1. Turn the knob to position MAN (counter-clockwise) and hold it in position.
2. Turn the outgoing drive shaft of the actuator with the help of an adjusting spanner.
3. In order to re-engage the reduction, release the knob (spring return).
VS model:
No declutching is required, the hand wheel has simply to be turned (appendix p.47 mark 10).
