doesn't matter how you
hold or move the sander, and it's rarely necessary to
apply extra pressure to the tool. The basic principle
when sanding is to use a suitable sandpaper that
will smooth out the unevenness on the surface. If
you use the if the paper is rough, the surface will not
be smoothed, but on the contrary will become even
rougher. Sandpaper that is too fine will remove exist-
ing irregularities very slowly or not at all. The first
sanding on some materials may require a coarser
sandpaper, while finer surfaces will require a medium
grit sandpaper. When in doubt, start with a finer
paper. If the results are poor, use a coarser paper,
but be sure to change back to a finer paper if coarser
lines start to appear. Be careful not to sand the edges
and veneer material, especially with thicker paper. An
old well-known trick to create a super smooth surface
is to „increase the grain". Wet the already sanded
surface with a wet cloth or sponge and let it dry com-
pletely. Due to the water, some wood fibers will swell
more than others, making the surface look rougher
than before. Sand it with fine paper, remove raised
particles. The result will be a nice smooth surface.
However, DO NOT use this method on veneered sur-
faces as moisture could be released into the veneer.
Decorating
Before removing the paint or varnish of the doors,
window frames, trims, etc., first check whether the
existing finish is in bad condition or not. We can call
the condition bad if there are cracks or flakes on the
surface to such an extent that they could be easily
removed with a wire brush or scraper. If the old finish
is firmly in place, there is no reason to remove it. Sim-
ply sand it with sandpaper to sufficiently remove any
surface imperfections. This will prepare the „base" for
the new coating. Start by using coarse sandpaper to
break up the hard surface of the old paint, then use
finer sandpaper to prepare the surface for the base
coat. Make sure that you have removed all defects of
the old coating. Old stained areas can be removed
very easily by very gently tilting the sander to the
edge of the pressure plate and with a gentle sanding
motion, concentrate the action of the sander on the
thicker coating until it aligns with the falcon area. If
most of the old paint is sound, but there are one or
two spots of bad paint, completely remove the bad
parts with very coarse sandpaper, and then level the
surrounding healthy paint so that it blends with the
soda-covered parts. If the entire surface to be painted
