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 correspond with the rotation direction of
the drive wheel.
Place the grinding belt both around the drive wheel (21)
and around the contact wheel (19).
Tilt lever (5) down to tension the
grinding belt.
Shut the side cover (23) and tighten
screw (22) again.
Mount the chip/grinding-dust box
(11) and check the gap clearance of
the grinding rest.(figure 4)
Switch the machine on and adjust the belt run.
Operating instructions.
Switching on:
Disengage and fold up the safety pushbutton (15). Press
