9.3 Backrest height
The overall height of the backrest can be
adjusted by loosening the two knobs, then
positioning to the shoulder height of the
user. Once in position the knobs should be
retightened securely. The height can be fine
tuned when the user is in the seat. When
the height is lowered the cushion must be
pulled around the bottom of the backrest and
secured to the back of it via the Velcro and
elastic tabs.
Use caution when adjusting to minimum
setting as fingers could become trapped
between moving and static parts.
