1. Check for caster squareness
Your Breezy wheelchair leaves the factory with the casters adjusted square. Any time you change your wheel-
chair rear axle height, rear tire size, or center of gravity position, you should check that the casters are still
square. A caster that is not square will result in the caster lifting off the floor as it rotates around the stem bolt
and may also lift the front of the wheelchair up and down. Check for squareness by placing your wheelchair on
a flat, horizontal surface. Rotate both forks so that the casters are towards the rear of the wheelchair. Place a
square or pocket level against the flat surface on the rear of the fork and note whether this surface is vertical
(square) . If this surface is more than 2 degrees away from vertical, your casters require re-squaring.
2. Caster journal angle adjustment
a. Loosen the hardware so the the eccentric nuts(D) can be adjusted.
b. Move the caster so that it is square.
c. Make sure the eccentric nuts are seated correctly. Tighen the hardware to a torque of 75 in-lbs.
