BACKREST ANGLE
WARNING: THE CHAIR MUST BE UNOCCUPIED WHEN MAKING THIS
ADJUSTMENT.
1. Using a
9
/
16
" (14 mm) wrench,
loosen (DO NOT REMOVE) the
2 nuts on each side behind
the backrest.
2. To adjust the backrest angle,
loosen the locking nuts
(one on each side).
The backrest angle adjustment can vary from 95 to 108 to accommodate
the shape of a user’s back. Adjust the backrest tilt for a comfortable
position with the lower back supported as well as the head so that there
is a good field of vision in front of you.
A neck rest (optional) can be used; it attaches to the backrest with a
strap. The neck rest must be placed at the base of the head and neck
in order to fill the void based on the user’s comfort.
