Loosely assemble the clamps onto the back canes at the
desired location talked about in step 3. Bolts should thread
inwards from the outside of the chair. Tighten clamp enough
so it stays in place and repeat on opposite side.
Use a level and a tape measure to ensure the clamps are
level and the distance from backcane to clamp mount is 1/2”.

Adjust the depth and angle by moving the backrest assembly
to the desired positions. With position determined, ensure
the bolts are secured in the same scallop on the bracket on
both sides of the chair.
Hold the backrest shell against the chair at approximate height
desired. Find a back cane location that can accomodate the
clamp near the center of the slots on the backrest bracket.
Typically the backrest will rest 1-2” above the cushion.
Ensure same
scallop is used
on both sides of
chair
Perform Check, see Check Section in next section.
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.
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.
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.

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.
