￿ WARNING

ALWAYS perform these procedures in the presence of an assistant. The position of the footrest, camber tube, seat angle, 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 or any combination of the five 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 occur.

8.1Unfolding/Folding the Back

￿ WARNING

After unfolding the back, ensure that the plunger pins are fully engaged in the mounting holes of the adjustment square in the back cane mounting brackets (Detail “A” in FIGURE 2). Back MUST be locked securely in place. Otherwise, serious injury could result.

1.To fold the back, pull up on the back release cord and push the back toward the seat of the wheelchair (Detail “A”).

2.To unfold the back, pull up on the back release cord and lift the back away from the seat until the back locks into place (Detail “B” and Detail “C”).

An audible “click” will be heard when the plunger pins fully engage into the adjustment square (Detail “C”) and the split ring will be flush up against the back stop insert.

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.
