Turn the forearm frame over to check that the holes in
the finger mount are in line with the two screw holes in
the forearm frame.
Align the left forearm frame and finger mount as
shown. The mount can be fitted either way up.
Line up the thumb and the forearm frame, noting the
position of the square tab on the thumb and the
matching hole in the frame, circled in red.

Fit two M2 x 10mm pan-head screws through the holes
and carefully tighten them to secure the finger mount.
2
Press the tongue of the finger mount into the long slot
in the end of the forearm frame.
6
Press the parts together so that the tab locks into the
hole and the thumb fits flush against the frame.
