However, it is a good practice to thoroughly check the machine for loose fasteners, handles, etc. before use. Controls Tailstock Handwheel (A, Fig. 1) - turn clockwise to move tailstock spindle forward. Turn counter-clockwise to retract tailstock spindle. Tailstock Spindle Lock (B, Fig. 1) - locks tailstock spindle. Release to adjust with handwheel. Tailstock Lock (C, Fig. 1) - locks tailstock in position on the bed. Release to move tailstock assembly closer to or farther from the headstock. Fig. 1 Nomenclature and Use Spur Center (A, Fig. 2) - locks into headstock and holds the workpiece during spindle turning. Face Plate (A, Fig. 3) - attaches to headstock and is used in face plate turning operations. Drift Rod (A, Fig. 4) - slides into the headstock to tap the spur center free. Stored in the hole in the base below the headstock. Tool Rest (Fig. 5) - attaches to the bed. Used to steady cutting tool during spindle turning or face plate operations. Adjusting the Tool Rest Position the tool rest as close to the work piece as possible. It should be 1/8" above the centerline of the work piece. Position the tool rest base on the bed by releasing the lock handle (A, Fig. 5) and sliding onto the desired position. Tighten handle (A, Fig. 5) to lock. Adjust the height of the tool rest by loosening handle (B, Fig. 5) and raising arm (C, Fig. 5). Should adjustment of the tool rest clamping device become necessary, turn off the machine, reach under the bed, and adjust the clamping nut. Changing Spindle Speeds 1. Disconnect the machine from the power source (unplug). 2. Open the access doors at the left side of the base (A, Fig. 6), and at the back side of the headstock (A, Fig. 7). 3. Loosen the motor plate lock handle (A, Fig. 8). Lift up on the motor plate handle (B, Fig. 8) to take tension off the belt. 4. Move the belt (B, Fig. 6) to the desired pulley groove according to the speed chart found on the inside of the headstock access door. Be sure the belt is aligned with spindle pulley and motor pulley. 5. Tension the belt by pushing down on the motor plate handle (B, Fig. 8) and lock in place. Belt Replacement 1. Disconnect the machine from the power source (unplug). 6. Open the access doors at the left side of the base (A, Fig. 6), and at the back side of the headstock (A, Fig. 7). 2. Loosen the motor plate lock handle (A, Fig. 8). Lift up on the motor plate handle (B, Fig. 8) to take tension off the belt. 3. Loosen the set screw (B, Fig. 7) on spindle pulley (upper). 4. Loosen two set screws in handwheel (C, Fig. 7). Unscrew the handwheel while holding onto the spindle. 5. Remove handwheel and pull the spindle out while holding onto the spindle pulley. 6. Place the new belt on the spindle pulley. Place the spindle pulley back into the headstock the same way it was removed. Fig. 8 7. Insert the spindle into the spindle pulley aligning the key. 8. Thread the handwheel onto the spindle leaving a little space between the handwheel and headstock. Tighten set screws. 9. Center the spindle pulley and tighten set screw. 10. Wrap the belt around the motor pulley (lower). Be sure the belt is aligned with spindle pulley and motor pulley. 11. Tension the belt and tighten the motor plate lock handle. Removing and Installing the Live Center Fig. 9 1. Loosen tailstock lock handle (B, Fig. 9). 2. Turn the tailstock handwheel (A, Fig. 9) counter-clockwise until the live center (C, Fig. 9) ejects from the spindle. 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.
