3. Slide the camber plugs in or out of the axle sleeve mounts to increase or decrease the rear wheel spacing. Make
sure the distance from the end of the axle sleeve to the end of the axle sleeve mount is the same on both sides of
the chair.
4. Securely tighten all four Allen screws in the axle sleeve mounts.
5. Reinstall the rear wheels.
6. Check the toe-in/toe-out and adjust as needed.
Adjusting Toe-In/Toe-Out
Tools Needed:
• 3/16” Allen Wrench
• Ruler or Tape Measure
1. Make sure both rear wheels are equally spaced. See “Adjusting Rear Wheel Spacing” on page 8-7.
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 8-15.
4. Measure from the floor to the center of the axle (“Measurement A”). Be sure the tape measure/ruler is
perpendicular to the floor. See Figure 8-15.
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).
6. Measuring from the floor at the rear of each tire, mark the tire (with a felt tip pen) at the same height as
Measurement A.
7. Measuring from the floor at the front of each tire, mark the tire (with a felt tip pen) at the same height as
Measurement A.
8. Measure the distance between the left and right tires at the rear reference marks made in Step 6. See Figure
8-16.
9. Measure the distance between the left and right tires at the front reference marks made in Step 7.
