8.2 Back Angle Adjustment
1. Fold down the back. Refer to Unfolding/Folding the Back on page 41.
2. Loosen the jam nut on the placement screw located at the bottom of the back cane (Detail “A”).
3. Tighten the placement screw so that the screw and jam nut are snug against the bottom of the back cane (Detail “B”).
4. Remove the mounting screw that secures the adjustment square to the back angle plate (Details “A” and“C”).
5. Remove the adjustment square from the recess of the back angle plate (Detail “C”).
6. Position the adjustment square in the recess of the back plate with the hole located aligned with a number (FIGURE3).
7. Secure the adjustment square to the back angle plate with the mounting screw. Tighten securely.
For this procedure, refer to FIGURE2-5.
The numbers in the recess of the back angle plate are intended to define the resulting back angle of a chair that has 2 inch
seat drop (at 17 inch depth) and that is measured relative to true vertical with the chair sitting on a level surface. The plus
(+) sign increases the back angle and the minus (-) sign decreases the back angle. The resulting back angle will vary
somewhat depending on your chair configuration. Refer to FIGURE3 on page 46 to see these settings converted into back
angle relative to the seat.
Perform this procedure on both sides of the wheelchair at the same time.
Note the hole on the adjustment square. When the hole is positioned on top of the number inside the recess, this number
represents the back angle relative to true vertical. One side of the adjustment square provides back angles of -8°, 0° and -4°.
Flip the adjustment square over to obtain back angles of 8°, 4° and 0° (FIGURE3).

WARNING
If the adjustment square is installed into the recess of the back angle plate so that the adjustment square hole is not on top
of a number, DO NOT use this position. Otherwise, injury will occur. When the adjustment square hole is not on top of a
number, it prevents the locking pins from locking into position when the back is raised.
