While looking at the rear of the chair, hold the adaptor bar, so that the "T" bar is away from you and you can see the white stripes on the
back of the end tubes. Place one of the end caps over one of the axle tips and slide the other end out and place it over the opposite axle tip.
Now move the adaptor attachment until it is centered (Fig. C). Note the number of dimples visible on the bar of the adaptor attachment
[they should be the same number on both sides] (Fig. D). Remove the assembly and move the adjuster bars outward so that you can see
the same amount of dimples that you noted before. Then move it four (4) further for consideration of the spring loaded end caps [i.e. you
count two (2) exposed dimples then move the adjuster bars out so you have six (6) exposed dimples] (Fig. E). Position the set screws in the
correct dimples then tighten only a few rotations, checking so the correct number of dimples show on each side.

Tighten the set screw just so that it holds the bar in the correct position. Next tighten the bolt on the clamp to secure the position of the tube
(Fig. F). Once secure, repeat for the other side. Next place the folding bar back on the chair to ensure you have it set to the proper width (Fig.
G). If set up properly, the inside edges of the end caps will be within the white strips of the tube (Fig. H). If not, adjust the number of dimples
visible as needed to achieve the proper spring pre-load setting as indicated by the end caps edge being over the white strips by loosening the
set screw and the bolt and position as needed and then tighten again.

Adjustments made to the wheelchair set-up could affect the orientation of the folding adaptor bar. Adjust the adaptor bar
whenever changes are made to the chair.
