Figure 124. Clutch adjustment overview.
DO NOT rotate the spindle or input pulley while any body part is inside the headstock. Doing so may cause entanglement and serious crushing injuries.
Clutch components get hot during operation. To avoid burn injuries, wear heavy leather gloves or allow components to cool before service.
7.Use a metal scribe or permanent marker to mark the position of the adjustment ring relative to its clutch assembly, then use a small screwdriver to pry and slide the necessary adjustment ring away from its corresponding clutch to unlock it (see Figure 125).
