The Jay J3 Back is intended to provide a back support
for a wide variety of wheelchair users. It is designed to
provide simple, comfortable and effective support to help
maximize function and increase sitting tolerance. In addi-
tion, it is light-weight, durable and easy to use.
The back can be installed onto a wide range of wheel-
chairs.
Maximum user weight: 300 lbs. (136 kg).
The intended lifetime of the back rest is 4 years.
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.
WARNING

Wheelchair Types
The J3 Back is designed to be compatible with most wheel-
chairs with the following exceptions:
Wheelchairs that are angularly adjustable, recline or tilt and
result in a back angle greater than 60 degrees from the verti-
cal 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
upholstery. 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 diam-
eter. The J3 back hardware can be mounted on wheelchair
back canes ranging from 3/4” (1.9 cm) to 1 1/8” (2.85 cm).
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.

is achieved.
Hardware Installation Instructions (Figs. 3, 4, 5)
1. Remove the existing wheelchair back according to the
wheelchair manufacturer’s instructions.
2. Visually determine the desired location of the receivers
on the wheelchair’s back canes. The mounting hard-
ware should be at approximately equal heights on each
back post (Fig. 3) and parallel to the seat frame (Fig. 4).
Higher locations on the back canes are generally better.
3. Attach the hardware receivers. (Fig. 5)
a. Loosen the clamp screws (A) with the enclosed 4mm
hex key. NOTE– For large tube diameters, clamp
screws may have to be removed completely.
b. Attach and align receiver to the wheelchair back
canes (B).
c. Hand tighten clamp screws (A). NOTE– Receivers
may require additional lateral adjustment to ensure
proper alignment.
Attaching and Aligning the J3 Back Shell (Fig. 6)
a. Loosen bracket nuts (C) and mounting pin nuts (F)
using 10mm box-end wrench until hardware can
move easily in all directions.

ADJUSTMENT
ADJUSTING J3 HEIGHT, DEPTH AND
ANGLE
The first phase of the J3 Back hardware installation is com-
plete. It is now the appropriate time to have the user seated
back in the chair for personalizing the J3 Back. Do not have
the user apply full pressure on the back as it is not fully tight-
ened to the full torque requirements.
1. Height Adjustment (Fig. 10)
a. With the user in the chair, identify the desired height of
the back. Once identified, have the user remove pres-
sure from the J3 Back by leaning or sliding partially for-
ward if possible to allow the adjustment to take place.
b. Loosen the bracket nuts (A) and adjust the height of the
back shell to required position.
c. Securely tighten the bracket nuts (A). The recommend-
ed torque specification is 75-85 in-lbs. (8.5 - 9.3 Nm).
NOTE: After height adjustment is complete, check that the
width was not inadvertently changed.
2. Depth/Angle Adjustment (Figs. 11, 12, 13 & 14)
Please note there are two types of hardware that can be
ordered– standard hardware (Fig. 11) or the longer, adjust-
able hardware (Fig. 12). Both sets of hardware are adjusted
the same, but the standard hardware allows for 2 inches (5
cm) of depth adjustment (Fig. 11) while the extended hard-
ware (adjustable hardware) allows for a total of 3.4 inches
(8,65 cm) of depth adjustability (Fig. 12).
a. To adjust J3 Back depth and angle loosen left and right
nuts (Fig. 14-B) on bracket slots.
b. Adjust depth and/or angle and securely tighten. The rec-
ommended torque specification is 100-110 in-lbs. (11.3 -
12.4 Nm). Ensure that none of the depth adjustment nuts
(Fig 14-B) will slip or rotate.
c. If additional depth is needed, remove back from receiv-
ers. Remove screws (Figs. 11-D, 12-D) from receiver
using the enclosed 4mm hex key, and reposition to
desired depth. Note: Prior to replacing the screws the
application of a suitable medium strength threadlocker
e.g. loctite 243 is strongly recommended to the receiver
and screw threads, if the back is to be repositioned.
Tighten screws to 25-35 in-lbs. (2.8 - 4 Nm).
WARNING
Ensure that all hardware has been properly tightened
once all adjustments have been completed and the
J3 Back is ready for use.
WARNING
To ensure optimal security of the back fitment, the lock-
ing pin must be inserted before the backrest can be
used, (Fig. 15 & 16).

J3 BACKREMOVAL AND REPLACEMENT
REMOVAL AND REPLACEMENT
Removal
Following installation and adjustment, the back can be easily
removed from the wheelchair if necessary. To remove, push
each release lever forward to unlock (Fig. 27). Once both
levers are in the forward position, simply lift the back straight
up (Fig. 28) using the handle located on the top of the back.
Proper reattachment after removal
To reattach the back to the hardware receivers, simply line
up the pins to the receivers and push into place (Fig. 29). If
properly inserted the pins will “click” to a locked position.
WARNING
If you are uncertain if you have heard the locking
“click”, pull up on the back using the handle to
ensure that it has been securely locked.
Locking Pins (Fig. 30)
The J3 Back comes with two locking pins which, when
secured, prevent the back from being released from the
chair. To lock, insert the pins (A) into the mounting receivers
(B). Simply remove the pins if the quick-release capability is
desired.
