Lateral Support Installation
1. Remove current stud plate using a 10mm wrench. Install new stud plate (D), two washers (B) and lateral
mount (C) on the inside of the back shell and three washers (B) and nuts (A) on the backside of the
back shell using a 10mm wrench.
2. Repeat on opposite side.
NOTE: Ensure the backrest height is set to desired height when reinstalling the new stud plate. Both
sides should be set to the same height.
NOTE: The lateral mount brackets (C) can be installed in the offset up or down positions and the
stud plate can be inverted for additional adjustment. The offset up configuration is considered the
default position.
3. Install lateral (D) on lateral mount with two bolts (A) and two washers (B) using a 4mm Allen wrench. If
additional adjustment is needed, the lateral and spacers can be changed. See notes in the figure above
and below.
NOTE: The addition or omission of the lateral spacer(s) (C) depends on the fit of the user in the
backrest. There are four spacer options - none, 1/4", 1/2" and 1/4" and 1/2" together. The 1/4" and
1/2" spacers are shown the figure below.

Headrest Installation
1. Attach headrest mounting bracket to predrilled mounting location using provided 6mm screws,
washers and nyloc nuts.
a. For Standard (Bottom Left Image) or Multi-Axis Removable Hardware (Bottom Right Image),
loosen the clamp by rotating the lever knob counterclockwise until the headrest can be moved
freely in the clamp. The headrest assembly can be temporarily adjusted higher or removed from
the back.
b. For POSALink Style Mounting Hardware, loosen the clamp by flipping the quick-release clamp
lever out and away from the clamp. This will allow the headrest to be temporarily adjusted higher
or removed from the clamp.
c. Reverse steps a. or b. to replace headrest in position on the Axiom Back.

Fitting Adjustments
WARNING: It may be possible to adjust the final position of the Axiom Back with an end user seated
in his wheelchair. This requires that the end user be able to sit in a stable position without the use of
the backrest. It may also be possible if there are people who can support the end user during
adjustment, this should be verified by a clinician trained to make that determination. Always make
sure the wheelchair wheel locks and anti-tips are set and locked. If these conditions cannot be met,
the end user should transfer from the wheelchair before making adjustments. Failure to take these
precautions may result in a fall and the potential for a serious injury.
1. Adjust the angle and depth of the backrest by loosening the two bolts on the bracket. Grab and
move/tilt the backrest assembly to desired position. Ensure both sides are set in the same scallop to
ensure identical positioning on both sides. Retighten hardware once desired configuration is achieved.
2. Adjust the height of the backrest by loosening the two bolts on the backrest bracket. Slide the shell up
or down to desired height and ensure bolts are set in the same Alignment Guide position to ensure
identical positioning on both sides. Retighten hardware once desired configuration is achieved.
3. Perform Check -
a. Tighten all fasteners completely and assure that the hardware does not move out of the adjusted
position under the load of the user.
b. Verify the back releases and latches easily.
c. Lift the backrest up by the strap and ensure it stays locked in.

Fitting Adjustments
WARNING: It may be possible to adjust the final position of the Axiom Back with an end user seated
in his wheelchair. This requires that the end user be able to sit in a stable position without the use of
the backrest. It may also be possible if there are people who can support the end user during
adjustment, this should be verified by a clinician trained to make that determination. Always make
sure the wheelchair wheel locks and anti-tips are set and locked. If these conditions cannot be met,
the end user should transfer from the wheelchair before making adjustments. Failure to take these
precautions may result in a fall and the potential for a serious injury.
1. To adjust the angle and depth of the backrest, loosen the pivot screw on the backrest bracket and
remove the angle adjustment screw. Grab and move/tilt the backrest assembly to desired position.
Align holes for desired backrest angle and reinstall the angle adjustment screw. Retighten the pivot
screw. Use the images and charts in General Setup Step 4 to identify screws and figure out the angle
configurations.
2. To adjust the backrest up or down, loosen the backrest bracket hardware (A) and move the assembly
up or down. If more range is needed, the hardware can be removed and reinstalled into the other
backrest bracket slots. Ensure both sides are set in the identical alignment guide positions in the
backrest bracket. Retighten hardware once desired configuration is achieved.
3. Perform Check -
a. Tighten all fasteners completely and assure that the hardware does not move out of the adjusted
position under the load of the user.
4. Install the back mount cover with one screw using a 5mm Allen wrench and repeat on opposite side.
See General Setup Step 8 for imagery if needed.
