How to troubleshoot a Central Machinery Grinder that will not start?
- K
  Kevin WagnerAug 2, 2025
  If your Central Machinery Grinder won't start, first ensure the power cord is properly connected. Then, check if the outlet has power. If not, check the circuit breaker, making sure the circuit's capacity matches the tool's requirements and isn't overloaded. Also, if your tool has a thermal reset breaker, turn it off, let it cool, and then press the reset button. If none of these steps work, the tool may have internal damage or wear, and you should have a technician service it.

Why is my Central Machinery 62501 overheating?
- W
  walterstimothyAug 9, 2025
  Your Central Machinery Grinder might be overheating because you are forcing it to work too fast; allow it to work at its own pace. It could also be due to a dull or damaged accessory, so keep cutting accessories sharp and replace them as needed. Another cause might be blocked motor housing vents; wear ANSI-approved safety goggles and a NIOSH-approved dust mask/respirator while blowing dust out of the motor using compressed air. Finally, the motor might be strained by a long or small diameter extension cord; eliminate the use of an extension cord, or if one is needed, use one with the proper diameter for its length and load.

  moranangelaAug 14, 2025
  If your Central Machinery Grinder's performance decreases over time, it could be due to a dull or damaged accessory. Keep cutting accessories sharp and replace them as needed. Alternatively, the carbon brushes may be worn or damaged, in which case you should have a qualified technician replace them.

Why does my Central Machinery Grinder operate slowly?
- T
  Tonya ChanAug 20, 2025
  If your Central Machinery Grinder is operating slowly, the extension cord might be too long or the wire size too small. Try eliminating the use of an extension cord. If an extension cord is necessary, use one with the proper diameter for its length and load.

  Ashley MercadoAug 26, 2025
  If your Central Machinery Grinder is making excessive noise or rattling, it may have internal damage or wear, such as with the carbon brushes or bearings. Have a technician service the tool.
