4. Wheel Camber
Wheel camber, shown as angular relationship (H), provides greater side-to-side stability due to the
increased width and angle of the wheelbase. It also allows for quicker turning and greater access to the
top of the handrims.
Wheel camber is determined by pairs of interchangeable camber plugs which are available from your
authorized supplier in 0º, 2°, and 4º angles.
5. Setting Toe-in Toe-out to Zero
NOTE– A wheelchair equipped with 0° camber plugs cannot have a toe-in toe-out condition.
This adjustment is only required when using 2° and 4° camber plugs.
Toe refers to how well the rear wheels of the chair are aligned relative to the ground
well the chair will roll. Drag or rolling resistance is optimally minimized when the wheel toe is set to zero.
Setting the Toe to Zero
Safely place the entire wheelchair on a flat horizontal table or ground surface. Starting on one side,
remove rear wheel, and loosen the 2 screws (A) that secure the camber tube clamp. Locate the flat sur-
faces on the front and rear of the camber plugs (D). Place an object that is known to have an accurate
90° corner (such as a carpenters square, drafting triangle, etc.) down on the flat horizontal surface and
up against the flat of the camber plug. Rotate the camber tube and plug assembly until the flat surface of
the camber plug is parallel to the vertical edge of the measuring tool.
Once square, tighten screws (A), and place rear wheel securely back in place. Repeat process for
opposite side.
Before tightening the screws (A), make certain that the camber tube is centered left-to-right relative to
the wheelchair frame. There should be an equal gap on both sides of the wheelchair (see section P: Rear
Wheel Spacing).
Tighten the fasteners to 144 in-lbs. (16.3 Nm).
