Fitting The Back To The Chair - Jay J3 BACK Manuel D'instructions

DETERMINING COMPATIBILITY
Wheelchair Types
The J3 Back is designed to be compatible with most wheelchairs
with the following exceptions:
Wheelchairs that are angularly adjustable, recline or tilt and result
in a back angle greater than 60 degrees from the vertical should not
be used.
WARNING
Use with these types of wheelchairs may cause the back
to accidentally disconnect from the wheelchair resulting
in a fall and the potential for serious injury.
Wheelchair Dimensions
The J3 Back is designed to replace the wheelchair's sling uphol-
stery. Prior to installation determine if the wheelchair used has
compatible back canes, by measuring the width between your back
canes as seen in Figure 1. Then using that measurement, check
Table 1 to determine if the back will fit your chair.
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. 2) and
refer to Table 2 to ensure your back canes are compatible.
If you cannot determine that the back canes are compatible
please contact your authorized Sunrise Medical provider
or Sunrise Medical customer service.
