MAINTENANCE WORK AND REPLACEMENT OF WEARING PARTS
Machines with single-phase AC motor
(mains voltage 230 V and 220 V):
Turn the switch button in position -TEST- and hold the
switch button for around 2 seconds in this position (Fig.
40). At the same time control the sanding belt tracking.
After this release the switch button.

If the sanding belt runs to the front (towards A in Fig. 41) or
to the back (towards B in Fig. 41) the setting of the sand-
ing belt regulation is necessary (
the sanding belt tracking). If the sanding belt tracking is
alright, mount the side cover.
7.3.2 SETTING THE SANDING BELT TRACKING
Should the setting of the sanding belt tracking be necessary,
proceed as follows:
1
Lift the sanding drum off the floor by turning the lowering
lever at the handle upwards.
2
Switch off the machine!
3
Remove the side cover.
4
Check whether any soiling at the tensioning roller calls for
readjustment. If so, the tensioning roller must be cleaned
(
Section 7.1.1, Dismantling and cleaning of drive unit)
and the sanding belt tracking must be checked again (
Section 7.3.1, Checking the sanding belt tracking).
5
Always set the sanding belt tracking using a sanding belt
with as fine a grit size as possible (= flexible sanding belt).
This is because the more flexible the sanding belt, the
precisely it is possible to set the tensioning roller.
Mount the sanding belt (
sanding belt) and carry out a test run (
Checking the sanding belt tracking).
If the sanding belt is running out of true (towards A or
B in Fig. 41), it must be turned around and another test
performed.
If the sanding belt runs to the front (towards A in Fig. 41)
and after turning over to the back (towards B in Fig. 41)
or vice versa, the sanding belt is of poor quality and is not
usable (conical sleeve)!
