BACK ANGLE ADJUSTMENT (FIGURE 1)
NOTE: 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.
NOTE: 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. Torque all hex screws and locknuts to 960-1020
inch pounds (80-85 foot pounds).
NOTE: 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.
