5. Centrifugal switch is at fault.
6. Motor is at fault.
1. Only drill wood products; make sure moisture
content is below 20% and use sharp bits/reduce
feed pressure.
2. Correct motor wiring connections (
Page 39).
3. Straighten or replace workpiece/adjust hold-down
clamp pressure (
Page 24).
4. Clean off motor, let cool, and reduce workload.
