NOTE: For this procedure, refer to FIGURE 7.9.
The seat height, seat depth, back angle, seating system, size/position of the rear
wheels, size/position of the front casters, as well as the user condition directly relate
to the stability of the wheelchair. Any change to one or any combination of the nine
may cause the wheelchair to decrease in stability. These adjustments MUST be per-
formed by a qualified technician.
1. Loosen, but do not remove the front hex bolt that secures the back angle plate to the
wheelchair frame.
2. Remove the rear hex bolt, washer and locknut that secure the back angle plates to the
wheelchair frame (Detail "A" of FIGURE 7.9).
3. Refer to Figure 10.9 to determine the mounting hole in the back angle plates for the
necessary back angle.
4. Reinstall the rear hex bolt, washer and securely tighten with locknut (Detail "A" of
FIGURE 7.9).

parallel to the ground/floor. Refer to Using/Installing/Adjusting Cantilever Arms on
page 47.
