1. Caster flutter is when a wheelchair is pushed the casters wobble side to side.

2. Remove the dust cap to access the fork nut.

3. Tighten the fork nut slightly and push the chair with some in it. If the caster flutter is still present repeat the tightening until the caster flutter is eliminated. If the nut is tightened too much so that the caster does not swivel, loosen the nut slightly. Replace the dust cap.
