InstaLLIng thE mountIng harDWarE
Please read the following instructions before beginning instal-
lation.
To install the J3 Back, it is best to begin without a user in
the wheelchair. Once the back has been installed and minor
adjustments are needed the user can be seated back in the
wheelchair.
tools required (included with J3 Back)*
• 4mm hex key
• 10mm box end wrench
Note: Wherever torque settings are specified, it is strongly
recommended that a torque meter (not included with
Jay3 Back) is used to verify correct torque specification
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.
b. attach the J3 Back to the hardware receivers by
inserting left and right mounting pins (D) in the left
and right receivers (E).
c. locate back to the approximate location, relative to
both chair and user.
d. Hand tighten nuts on the inside of the mounting pin
(F).
NOTE– Back depth and angle may require addition-
al adjustment to ensure proper fit to the user.
e. Hand tighten bracket nuts (c). NOTE– Back height
may require additional adjustment to ensure proper
fit to the user.
f. Test back release by pressing the release levers
forward and removing the back off the chair. (See
Removal and Replacement section for further
details.) Proper alignment of the mounting hardware
and back is achieved when smooth attachment and
release can be easily done.
g. If proper alignment has not been achieved, adjust
the components until properly aligned.
h. Once properly aligned, tighten the hardware receiver
clamp screws. The recommended torque specifica-
tion is 75 - 85 in-lbs (8.5 - 9.3 Nm).
