IX. DEALER SERVICE AND ADJUSTMENT
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 aff ects 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 (A) (2 per side) that secure the camber tube clamp. Observe the ball in the
level (C), and rotate the camber tube (B) until the ball is centered in the level. The toe is now set at
zero.
Before tightening the screws (A), make certain that the camber tube is centered left-to-right relative
to the wheelchair frame. The end of the camber tube should be fl ush with the outer most portion of
the camber tube clamp. Torque fasteners (A) to 62 in-lbs. (7 Nm).
5. Setting the Toe to Zero– Alternative Method
Place the entire wheelchair on a fl at horizontal table or ground surface. Loosen the 4 cap screws (A)
(2 per side) that secure the camber tube clamp. Locate the fl at surfaces 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 fl at horizontal surface and up against the fl at of
the camber plug. Rotate the camber tube and plug assembly until the fl at surface of the camber plug
is parallel to the measuring tool.
Before tightening the screws (A), make certain that the camber tube is centered left-to-right relative
to the wheelchair frame. The end of the camber tube should be fl ush with the outer most portion of
the camber tube clamp. Torque the fasteners to 62 in-lbs. (7 Nm).
