Notes On Sanding Speed; Working With The Angle Stop (Fig. 8); Adhering Or Replacing The Sanding Discs (Fig. 9) - Proxxon TSG 250/E Mode D'emploi

For good sanding results, please note the fol-
lowing points:
Do not overload the device!
First and foremost, the disc sander is a machine
for sanding accurate angles. Cutting your work
piece very accurately beforehand will make your
desired machining easier and faster while
requiring less sanding discs.
The sanding disc rotates anticlockwise. It is
therefore advisable to sand using the left half of
the work table.
1. If you will be sanding mitres, adjust the
required sanding table angle beforehand, as
described earlier
2. Insert the mains plug
3. Use switch 2 (Fig. 1) to activate the device
4. Set the required rotational speed at the rota-
tional speed regulating knob (Pos. 1, Fig. 1)
Only use perfect sanding discs. Replace worn
out sanding discs in time.

7.1 Notes on sanding speed

The sanding speed of your TSG 250/E is infi-
nitely adjustable from approx. 250 - 750 m/min.
This enables you to optimally adjust to different
material features. Please also note that the cir-
cumferential speed of the sanding disc is great-
est along the outside and decreases towards
the centre (see Fig. 7).
General recommendations on selecting the
sanding speed are difficult; it is best you experi-
ment to find out the correct sanding speed for
„your" material or work piece.
Empirically, non-ferrous metals and plastic
require less sanding speeds than soft and hard
woods; the same also applies to ceramics and
glass.
In conclusion: Recommendations, as said, are
difficult: the right speed depends on the mate-
rial, contact pressure or abrasive wear and the
grit of the sanding discs.
Note:
Caution!

7.2 Working with the angle stop (Fig. 8):

If you will be sanding the ends of thinner strips
to mitre, it is expedient to use the angle stop
included in the scope of delivery.
1. Insert the angle stop (Pos. 5, Fig. 1) with the
stop rail into the designated groove.
2. Release clamping screw 1 (Fig. 8).
3. Set the required angle on scale 2 and re-
tighten clamping screw 1.
4. Guide the desired work piece at the limit stop
against the sanding disc as shown in the
image
7.3 Adhering or replacing the sanding
discs (Fig. 9):
Attention:
Before adhering or changing the sanding discs,
always disconnect the mains plug to prevent the
disc from starting up inadvertently. Risk of
injuries!
When changing the sanding disc, we recom-
mend removing the sanding table together with
the housing cover. This procedure is explained
in the section „Removing and attaching the
sanding table".
Along with your disc sander, your basic equip-
ment includes two sanding discs with 80 and
240 grit each; these are easily obtainable spare
parts. The sanding disc of your TSG 250/E is
covered with an adhesive silicone film:
This material ensures the completely uncompli-
cated exchange of sanding discs because they
do not stick but adhere firmly: Firmly enough to
work, but loose enough to be easily removed
later on. Replacing the discs is thus no problem,
either because of wear or because you need
discs with different grits while working.
1. We recommend removing the sanding table
together with the housing cover. This proce-
dure is explained in the section „Removing
and attaching the sanding table".
2. To change the disc, simply pull it off from the
plate.
3. Peel off the rear protective film of the new
disc.
