Adjusting the Backrest Height
Tools Needed:
• 5/32” Allen Wrench
Note:
In order to adjust the backrest height, it is helpful to remove the backrest upholstery. Therefore, make a note
of the tautness of the backrest upholstery before removing it so you can reinstall it to approximately the same degree
of tautness.
1. Remove the backrest pad. See “Velcro
®
-Style Adjustable Back Upholstery” or “Tension Adjustable by Straps
Back Upholstery” on pages 7-1 to 7-3.
2. On both sides of the chair, remove the Allen screw that secures the backrest post inside the backrest. See
Figure 4-4.
3. Reposition both backrest posts to the desired height inside the backrest, and reinsert and securely tighten the
two Allen screws.
4. Make sure both backrest posts are at the same height in the backrest.
5. Reinstall the backrest upholstery. See “Velcro

-Style Adjustable Back Upholstery” or “Tension Adjustable by
Straps Back Upholstery” on pages 7-1 to 7-3.

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. You should be able to
adjust the backrest height approximately four times without reapplying thread lock to these screws. TiLite requires
that you reapply Vibra-TITE
®
VC-3 after every fourth adjustment.
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.
