13 4.0 Assembly 4.1 Thumb Rotator Assembly Setting and Assembly Fig. 22: The full thumb rotator assembly is illustrated (fig. 22). To increase the force required to rotate the thumb, remove the Nut Cap and use the 8 mm Spanner to tighten the M4 Locking Nut. The grub screw will need to be loosened to tighten the nut. Ensure the Clutch Plate is not contaminated, as this will affect performance. Clutch Plate Hand tighten with fingers and then turn a further 120 to 150 to give the desired thumb friction depending on patient preferences (fig. 23), using the 8 mm Spanner. The wire will now travel down through the centre of the spigot. Fig. 23: 13 of 25

14 4.2 Attaching the Thumb Remove the base cap on the thumb rotator assembly by removing the two M2x5 mm Screws (fig. 24). Fig. 24: Remove the knuckle cover from the thumb assembly by removing the two M2x4 mm Screws (fig. 25). Fig. 25: Remove the knuckle assembly from the thumb assembly by removing the M3 Grub Screw (fig. 26). Fig. 26: Screw the knuckle onto the thumb rotator assembly using 3 M2x5 mm Screws (fig. 27). Fig. 27: 14 of 25

15 Using a torque driver set to 1 Nm, re-attach the thumb to the single knuckle assembly (fig. 28). Fig. 28: When inserting the M3 grub Screw into the single knuckle a T6 torque driver, set to 1.0 Nm, must be used (fig. 28). Screws supplied are recommended for single use only. Always use new screws for final assembly. Slide the knuckle fairing over the back of the thumb and attach using two M2x5 mm Screws (fig. 29). Thumb digit wire should be fed through the central hole in the thumb assembly exiting at the base cap end. Re-attach the base cap, using the screws previously removed (fig. 24). Fig. 29: Add connector onto each of the thumb digit wires as shown.
