WARNING
When repositioning the camber clamps on the CG Brackets, always leave as many open holes between the two Allen
screws as your desired placement will permit. NEVER use two adjacent holes to attach the camber clamps to the CG
Brackets.
If you ignore this Warning, your camber clamp may fail, causing you to fall, tip over or lose control of the
chair and seriously injure yourself or others or damage the chair.
Tools Needed:
• 5/32” Allen Wrench
• Ruler
1. Remove the rear wheels.
2. Remove the four Allen screws (two on each side) that secure the camber clamps to the CG brackets. See Figure

3. Reposition the camber clamps to the desired position on the CG Brackets, making sure the positioning is identical
on both sides of the chair. You MUST leave one open hole between the two Allen screws.
4. Reinstall the Allen screws and lock washers and securely tighten all four Allen screws.
5. Reinstall the rear wheels.
6. Check the toe-in/toe-out and adjust as needed. See pages 8-8 and 8-9.
