Next check that the back canes
are a compatible diameter. The
strap style back mounting hard-
ware may be used on back canes
from 0.62 to 1.1 inches (16mm to
28mm) in diameter. (Fig. 2)
If you cannot determine that the
back canes are compatible please
contact your authorized
Sunrise Medical provider or
Sunrise Medical customer service.
FITTING THE J2 BACK
The J2 Back is designed to replace the wheelchair's sling uphol-
stery. The initial installation should be done without the foam insert
in the back shell. Tighten all fasteners to 20 in.-lbs. (2.3 N-m) using
a Phillips No. 2 screwdriver.
1. Remove the upholstery from the back of the wheelchair.
2. Attach one bottom post bracket to each upright post of
the wheelchair.
a. Check the diagram for the proper holes for different wheel-
chair post diameters. (The bracket comes assembled to
attach to 7/8"–1" (2.2cm -2.5cm) posts. To attach 5/8"–3/4"
(1.6cm-1.9cm) posts remove caps and insert screws into
both inside holes.) Wrap the band around the wheelchair
post. Screw "A" may have to be loosened to align strap hole
with barrel nut. Place a washer on the screw and insert
through the proper hole.
b. Insert screw "B" into the side of the bracket and tighten
firmly to 2.3 N-m (20 in-lbs). Ensure that the screw engages
the insert inside the bracket.
c. Place caps over both screw heads.
d. To adjust the height of the bracket, loosen screw "A" until
bracket slides freely on wheelchair post. Once proper height
of the back is determined, tighten screw "A" to 2.3 N-m
(20 in-lbs). All future adjustments of the back height are done
with this screw.

Figure 2
Place the J2 Back in the wheel-
chair so that the bottom pins on
the back shell slide into the bot-
tom post brackets and the top of
the back rests against the
uprights. The top hooks (on the
upper portion of the back shell)
should rest flush against the
posts.
4. Bottom width adjustment.
Remove the J2 Back from the
wheelchair. Lift tab on bottom
brackets with a screwdriver tip
and slide the pins to adjust width
to match wheelchair post width.
Check to ensure the pins extend
to the full width of the bottom
post brackets. Count the num-
ber of holes exposed to ensure
the back is adjusted evenly on
both sides.
5. Top width adjustment.
Depress the silver pin on top
brackets with a screwdriver tip
and slide top bracket to adjust
width to match wheelchair post
width. Ensure that the back is
adjusted evenly on both sides.
Replace back in wheelchair.
6. Assess and adjust back
height.
Replace the foam insert. Assess
client for back height. Position
the user's hips to the back of the
wheelchair. The center of the
bottom pin on the J2 Back
should be placed at approxi-
mately the level of the PSIS or
Bottom
S1-S2 spinal level of the individ-
Post
ual. (The PSIS is the top, rear of
Bracket
the pelvis.) This will help main-
tain a stable pelvis when the
back angle is adjusted. To adjust
Bracket
the height of the back, loosen
Body
screw "A" and slide post brackets
up or down. Once proper height
is determined, tighten brackets
firmly to 2.3 N-m (20 in-lbs).
