WARNING

that they will become loose. TiLite requires that you reapply
Vibra-TITE

VC-3 each time your backrest is replaced.
If
you ignore this Warning, your backrest posts could become loose or disconnected from the wheelchair, and you could
fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair.
