• Place the stop rail (14) and fasten using the hexagon
socket screws (17) (Fig. 4a). Attention! It must be pos-
sible for the sanding belt (13) to run freely.
• To set the gap between the grinding table (7) and the
grinding wheel (4), proceed as follows (Fig. 4b):
- First loosen the three hexagonal nuts (23) beneath
the grinding table (7). Use a hexagon spanner size
10 for this (not included in the scope of delivery).
- Now clamp a panel or similar with a thickness of 2
mm between the grinding table (7) and the grinding
wheel (4).
- Tighten the hexagonal nuts again (23).
- Then remove the panel.
9.2 Replacing the grinding belt (Fig. 5 - 9)
• Pull out the mains plug.
• Loosen the hexagon socket screw (12)
• Loosen the screws (18).
• Take the grinding belt guard (19) off the grinding belt
holder (21). To do this, set the grinding belt holder
(21) at a slight angle.
• Turn the sanding belt tensioner (3) to the right in order
to reduce the tension on the sanding belt (13).
• Remove the grinding belt (13) to the front.
• Mount the new sanding belt in reverse order. Atten-
tion! Note the running direction on the housing and on
the inside of the sanding belt!
9.3 Adjusting the grinding belt
• Pull out the mains plug.
• Push the sanding belt (13) by hand slowly in the run-
ning direction.
• The sanding belt (13) must run centrally on the sand-
ing surface. If not, you can use the knurled screw (1)
to make adjustments.
9.4 Moving the sanding position of the sanding
belt (fig. 9−11)
• Loosen the hexagon socket screw (12).
• Move the sanding belt (13) upwards into the desired
position.
• Retighten the hexagon socket screw (12) to lock in
position.
• The grinding table (7) can be inserted in this position
to support the workpiece. To do this, first remove the
two hexagon socket screws (17) and then remove
the stop rail (14). The sanding table (7) can now be
pushed into the hole of the holder tube (20) and fixed
with the locking screw (8).

9.5 Replacing the sanding paper on the sanding
disc (fig. 12)
Dismantle the bottom disc guard (15) by removing the 2
screws (16). Pull the sanding paper off the sanding disc
(4) and attach the new sanding paper (quick-fit fastening
system). Refit the lower protective panel (15).
9.6 Use as a stationary machine
If your machine is to be used in a permanent location, it
is recommended you secure it to a workbench.
• To do so, mark the holes to be drilled:Place the sand-
er where it is to be mounted. Mark the location of the
holes to be drilled on the workbench.
• Drill holes through the workbench.
• Place the sander above the holes and insert suitable
screws from the top through the holes of the sander
and the workbench.
• Now fasten the sander from the underside of the
workbench using lock washers and matching hexag-
onal nuts.
9.7 Use as a mobile machine
If your belt and disc sander is to be used as a portable
tool, it is recommended you fasten it to a suitable mount-
ing plate which can easily be clamped to a workbench.
The mounting plate should be at least 19 mm thick and
sufficiently larger than the sander to allow space for the
clamps.
• Mark the holes to be drilled on the mounting plate.
• Follow the last three steps as described in section
"Use as a stationary tool".
Note:
Ensure that the screws are of suitable length. Spax
screws must not protrude so as not to damage the sur-
face, whereas hexagonal screws must protrude so that
washers and hexagonal nuts can be fitted.
9.8 Dust extraction connection
The machine is equipped with a suction port (10).
Connect a dust extractor when processing heavily dusty
materials.
Attention:The dust extraction must not be connected
when processing metals.
