possible solution
1. decrease the feed rate or workpiece pressure.
2. only cut wood and ensure moisture is below 20%.
3. straighten workpiece or use a different one.
4. adjust/calibrate fence (Page 37).
5. tension/replace V-belt (Page 60); ensure pulleys
are aligned.
6. test/repair/replace.
7. Wire motor correctly. refer to diagram inside junction
box or the wiring diagrams beginning on Page 69.
8. let cool, clean motor, and reduce workload.
9. test all legs for power, test field coil, and fix contacts
or replace if at fault.
10. adjust/replace centrifugal switch if available.
11. test for shorted windings, bad bearings and repair
or replace.
1. Carefully clean miter slot.
