Solution
1. Remove and re-install, as instructed on Page 25.
2. Clean tool and spindle taper.
3. Reduce depth of cut and allow chips to clear.
4. Properly tension V-belts.
5. Correct voltage.
1. Tighten table locks (Page 27).
2. Properly clamp workpiece on table or in vise.
3. Set spindle speed correctly (Page 22) or use
slower feed rate.
4. Fully retract spindle and lower headstock. This
increases rigidity to decrease vibration.
5. Tighten quill lock lever.
1. Loosen/replace lock nuts.
2. Fix/replace broken or loose parts; clean and
lubricate rack and pinion.
1. Set spindle speed correctly (Page 22).
2. Sharpen cutting tool or select one that better suits
the operation.
3. Check for proper cutting tool rotation.
4. Properly clamp workpiece on table or in vise.
5. Fully retract spindle and lower headstock. This
increases rigidity.
1. Allow drill to cool.
1. Increase return spring tension (Page 35).
2. Replace return spring.
1. Calibrate depth stop (Page 36).
