    How to troubleshoot a Central Machinery 68147 that will not start?

      Terri LaraJul 31, 2025
      If your Central Machinery Power Hammer won't start, first ensure the power cord is properly connected. Then, check the outlet for power; if there's no power, turn off the tool and inspect the circuit breaker, ensuring it's the correct capacity and not overloaded. Also, if your tool has a thermal reset breaker, turn it off, let it cool, and press the reset button. If none of these steps work, internal damage or wear may be the cause, and a technician should service the tool.

    Why is my Central Machinery 68147 Power Hammer overheating?
    • M
      Michelle RamseyAug 6, 2025
      Your Central Machinery Power Hammer might be overheating because you are forcing it to work too fast; allow the tool to work at its own pace. Also, check if the cutting accessories are dull or damaged, and sharpen or replace them as needed. Make sure the motor housing vents are not blocked; wear safety goggles and a dust mask/respirator while using compressed air to blow out any dust. Finally, the motor might be strained by a long or small diameter extension cord; eliminate the extension cord or use one with the proper diameter for its length and load.

      If your Central Machinery Power Hammer's performance decreases over time, make sure that cutting accessories are sharp, and replace them if needed. If the internal lubrication is cold, allow the tool to operate without any load for about 5 minutes before use. If these steps do not help, the carbon brushes may be worn or damaged, and a qualified technician should replace them.

      Anthony JohnsonAug 18, 2025
      If your Central Machinery Power Hammer operates slowly, the extension cord may be too long or the wire size may be too small. Try eliminating the extension cord. If an extension cord is necessary, use a shorter or heavier gauge cord.
