Section 3 - Back - includes the following:

Back Angle Adjustment

Folding/Unfolding the Back

Adjusting/Replacing Back Upholstery

Back Height Adjustment (Adjustable Backs Only)

WARNING

ALWAYS perform this procedure in the presence of an assistant. The position of the footrest, camber tube, back angle, the tautness of the back upholstery as well as the user's condition are directly related to the wheelchairs stability. Any change to one (1) or any combination of the five (5) may cause the wheelchair to decrease in stability. Use EXTREME caution when using a new seating position. The addition of anti-tippers may be required .

After ANY adjustments, repair or service and BEFORE use, make sure all attaching hardware is tightened securely - otherwise injury or damage may result.

2.Loosen the TOP hex screw locknut and slide the TOP hex screw away from the back angle mounting bracket to adjust the cam.

3.Adjust back canes to approximate back angle required.

5. Reassemble and torque hex screws 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.
