5.2 Back Angle Adjustment

WARNING
If the adjustment square is installed into the back angle plate so that a number does not appear next to the indent, DO NOT use this
position, otherwise injury will occur. This position of the adjustment square does not allow the locking pins to lock into position
when the back is raised.
After unfolding the back, ensure that the plunger pins are fully engaged in the mounting holes of the adjustment square in the back angle
plates. Otherwise, serious injury could result.
 The numbers on 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 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 indent on the adjustment square. When the adjustment square is positioned in the back angle plate, the number that is located
directly next to the indent will be 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°.
When adjusted properly, the back should have a small amount of movement when locked in the open position. Plunger pins should snap
in and release easily without resistance.
