(Figure 11).

take tension off the belt.
4. Loosen the set screw (B, Figure 11) on spindle pulley (upper).

spindle.
6. Remove handwheel and pull the spindle out while holding onto the spindle pulley.
7. Place the new belt on the spindle pulley. Place the spindle pulley back into the headstock the same
way it was removed.

Removing and Installing Live Center
1. Loosen tailstock lock handle (B, Figure 13).
2. Turn the tailstock handwheel (A, Figure 13) counter-clockwise until the live center (C, Figure 13) ejects
from the spindle. NOTE: Hold the live center in your other hand to prevent it from falling.
3. Before installing the live center into the spindle, the spindle must be extended out from the tailstock
body far enough to allow the live center to “seat” in the spindle.
