SAFETY SUMMARY

NOTE: Check all parts for shipping damage. In case of damage, DO NOT use. Contact your Dealer for further instruction.

INSTALLATION WARNINGS

Stabilize from the ground up. A stable base, pelvis and footrests are requirements for any torso positioning system.

For proper installation of the Infinity Back and to reduce the risk of pressure sores, the adjustment procedures in this manual MUST be performed in the following order:

1. Adjusting the Mounting Hardware

2. Adjusting the Hinge/Angle (DUALFLEX ONLY)

3. Adjusting the Depth Hardware

4. Adjusting the Lateral Supports Ensure the Infinity Back is properly secured to the wheelchair BEFORE using. Upper

mounting pins must sit flush in the upper (swivel) cane clamps for the clamp lock to secure the Infinity Back to the wheelchair. Lower mounting pins must rest in the groove on the flange of the lower (fixed) cane clamps. Otherwise changes in seat depth will occur, making the wheelchair less stable.

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

STABILITY WARNINGS

The seat height, seat depth, back height, tilt angle, back angle, pivot point of seat frame, seating system, caster position, size and position of the rear wheels, wheel locks, anti-tippers, locking collar as well as the user condition directly relate to the stability of the wheelchair. Any change to one (1) or any combination of the fourteen (14) may cause the wheelchair to decrease in stability. Use EXTREME caution when using a new seating position.

SAFETY SUMMARY

STABILITY WARNINGS (CONTINUED)

ALWAYS make sure wheelchair is stable BEFORE reclining the back system. Rear wheels may have to be repositioned rearward depending on the degree of recline. ALWAYS ensure stability BEFORE using maximum amount of recline. TEST wheelchair BEFORE it is occupied by end user to ensure stability.

To maintain the stability of the wheelchair when moving the rear wheels to ANY forward position, the amount of recline MUST be limited to prevent the wheelchair from tipping onto the anti-tippers.

The necessary back angle MUST be selected BEFORE repositioning rear wheels forward. AS REGARDS RESTRAINTS - SEAT POSITIONING STRAPS - IT IS THE OBLIGATION OF THE DME

DEALER, THERAPISTS AND OTHER HEALTH CARE PROFESSIONALS TO DETERMINE IF A SEAT POSITIONING STRAP IS REQUIRED TO ENSURE THE SAFE OPERATION OF THIS EQUIPMENT BY THE USER. SERIOUS INJURY CAN OCCUR IN THE EVENT OF A FALL FROM A WHEELCHAIR.

SEATING PRESSURE WARNING

Skin condition should be checked very frequently after the installation and use of any new seating system.

IMPORTANT INFORMATION/INSTALLATION/ADJUSTMENT OVERVIEW

IMPORTANT INFORMATION

The best way to avoid problems related to pressure sores is to understand their causes and your role in a skin management program.

Your therapist and physician should be consulted if you have any questions regarding weight relief, self-examination of skin, or individual limitations and needs.

All cushions should be selected carefully. Working with your therapist, physician and equipment supplier is the best way to assure that a cushion choice matches your individual needs.

As the needs of the client become more complex, the cushion evaluation becomes more important.
