10. Start up
m Attention!
Always make sure the device is fully assembled
before commissioning!
10.1 On/off switch (5) (fig. 13)
• It is possible to switch the sander on by pressing the
green "I" button.
• In order to switch the sander off again, it is necessary
to press the red "0" button.
Warning:
Never reach over the device to turn the belt and disc
sander on or off! Risk of injury!
10.2 Sanding
• Always hold the workpiece firmly during sanding.
• Do not apply excessive pressure.
• The workpiece should be moved back and forth on
the grinding belt (13) or the grinding wheel (4) when
grinding. This prevents the sanding paper from be-
coming worn on one side.
Important! Pieces of wood should always be sanded with
the grain to prevent them splitting. Attention! If the grind-
ing wheel (4) or the grinding belt (13) jam while you are
working, remove your workpiece. Then wait until the de-
vice has reached its maximum speed again before you
continue working.
11. Working instructions
11.1 Grinding chamfers and edges (Fig. 14)
The worktable can be infinitely adjusted from 0 ° to 45 °.
• To do so, loosen the locking screw (8).
• Set the worktable to the desired angle. Attention:The
worktable should never be more than 2 mm from the
grinding wheel (4), even when tilted!
• Tighten the locking screw (8) again.
11.2 Sanding small end surfaces using the trans-
verse stop (fig. 15a, 15b)
The supplied transverse stop (6) makes precise sanding
easier. The transverse stop (6) can be used to set grind-
ing angles in addition to the inclination of the grinding
table (7). We recommend its use when grinding (short)
faces.
Note:
Always move the workpiece from the left to the centre
of the sanding disc, never beyond! Risk of injury due to
workpiece being thrown away!
11.3 Horizontal and vertical sanding (fig. 9−11, 16)
Your sander can sand both vertically and horizontally.
The worktable can be used for both applications.
• 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 loosen 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).
Note:
Sand long workpieces in the vertical position by moving
the workpiece evenly over the sanding belt (13).
11.4 Surface sanding on the sanding belt (fig. 17)
• Hold the workpiece (W) firmly. Watch your fingers!
Risk of injury!
• Keep the workpiece pressed firmly against the stop
rail (14) guiding it evenly over the sanding belt (13).
Attention:Be particularly careful when sanding very
thin pieces and extra long pieces (perhaps even with-
out stop rail (14)). Apply only enough pressure to al-
low the sanding belt (13) to remove sanded material.
11.5 Grinding concave curves (Fig. 18)
Warning:
Never attempt to sand the end pieces of a workpiece on
the idler drum (R). If you do so, the workpiece (W) may
be ejected. Risk of injury!
Always sand concave curves using the idler drum at the
sanding belt (13).
• Hold the workpiece firmly. Watch your fingers! Risk
of injury!
• Guide the workpiece evenly over the sanding belt
(13). Attention:Be particularly careful when sanding
very thin pieces and extra long pieces.
