PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
Machine does not
start or a breaker
trips.
1. Emergency stop button depressed/at fault.
2. Incorrect power supply voltage or circuit size.
3. Motor overheated, causing thermal overload to
trip.
4. Power supply circuit breaker tripped or fuse
blown.
5. Motor wires connected incorrectly.
6. Wiring open/has high resistance.
7. Power switch at fault.
8. Centrifugal switch at fault.
9. Start capacitor at fault.
10. Thermal overload relay at fault.
11. Contactor not energized/has poor contacts.
12. Motor at fault.
1. Rotate button head to reset. Replace.
2. Ensure correct power supply voltage and circuit size.
3. Allow motor to cool, reset overload if necessary, and
reduce depth of cut. Contact Tech Support if relay
frequently trips.
4. Ensure circuit is sized correctly and free of shorts. Reset
circuit breaker or replace fuse.
5. Correct motor wiring connections.
6. Check/fix broken, disconnected, or corroded wires.
7. Replace switch.
8. Adjust/replace centrifugal switch if available.
9. Test/replace.
10. Replace.
11. Test all legs for power/replace.
12. Test/repair/replace.
Machine stalls or is
underpowered.
1. Machine undersized for task.
2. Workpiece not suitable for machine.
3. Motor overheated, causing thermal overload to
trip.
4. Belt(s) slipping; oil/grease on belt(s).
5. Dull knives/inserts.
6. Dust collection problem causing internal compo-
nents to clog up with shavings.
7. Motor wired incorrectly.
8. Centrifugal switch at fault.
9. Run capacitor at fault.
10. Pulley slipping on shaft.
11. Contactor not energized/has poor contacts.
12. Motor bearings at fault.
1. Reduce feed rate/depth of cut.
2. Only cut wood/ensure moisture is below 20%.
3. Allow motor to cool, reset overload if necessary, and
reduce depth of cut. Contact Tech Support if relay
frequently trips.
4. Clean/tension/replace belt(s); align pulleys (Page 38).
5. Sharpen/replace knives, or replace inserts (Page 28).
6. Clear blockages in dust chute/ducting, ensure dust col-
lector is operating efficiently.
7. Wire motor correctly.
8. Adjust/replace centrifugal switch if available.
9. Test/repair/replace.
10. Tighten loose pulley; replace pulley/shaft if damaged.
11. Test all legs for power/replace.
12. Test/repair/replace.
Machine has
vibration or noisy
operation.
1. Motor or component loose.
2. V-belt(s) worn or loose; belts slapping cover.
3. Pulley loose.
4. Bed rollers protruding unevenly.
5. Plastic chip deflector hitting knives.
6. Motor fan rubbing on fan cover.
7. Knives/gibs at fault.
8. Motor bearings at fault.
9. Cutterhead bearings at fault.
1. Inspect/tighten loose bolts/nuts; replace damaged com-
ponents.
2. Tension/replace belts as a matched set (Page 38).
3. Re-align/replace shaft, pulley set screw, and key.
4. Adjust bed rollers (Page 27).
5. Adjust chip deflector; replace if necessary.
6. Fix/replace fan cover; replace loose/damaged fan.
7. Sharpen/replace knives; set knife alignment/height cor-
rectly (Page 28).
8. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
9. Replace bearing(s).
