continues to trip the breaker.
1. Start capacitor at fault
2. Motor connection wired wrong
3. Wiring at fault
4. Motor Start/Stop switch at fault
5. Motor at fault
6. Run capacitor at fault
7. Wall circuit breaker tripped or at fault
8. Power supply switched OFF or at fault
9. Plug/receptacle at fault or wired incorrectly
1. Test/replace if faulty.
2. Correct motor wiring connections.
3. Check/fix broken, disconnected, or corroded wires.
4. Replace switch.
5. Test/repair/replace.
6. Test/replace if faulty.
7. Ensure circuit size is correct/replace weak breaker.
8. Ensure power supply is on/has correct voltage.
9. Test wires and contacts; correct the wiring.
Machine is excessively loud
or
is experiencing
excessive
vibration.
1. Motor or component loose
2. Blade at fault
3. Motor mount loose/broken
4. Machine incorrectly mounted
5. Arbor pulley loose
6. Belts worn or loose
7. Pulley loose or at fault
8. Arbor bearings at fault
9. Motor bearings at fault
1. Inspect/replace damaged bolts/nuts, and re-tighten
with thread-locking fluid.
2. Replace warped/bent blade; re-sharpen dull blade.
3. Tighten/replace.
4. Tighten mounting bolts; relocate/shim machine.
5. Retighten/replace arbor pulley.
6. Adjust tension of/replace belt
7. Realign/replace shaft, pulley, setscrew, and key.
8. Replace arbor housing bearings; replace arbor.
9. Test by rotating shaft; grinding/loose shaft requires
bearing replacement.
Machine trips the
overload,
or feels
underpowered
during
operation.
1. Feed rate/cutting speed too fast
2. Workpiece material unsuitable for machine
3. Pulley/sprocket slipping on shaft
4. Motor bearings at fault
5. Contactor at fault
6. Motor overheated
7. Workpiece crooked; fence not aligned
8. Machine undersized for task; wrong blade
9. Run capacitor at fault
10. Belt is slipping from pulley
11. Motor wired incorrectly
12. Plug/receptacle at fault
13. Motor at fault
1. Decrease feed rate/cutting speed.
2. Only cut wood; ensure moisture is below 20%.
3. Replace loose pulley/shaft.
4. Test/repair/replace.
5. Test for good contacts/correct wiring.
6. Clean motor, let cool, and reduce workload.
7. Straighten or replace workpiece; adjust fence.
8. Use correct blade; reduce feed rate or depth of cut.
9. Test all legs for power/replace if faulty.
10. Adjust tension of/replace belt.
11. Test/repair/replace.
12. Wire motor correctly.
13. Test/repair/replace.
