Replacing the front castors
If necessary, the front castor can be replaced:
•
Completely unscrew one of the “D” screws and
remove the “E” pin being careful to where the “F”
spacers are;
•
If necessary, change the wheel;
•
Position the wheel hub align with the most suitable
fork hole;
•
Insert the “E” pin, being careful to keep the “F”
spacers in their original sequence;
•
Fix properly the “D” screw.
Be sure to choose the same position for both castors. Asymmetrical combinations
produce instability.
Be careful not to change the front seat height while changing the front castors
because this will modify the perpendicularity to the ground of the front fork roataing
axle.
