If the belt tracking cannot be adjusted centred:
Clean the drive wheel (12) and the contact wheel (13)
with compressed air.
Check the drive wheel and the contact wheel for wear,
deformation and damage. Have damaged components
replaced without delay!
Replacing the grinding belt.
Before any work on the machine itself, pull the
mains plug.
Loosen screw (14) and fold down the side cover (15).
Tilt lever (16) downward to release
the tensioning device.
Remove the old grinding belt.
Before mounting the new grinding
belt, observe the running-direction
indication on the rear of the grinding belt! It mus corre-
spond with the rotation direction of the drive wheel.
Place the grinding belt both around the drive wheel (12)
and around the contact wheel (13).
Tilt lever (16) upward to tension the
grinding belt.
If the grinding belt can not be ten-
sioned sufficiently, the tensioning
device must be readjusted. Loosen
both screws (17), change the position of the tensioning
device and retighten the screws.
Shut the side cover (15) and tighten screw (14) again.

REMARK: The sum of the measured emission value and
respective measuring inaccuracy represents the upper
limit of the values that can occur during measuring.
Wear hearing protection!
