PROBLEM
POSSIBLE.CAUSE
CORRECTIVE.ACTION
Bad surface
finish.
1. Spindle speed wrong.
2. Dull tooling or wrong tool selection.
3. Tool height not at spindle centerline.
4. Belt bad.
1. Adjust for appropriate spindle speed.
2. Sharpen tooling or select a better tool for intended
operation.
3. Adjust tool rest so tool is even with spindle center-
line.
4. Replace belt.
Excessive
vibration upon
startup (when
workpiece is
installed).
1. Workpiece is mounted incorrectly.
2. Workpiece warped, out of round, or flawed.
3. Spindle speed too fast for workpiece.
4. Workpiece hitting stationary object.
5. Headstock, tailstock, or tool rest not securely
clamped to lathe bed.
6. Belt pulleys are not properly aligned.
7. Lathe resting on an uneven surface.
8. Motor mount bolts loose.
9. Belt worn or damaged.
10. Spindle bearings worn or damaged.
1. Remount workpiece, making sure that centers are
embedded in true center of workpiece.
2. Cut workpiece to correct, or use different
workpiece.
3. Reduce spindle speed
(Page 35).
4. Stop lathe and fix interference problem.
5. Check clamp levers and tighten if necessary (
Pages
29–30).
6. Align belt pulleys
(Page 49).
7. Shim stand or adjust feet to eliminate wobbles.
8. Tighten motor mount bolts.
9. Replace belt
(Page 48).
10. Test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.

or dig into
workpiece.
1. Wrong chisel/tool is being used.
2. Chisel/tool dull.
3. Tool rest set too low.
4. Tool rest set too far from workpiece.
