Adjusting Forks

NOTE: For this procedure, refer to FIGURE 10.4.
1. Remove the dust cover.
2. To properly tighten caster journal system and guard against flutter, perform the
following check:
A. Tip back the wheelchair.
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).
D. Adjust locknut according to freedom of caster swing.
3. Test wheelchair for maneuverability.
4. Readjust locknut if necessary, and repeat STEPS 2-3 until correct.
5. Snap dust cover into the caster headtube ensuring that the tabs are under the plastic
side shrouds.
NOTE: Components exploded for clarity. There is no need to remove the fork from the base frame.
