Attention! It must be possible for the sanding wheel (3)
to run freely. The distance between the sanding table (6)
and the sanding wheel (3) should be max. 2 mm.
To set the gap between the sanding table (6) and the
sanding wheel (3), proceed as follows (Fig. 19, 20):
1. Release the clamping screw (23).
2. Loosen the three nuts (16), under the sanding table
(6). Use a hexagon spanner AF10 for this (not includ-
ed in the scope of delivery).
3. Now clamp a panel or similar with a thickness of max.
2 mm between the sanding table (6) and the sanding
wheel (3).
4. Tighten the nuts (16) and the clamping screw (23).
5. Then remove the panel.
10.3 Setting the speed (Fig. 1+12)
With the speed control (4b) it is possible to set the speed
of the grinding wheel (3) and the speed of the grinding
belt (13).
Notes:
The speed can also be changed during operation.
The speed that makes sense when working depends on
what tasks you are doing with the product.
We recommend determining the speed using practical
tests.
The speed of the product can be read on the display.
10.4 Sanding
• Always hold the workpiece firmly during sanding.
• Do not apply excessive pressure.
• The workpiece should be moved back and forth on the
sanding belt or the sanding wheel when sanding. This
prevents the sanding paper from becoming worn on
one side.
ATTENTION
Pieces of wood should always be sanded with the grain
to prevent them splitting.
ATTENTION
If the sanding wheel or the sanding belt jam while you
are working, remove your workpiece. Then wait until the
product has reached its maximum speed again before
you continue working.
