Machine does not start or a
breaker trips.

1. Emergency stop push-button is

engaged/faulty.

2. Power supply switched

OFF or is at

fault.

3. Blade guard limit switch engaged/

at fault.

4. Motor connection wired incorrect-

ly.

5.

Thermal overload relay has

tripped.

6. Wall fuse/circuit breaker is blown/

tripped.

7. Contactor not getting energized/

has burnt contacts.

8. Wiring is open/has high resistance.

9. Motor ON button or ON/OFF switch

is at fault.

10. Motor is at fault.

1. Rotate clockwise slightly until it pops out/replace

it.

2. Ensure power supply is switch on; ensure power sup-

ply has the correct voltage.

3. Move blade guard to the working position; replace

faulty limit switch.

4. Correct motor wiring connections.

5. Turn cut-out dial to increase working amps and push

the reset pin. Replace if tripped multiple times

(weak relay).

6. Ensure circuit size is suitable for this machine;

replace weak breaker.

7. Test for power on all legs and contactor operation.

Replace unit if faulty.

8. Check for broken wires or disconnected/corroded

connections, and repair/replace as necessary.

9. Replace faulty ON button or ON/OFF switch.

10. Test/repair/replace.

Machine stalls or is under-
powered.

1. Feed rate/cutting speed too fast

for task.

2. Workpiece material is not suitable

for this machine.

3. Belt(s) slipping.

4. Motor connection is wired incor-

rectly.

5. Motor bearings are at fault.

6. Start delay module is at fault.

7. Motor is at fault.

1. Decrease feed rate/cutting speed.

2. Only cut wood products; make sure moisture con-

tent is below 20% and there are no foreign materials

in the workpiece.

3. Replace bad belt(s), align pulleys, and re-tension.

4. Correct motor wiring connections.

5. Test by rotating shaft; rotational grinding/loose

shaft requires bearing replacement.

6. Adjust to correct delay; replace module.

7. Test/repair/replace.
