2. Wheel Camber
Wheel camber, shown as angular relationship (A), 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 han-
drims.
Wheel camber is determined by pairs of interchangeable camber plugs which are available from your authorized
supplier in 0º, 3°, and 6º angles.
3. 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 3° and 6° camber plugs.
Toe refers to how well the rear wheels of the chair are aligned relative to the ground. It affects how well the chair
will roll. Drag or rolling resistance is optimally minimized when the wheel toe is set to zero.
4. Setting the Toe to Zero
Loosen the 4 cap screws (B) (2 per side) that secure the camber tube clamp. Observe the ball in the level (C), and
rotate the camber tube (D) until the ball is centered in the level. The toe is now set at zero.
Before tightening the screws (B), make certain that the camber tube is centered left-to-right relative to the
wheelchair frame. The end of the camber tube should be flush with the outer most portion of the camber tube
clamp. Torque fasteners (B) to 62 in-lbs. (7 Nm).
5. Setting the Toe to Zero– Alternative Method
Place the entire wheelchair on a flat horizontal table or ground surface. Loosen the 4 cap screws (B) (2 per side)
that secure the camber tube clamp. Locate the flat surfaces on the front and rear of the camber plugs (E). 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 assem-
bly until the flat surface of the camber plug is parallel to the measuring tool.
Before tightening the screws (B), make certain that the camber tube is centered left-to-right relative to the
wheelchair frame. The end of the camber tube should be flush with the outer most portion of the camber tube
clamp. Torque the fasteners to 62 in-lbs. (7 Nm).
