 Refer to figures
12 to 14 to access the sensor area.
 Unscrew the 4 screws (1).
 Remove the casing (2) in the direction of the arrow shown in the figure.
There is also a thin layer of silicone fixing the casing to the electrospindle, but a slight force is
enough to remove it.
 When replacing the casing (2), be careful not to damage the sensor cables inside. Use Loctite
510 (or an equivalent product) on the edge of the casing.
