Back Angle Adjustment


Perform this procedure on both sides of the wheelchair at the same time.
1. Loosen, but DO NOT remove the locknuts and hex screws that secure the back angle bracket to the seat rail and the back cane.
2. Loosen the top locknut and slide the top hex screw away from the back angle bracket to adjust the cam.
3. Adjust back canes to back angle required.
4. Adjust cam to achieve desired position.

An indexing notch has been put on the cam to help determine cam position for desired back angle adjustment.
5. Secure cam in desired position. Tighten hex screws and locknuts securely. DO NOT distort frame tube.
 As shown in FIGURE 1, the adjustment cam can be rotated to several different positions thus changing the overall back angle
relative to the seat rail.
