  If your Hercules Grinder won't start, there are several potential causes. First, ensure the power cord is properly plugged in. Second, check if the outlet has power; if not, check the circuit breaker, ensuring it's the correct capacity and not overloaded. Third, if your tool has a thermal reset breaker, turn it off, let it cool, and then press the reset button. Lastly, internal damage or wear could be the issue, in which case you should have a technician service the tool.

Why is my Hercules HE61S Grinder overheating?
- D
  Dawn AndersonAug 9, 2025
  If your Hercules Grinder is overheating, there are a few things to check. First, avoid forcing the tool to work too fast; let it work at its own pace. Second, ensure the motor housing vents are not blocked. Wear ANSI-approved safety goggles and a NIOSH-approved dust mask/respirator while blowing out any dust using compressed air. Finally, a long or small diameter extension cord might be straining the motor. Try eliminating the extension cord or using one with the correct diameter for its length and load.

  Adrienne ColemanAug 14, 2025
  If your Hercules Grinder is operating slowly, it might be due to excessive pressure being applied to the workpiece. Decrease the pressure and allow the tool to do the work. Also, a long or small diameter extension cord could be reducing power. Try eliminating the extension cord, or if one is necessary, use the proper diameter for its length and load.
