WARNING
The threads on the Allen screws that secure the backrest posts to the backrest have been treated with a Vibra-TITE
®
VC-3, a locking and sealing coating, to reduce the possibility 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.
