The owner of this equipment is responsible for making sure that it
has been set up and adjusted by an Authorized Dealer under the
advice of a healthcare professional. The back and hardware may
require periodic safety and function checks. Adjustments should
be performed by your Authorized Dealer. Always use parts
and/or accessories that have been recommended or approved by
Sunrise Medical.
The J3 back is designed to be compatible with most wheelchairs with
the following exception: Wheelchairs that are angle adjustable with
recline or tilt that result in a back angle greater than 60° from the
vertical should not be used with the J3 back system.
A. WHEELCHAIR DIMENSIONS
1. The J3 Back is designed to replace the wheelchair's sling
upholstery. Prior to installation determine if the wheelchair
used has compatible back canes, by measuring the width
between your back canes as seen in (Fig. 5).
2. Next check that the back canes are a compatible diameter.
The J3 back hardware can be mounted on wheelchair back
canes ranging from 3/4" to 1 1/8". Measure your back cane
diameter (Fig. 6) and refer to Table 2 to ensure your back
canes are compatible.
3. If you cannot determine that the back canes are compatible
please contact your authorized Sunrise Medical provider
or Sunrise Medical customer service.
