11.2 Adjusting Front Castors
1. Remove the headtube cover from the castor headtube.
2. To properly tighten castor journal system and guard against
flutter, perform the following check:
• Tip back the wheelchair to floor.
• Pivot both forks and castors to top of their arc simultane-
ously.
• Let castors drop to bottom of arc (wheels should swing
once to one-side, then immediately rest in a straight
downward position).
• Adjust locknuts according to freedom of castor swing.
3. Test wheelchair for manoeuvrability.
4. Readjust locknuts if necessary, and repeat STEPS 1-3 until
correct.
5. Snap headtube cover into the castor headtube.
NOTE:
Motor lock disengagement/engagement allows free wheeling or joystick controlled operation. Free
wheeling allows an assistant to manoeuvre the wheelchair without power.
