2. Buffing wheel too large/wide.
3. Motor brushes at fault.
4. Motor overheated.
5. Circuit board at fault.
6. Motor or motor bearings at fault.
1. Use new buffing wheel; reduce feed rate.
2. Only use wheels rated for capabilities of machine.
3. Remove/replace brushes (
Page 24).
4. Clean motor, let cool, and reduce workload.
5. Inspect and replace if at fault.
6. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
Machine has
vibration or noisy
operation.
1. Buffing wheel loose or worn.
2. Tapered spindle sleeves dislodged.
3. Machine incorrectly mounted to workbench.
4. Motor or component loose.
5. Motor shaft bent.

Operation
Symptom
Possible Cause
Possible Solution
M
achine slows when
operating.
1. Operator using too much pressure.
2. RPM too low.
1. Use less pressure when buffing.
2. Increase buffing wheel RPM.
Poor results from
buffing/polishing
operation.
1. Workpiece contains residue or
contaminants.
2. Contaminated buffing compounds on
wheel.
3. Wrong buffing compound for material.
4. Workpiece not held firmly.
5. Incorrect stroke for buffing compound/
wheel/material.
6. Incorrect type of buffing wheel for material.
1. Dirt, oil, rust, paint, or other film must be removed
chemically or with water. Dry parts before buffing.
2. DO NOT mix different compounds on same wheel.
Use separate wheel for each compound. Remove
dried compound with buffing wheel rake (
Page 22).
3. Use correct buffing compound (
Page 19).
4. Use a holding device to firmly retain workpiece.
5. Use upward stroke with heavy pressure for cutting;
use downward stroke with light pressure for
polishing.
6. Use correct buffing wheel for material (
Page 18).
