Adjusting the Back Height

The seat depth, back height/angle, seat angle, size/position of the front casters,
size/position of the rear wheels, anti-tipper model, as well as the user condition
directly relate to the stability of the wheelchair. Any change to one (1) or any com-
bination of the ten (10) may cause the wheelchair to decrease in stability. These
adjustments MUST be performed by a qualified technician.
NOTE: For this procedure, refer to FIGURE 6.3.
NOTE: Back canes must be adjusted to the same height.
