Mounting / disassembly of the cover and position indicator
For the wiring and setting of the actuator, it is necessary to remove the cover.
Mounting of the cover (appendix p.47 mark 2) : make sure that the seal ring (appendix p.47 mark 7) is correctly
placed in its position, mount the cover and tighten the 4 screws M6 (appendix p.47 mark 3, torque : max. 6Nm).
Mounting of the position indicator for VR (appendix p.47 mark 1) : fit the indicator onto the outgoing axle (according the dia-
gram p.28).
Mounting of the position indicator for VS (appendix p.47 mark 1) : mount the seal ring and the indicator then the window with
the 4 screws M4 (according the diagram p.28).

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 en-
sure a proper sealing.
