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).
The end mechanical stops are pre-set to 90° and stuck (Tubetanche Loctite 577 or equivalent). It is possible to adjust
then by moving the 2 screws M8 (appendix p.47 mark 18) but you need to stick them again in order to ensure a proper
sealing.
