WARNING
NEVER position the camber inserts in 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.

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

ING/CLOSING CLAMPS in this procedure of the manual.
