leg segments to the 50th percentile length (417 mm) and the thigh bar segment to the 10th percentile length (408 mm).
7.9.                              Attach the foot and lower leg assemblies to the seat pan assembly, either individually or by using the T-bar and lower leg assembly.  The line through the H-point sight buttons should be parallel to the ground and perpendicular to the C/LO of the seat.
7.10.                          Adjust the feet and leg positions of the 3-D H machine as follows:
7.10.1.                     Both feet and leg assemblies are moved forward in such a way that the feet take up natural positions on the floor, between the operating pedals if necessary. Where possible, the left foot is located approximately the same distance to the left of the centre plane of the 3-D H machine as the right foot is to the right.  The spirit level verifying the transverse orientation of the 3‑D H machine is brought to the horizontal by readjustment of the seat pan if necessary, or by adjusting the leg and foot assemblies towards the rear.  The line passing through the H-point sight buttons is maintained perpendicular to the C/LO of the seat.
7.10.2.                     If the left leg cannot be kept parallel to the right leg and the left foot cannot be supported by the structure, move the left foot until it is supported. The alignment of the sight buttons is maintained.
7.11.                          Apply the lower leg and thigh weights and level the 3-D H machine.
7.12.                          Tilt the back pan forward against the forward stop and draw the 3‑D H machine away from the seat back using the T-bar.  Reposition the 3‑D H machine on the seat by one of the following methods:
7.12.1.                     If the 3-D H machine tends to slide rearward, use the following procedure.  Allow the 3-D H machine to slide rearward until a forward horizontal restraining load on the T‑bar is no longer required (i.e. until the seat pan contacts the seat back).  If necessary, reposition the lower leg.
7.12.2.                     If the 3-D H machine does not tend to slide rearward, use the following procedure. Slide the 3-D H machine rearwards by applying a horizontal rearward load to the T‑bar until the seat pan contacts the seat back (see Figure 5-2 of Annex 5).
7.13.                          Apply a 100 N ± 10 N load to the back and pan assembly of the 3‑D H machine at the intersection of the hip angle quadrant and the T‑bar housing.  The direction of load application is maintained along a line passing by the above intersection to a point just above the thigh bar housing (see Figure 5-2 of Annex 5).  Then carefully return the back pan to the seat
