  If your Hercules Grinder won't start, there are several potential causes. First, ensure the power cord is properly plugged in. Next, check the power outlet to confirm it's working. If the outlet is unpowered, turn off the tool and inspect the circuit breaker; if tripped, ensure the circuit has sufficient capacity and no other loads. If your tool has a thermal reset breaker, turn it off, let it cool, and then press the reset button. Finally, internal damage or wear could be the issue, in which case you should have a technician service the tool.

  Several factors can cause your Hercules Grinder to overheat. You might be forcing the tool to work too fast; allow it to work at its own pace. The motor housing vents could be blocked; wear safety goggles and a dust mask/respirator while using compressed air to blow out any dust. Also, a long or small diameter extension cord could be straining the motor; try eliminating the extension cord or using one with the correct diameter for its length and load.

  Your Hercules Grinder might be operating slowly due to a couple of reasons. You could be applying excess pressure to the workpiece; decrease the pressure and allow the tool to do the work. Alternatively, a long or small diameter extension cord might be reducing power; eliminate the extension cord or use one with the proper diameter for its length and load.

  If your Hercules Grinder isn't grinding, sanding, or brushing effectively, it could be due to a couple of reasons. The disc accessory might be loose on the spindle; ensure the disc accessory is the correct dimension and the Flange Arbor Nut is tight. Also, the disc accessory might be damaged, worn, or the wrong type for the material; check its condition and type, and use only the proper type of disc accessory in good condition.
