INTRODUCTION
Sunrise Medical recommends that a clinician such as a doctor
or therapist experienced in seating and positioning be con-
sulted to determine if a J3 Back is appropriate. Backs should
only be installed by an authorized Sunrise Medical supplier.
THE JAY J3 BACK
The Jay J3 Back is designed to provide the important benefits of a
proper back support for a wide variety of users. It is designed to
provide simple, comfortable and effective support to help maximize
function and increase sitting tolerance. In addition, it is light-weight,
durable and easy to use.
Maximum user weight:
300 lbs. (136 kg)
500 lbs. (227 kg) for sizes 22", 24" and 26" widths
WARNING
Installing a back support on a wheelchair may affect the
center of gravity of the wheelchair and may cause the
wheelchair to tip backwards potentially resulting in injury.
Always assess for the potential need for anti-tippers or
amputee axle adapter brackets to be added to the
wheelchair to help increase stability.
WARNING
Do not use J3 Back to push or lift wheelchair. Improper
use may cause the back to unexpectedly detach from
the wheelchair.
WARNING
Do not use the J3 back handle to lift wheelchair. It is
intended only for back removal.
