Adjusting Toe-In/Toe-Out
Tools Needed:
• 3/16” Allen Wrench
• 7/8” Open End Wrench
• Ruler or Tape Measure
Note:
Adjusting toe-in/toe-out does not apply to chairs with 0° camber; however, it is still necessary to make sure that
the camber plug flats are perpendicular to the ground.
1. Make sure the distance from the end of the camber tube to the camber clamp is identical on both sides of the
chair. See Figure 8-4.
2. Make sure the rear wheels are properly inflated.
3. Place the chair on all four wheels with the casters trailing toward the rear of the frame. See Figure 8-5.

4. Measure from the floor to the center of the axle (“Measurement A”). Be sure the tape measure/ruler is
perpendicular to the floor.
5. Block the wheels with a heavy object so the chair can not roll forward or backward (do not use the wheel locks as
this may affect the toe-in/toe-out adjustment).
