WARNING
This procedure must be performed by a quali-
fied technician ONLY.
The position of the footrest, camber tube, back
angle, the tautness of the back upholstery as well
as the user's condition are directly related to the
wheelchairs stability. Any change to one (1) or any
combination of the five (5) may cause the wheel-
chair to decrease in stability. Use EXTREME caution
when using a new seating position.
NOTE: Note the position of the front hex screw before
removing to ensure proper reinstallation.

and locknuts that secure the back angle brackets to
the wheelchair frame.

ing positions for corresponding seat depths.
3. Position the back assembly with the mounting posi-
tion determined in STEP 2.
4. Secure the back assembly to the wheelchair frame with
the hex screws, washers, coved washers and locknuts.
