Additional Information
It is advisable to make a preliminary run of the freewheel to eliminate excess grease from the mechanism and ensure the correct settling of the pawls. This process can be accelerated by introducing a little oil in the groove between the center of the freewheel and the teeth.
If the freewheel is used for trial without having set the palws first, it will not work properly and will cause it to jump, damaging the slot and the pawl.
