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

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.
