Troubleshooting
Motor & Electrical
Symptom
Possible Cause
Possible Solution
Machine does not
start or a breaker
trips.
1. Power switch key is removed or in locked
position.
2. STOP button is engaged/faulty.
3. One of the door switches is at fault.
4. Plug/receptacle is at fault or wired
incorrectly.
5. Motor connection wired incorrectly.
6. Wall fuse/circuit breaker is blown/tripped.
7. Power supply switched OFF or is at fault.
8. Wiring is open/has high resistance.
9. START button is at fault.
10. Motor is at fault.
1. Install power switch key and turn it to the unlocked
position.
2. Rotate clockwise until it pops out; replace it if faulty.
3. Check/replace door switch.
4. Test for good contacts; correct the wiring.
5. Correct motor wiring connections (
Page 55).
6. Ensure circuit size is suitable for this machine;
replace weak breaker.
7. Ensure power supply is switched
ON; ensure power
supply has the correct voltage.
8. Check for broken wires or disconnected/corroded
connections, and repair/replace as necessary.
9. Replace START switch.
10. Test/repair/replace.
Machine stalls or is
overloaded.
1. Operator feeding workpiece too fast.
2. Workpiece alignment is poor.
3. Wrong workpiece material or blade.
4. Blade is slipping on wheels.
5. Motor has overheated.
6. V-belt(s) slipping.
7. Machine is undersized for the task.
8. Pulley slipping on shaft (other than variable
speed pulleys).
9. Motor bearings are at fault.
10. Motor is at fault.
1. Reduce feed rate; increase blade speed.
2. Eliminate workpiece binding; use jig, fence, guide,
clamps, roller table, or push blocks as required for
workpiece alignment control.
3. Use metal with correct properties for your type
of machining; match blade with workpiece and
operation.
4. Adjust blade tension and tracking (
Page 19); redress
rubber wheel tires if necessary (
Page 41).
5. Clean off motor, let cool, and reduce workload.
6. Replace bad V-belt(s) (
Page 46).
7. Use sharp blade with lower TPI; reduce the feed
rate; use a small amount of oil-based coolant if
necessary.
8. Replace loose pulley/shaft.
9. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
10. Test/repair/replace.
