Adjusting the Height of the Caster
Tools Needed:
• 5/32” Allen Wrench
1. Loosen but do not remove the Allen screw. See Figure 13-10.
2. Raise or lower the swivel caster bullet to the desired height. For an inactive anti-tip, the bottom of the anti-tip
caster should be between 1-1/2” and 2” above the oor to ensure proper functionality. For an active anti-tip which
is in contact with the ground at all times, lower the caster to be level with the ground.
3. The active anti-tip caster will need to be squared using a drafting triangle or similar 90° angle tool as shown in
Figure 11-14. Rotate the fork until the at edge of the fork is perpendicular to the level surface. If the angle
needs to be adjusted please use the tools and follow the prodecures under “Center Mount Single Swivel Caster
Anti-Tip – Adjusting the Angle” on page 13-6.
4. Securely tighten the Allen screw.

chair. Apply sufcient pressure to ensure that the anti-tips are operating properly. If you ignore this Warning, you
may fall, tip over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair.
