section of the manual.

6. Remove the toe adjustment rings from the existing axle tube.
7. Pull the existing axle tube through the other camber clamp and remove from the
wheelchair.

notches in the axle tube are towards the rear of the wheelchair and the slots in the
axle tube are facing up.

toe adjustment rings are facing towards the outside of the wheelchair.

tube is flush with the outside of the camber clamp.

tube to the camber clamps at this time.
WARNING
NEVER position the camber inserts in the axle tube with more than 3-
inches (12 indexing marks showing) of the camber insert outside of the
axle tube. Otherwise, the camber inserts will not be securely tightened in
the axle tube resulting in possible injury to the user or damage to the
wheelchair.

camber inserts to the position noted in STEP 1. Make sure there are no more than
3-inches (12 indexing marks) of the camber inserts outside of the axle tube.

NOTE: To maximize rollability: Before using the wheelchair, make sure both camber inserts are
set to the same indexing notch. This will make sure the distance between the rear wheel and the
wheelchair is the same on both sides.

manual.
NOTE: The performance of the wheelchair will be affected if the axle tube has not been adjusted
to correct the toe in/toe out of the wheelchair.
