3. Indication of speed:
The speed indicator (H) is to the right of the rotation switch (G).
It displays the selected speed using 5 LED lights. If all lights are
flashing, the device runs at the highest speed.
E. Before the first use, make sure that you let the handpiece run for
about 30 minutes at approx. 8.000 rpm (2 LED lights of the
speed indicator (H) should flash). This is necessary to bed in the
carbon brushes of the motor.
Note:
A different running noise between clockwise and counter-
clockwise rotation is normal and caused by bedding in of the
carbon brushes or by running in of bearings.
