12.1 Adjusting Fork Tension
1. To properly tighten forks and guard against flutter, perform the following check on both forks:
A. Tip back the wheelchair to floor.
B. Pivot both forks and casters to top of their arc simultaneously.
C. Let casters drop to bottom of arc (wheels should swing once to one-side, then IMMEDIATELY rest in a straight downward position).
2. If necessary, perform one of the following to adjust the fork tension:
• Standard Forks - Adjust locknut according to freedom of caster swing (Detail “A”).
a. Tighten locknut to reduce caster swing.
b. Loosen the locknut to increase caster swing.
• One Sided Fork (Detail “B”)
a. No tension adjustment can be performed on this fork.
3. Test wheelchair for maneuverability.
4. If necessary, repeat STEPS 1-2 to adjust locknuts until tension is correct for both forks.
WARNING
After any adjustments, repair or service and before use, make sure all attaching hardware is tightened securely - otherwise
