IV. INSTALLATION, USE, AND ADJUSTMENTS
B. JAY FIT 2U FP (Four Point) Hardware
Please read the following instructions before beginning. To mount the JAY FIT 2U Back with FP
(Four Point) hardware, it is best to begin without a user in the wheelchair. Once the back has been
mounted and minor adjustments are needed, the user can be seated back in the wheelchair. This is
supplied as standard hardware.
Tools required (included with the JAY FIT 2U Back)
1. 4mm Hex Key
2. 10mm Box End Wrench
Back Hardware Mounting
1.
Remove existing back components
a.
Remove the existing wheelchair back according to the wheelchair manufacturer's
instructions.
b.
Remove any pre-existing back hardware or components.
2.
Locating the hardware receivers
a.
The back shell should come with mounting brackets (A) attached.
b.
Visually determine the optimum clamp receiver (B) location on the back canes. The
mounting hardware should be at approximately equal heights on each back post (D) and
parallel to the seat frame. (Fig. 10)
NOTE – A higher location on the back canes is generally better.
3.
Attaching the hardware receivers
a.
Using the 4mm hex key, loosen the clamp screws (C).
NOTE: For large tube diameters, the clamp screws may have to be removed completely.
b.
Attach and align the receiver to the wheelchair back canes (D).
c.
Hand tighten the clamp screws (C).
d.
Using a 10mm wrench, loosen the bracket nuts (E) and the mounting pin bolts (K) until you
can move the hardware easily in all directions for adjustment.
e.
The receivers may require additional lateral adjustments to ensure proper alignment.
4.
Attaching and aligning with the upper hardware receivers
a.
Attach the JAY FIT 2U Back to the hardware receivers by inserting left and right mounting
pins (F) in the left and right receivers (H).
b.
Locate the back to the approximate location, relative to both the chair and the user.
c.
Tighten bolts (I) on the inside of the mounting pin (F) to a torque of 11.3-12.4 Nm
[100-110 in-lbs].
d.
Tighten the bracket nuts (E). Torque to 8.5-9.6 Nm [75-85 in-lbs].
e.
Test the back release by pressing the release levers (G) forward and removing the
back off of the chair. Proper alignment of the mounting hardware and back is correct
when it is possible to have a smooth attachment and release of the back assembly. If
proper alignment has not been achieved, adjust the components until properly aligned.
f.
Once properly aligned, tighten the hardware receiver clamp screws (C). Torque to
8.5-9.6 Nm [75-85 in-lbs].
g.
Finish by inserting the locking pin (J) into the receiver.
5.
Attaching and aligning the lower hardware receivers
NOTE: Ensure the upper and lower brackets are aligned and parallel to the seat frame.
a.
Test the back release for the upper mounting hardware by pressing the release levers (G)
forward and removing the back from the chair. Proper alignment of the mounting hardware
and back can be determined by the smooth attachment and release of the back assembly.
If needed, continue small adjustments until the back can be attached and/or removed
smoothly.
b.
Loosen screws (L) to mount lower receivers on back canes (M).
c.
Using a 5/8-in wrench, loosen the nut (N) that secures the lower mounting pin (O) so that it
slides foreward and rearward.
d.
Slide lower receiver (P) up until it surrounds the lower mounting pin (O).
NOTE – Leave 1/8-in to 1/4-in of space between the bottom of the lower mounting pin (Q)
and the bottom of the lower receiver channel (R).
e.
Once properly aligned, tighten the hardware receiver clamp screws (L). The recommended
torque is 8.5-9.6 Nm [75-85 in-lbs]. Then tighten the lower mounting pin nut (N) and
torque to 11.3-12.4 Nm [100-110 in-lbs].
f.
Finish by inserting the locking pin (S) into the receiver. Function check, and complete
micro adjustments to height, depth, and angle.
6.
Attaching the back to the hardware receivers
Attach the JAY FIT 2U Back to the top and bottom mounting hardware receivers and push down
until the assembly is locked. There should be a "click" when locked properly. If needed, continue
small adjustments until the back can be attached and/or removed smoothly, and locks correctly
into the mounts. To make micro adjustments, loosen bolts (T) and (U). This will allow for minor
changes in height, depth, and angle. Retighten all bolts to required specs and test back function
and quick-release. Or, to make macro adjustments, loosen, but do not remove, bolts (C), (E), (I)
and (L), and nut (N). Position backrest to desired height, depth, and angle. Retighten all bolts
to required specs and test back function and quick-release.
