INSTALLING AND ADJUSTING THE DEEP
CONTOUR BACK
Installing the Deep Contour Back.
Place the J2 Deep Contour Back in the wheelchair so that the bot-
tom pins slide into the the bottom Universal Post Bracket hard-
ware receivers. The Back's top hooks should rest against the
wheelchair back posts. The bottom pin head should extend past
the outside edge of the post bracket receiver (Fig. 3). The Deep
Contour Back may require some simple adjustments. If the bottom
pin head does not extend past or extends too far, adjust the bot-
tom width as instructed in "Adjusting the bottom width".
Adjusting the bottom width
1. Remove the Back from the
wheelchair.
2. Using a screwdriver tip, lift
tab on Back's bottom pin
locator bracket
3. The pin should slide in or
out of the locator bracket
to adjust the Back's
Hardware width.
4. Center the Back on the
wheelchair by exposing
an equal number of holes
(Fig. 4) on each locator
bracket.
Adjusting the top width
1. Using a screwdriver tip,
depress the silver pin (Fig. 5)
in the adjustment hole on
the inside of the Back Shell
adjacent to the top hook
hardware.
2. The top hook assembly can
now slide into a wider or
narrower pin location.
Center the Back on the
wheelchair by placing the pin
in the same location on each
side of the Back.

INSTALLING THE TOP QUICK-RELEASE
QUARTER TURN BRACKET HARDWARE
1. Attach one top quick-release quarter turn bracket to each
upright post of the wheelchair.
a. The top quick-release quarter turn bracket is designed to
fit on 5/8", 3/4", 7/8" and 1" (1.6, 1.9, 2.2 and 2.5 cm)
diameter back post tubing. (The bracket comes assem-
bled to attach to 7/8" or 1" (2.2 or 2.5cm) tubing) Check
Figure 6 to determine which strap hole is appropriate for
the installation. Wrap the strap around the wheelchair
post. Screw "A" may have to be loosened to align the
strap hole with the barrel nut located inside the bracket
body. Place a washer on screw "B" and insert the screw
through the appropriate hole in the strap.
b. Tighten screw "B" (to 2.3 N-m (20 in-lbs)) into the barrel
nut through the side of the bracket body. Tighten the
opposite screw if necessary.
c. Snap the screw caps over both screw heads.
d. To adjust the height of the bracket, loosen screw "A" until
the bracket slides freely on the back post. Once the
proper height of the back is determined, tighten the
screw firmly to 2.3 N-m (20 in-lbs). All future adjust-
ments of the back height are done with screw "A".
e. Always turn the quick-release quarter turn bracket to the
"DOWN" position (Fig. 7) to secure the top hook in
place.
CAUTION– The top quick-release quarter turn brackets must be in their
downward position when the back is in use. Improper use may cause
the back to unexpectedly detach from the wheelchair.
CAUTION– Do not use J2 Deep Contour Back to push or lift wheelchair.
Improper use may cause the back to unexpectedly detach from the
wheelchair.
NOTE– The back is properly secured when the bottom pins are resting in
the lower post brackets and the upper quick-release quarter turn
brackets are installed above the back support's top hook brackets
with the quick release mechanism pointing down.
