determine if new back upholstery is needed:
BACK UPHOLSTERY HEIGHT RANGES

If the back height required is within the range of the origi-
nal back height, only new back canes will be needed.
If the back height required is NOT within the range of the
original back height, new back upholstery and new back
canes will be needed.
NOTE: Existing hardware and inserts will be reused.

NOTE: Note position of the four (4) hex screws that se-
cure the back canes to the wheelchair frame to ensure

NOTE: Make sure the clamps on the spreader bar are
loose before removing the back canes from the spreader
bar, otherwise the back canes can be scratched.
8. Slide the existing back canes out of the back uphol-
stery and spreader bar.
9. Slide the new back canes through the existing/new
back upholstery and spreader bar.
