  If your Hercules Grinder does not grind, sand, or brush effectively, consider the following: 1. The disc accessory may be loose on the spindle. Ensure the disc accessory is the correct dimension and the flange arbor nut is tight. 2. The disc accessory may be damaged, worn, or the wrong type for the material. Check the condition and type of disc accessory and use only the proper type in good condition.

  If your Hercules Grinder won't start, there are several potential causes: 1. The cord may not be properly connected. Ensure it's securely plugged in. 2. There might be no power at the outlet. Check the outlet and, if it's unpowered, check the circuit breaker. If the breaker is tripped, ensure the circuit has the correct capacity for the tool and isn't overloaded. 3. The tool's thermal reset breaker might have tripped. Turn off the tool, let it cool down, and then press the reset button on the tool. 4. There could be internal damage or wear. In this case, have a qualified technician service the Hercules Grinder.

  If your Hercules Grinder is overheating, consider the following: 1. You might be forcing the tool to work too fast. Allow the tool to work at its own pace. 2. The motor housing vents could be blocked. Wear ANSI-approved safety goggles and a NIOSH-approved dust mask/respirator while using compressed air to blow dust out of the motor. 3. The motor might be strained by a long or small diameter extension cord. Try eliminating the extension cord. If you need one, use the correct diameter for its length and load.

  If your Hercules Grinder operates slowly, it might be due to: 1. Excessive pressure being applied to the workpiece. Decrease the pressure and allow the tool to do the work. 2. Power reduction caused by a long or small diameter extension cord. Eliminate the use of an extension cord, or use one with the proper diameter for its length and load.
