Installing the Back
1. Verify that the overall fit and alignment of the back
is correct (make adjustments as needed).
2. Fully secure the cane clamp screws onto both
back posts, and tighten the set screws to ensure
the mounting plates do not slip or rotate.
3. To best determine the optimal depth & recline
settings for the back, the user should be seated in
the wheelchair. While seated, loosen the
depth/recline screws on the mounting plates and
adjust the back to the desired depth and recline
angle. Re-tighten all screws to lock the back in
position.
 Ensure that the depth/recline
adjustment for the back is made
symmetrically* on the left & right
mounting plates.
The vertical score lines on the mounting
plates are designed as a point of
reference to assist with symmetrical
mounting (see image). Since the back
can be mounted in a rotated (reclined)
position if desired, it will not always be
mounted parallel with these vertical
lines.
