Why won't my Central Machinery 37822 Grinder start?
- M
  Melissa MooreJul 30, 2025
  There are several reasons why your Central Machinery Grinder might not start: 1. The power cord may not be connected. Ensure the cord is properly plugged into an outlet. 2. There may be no power at the outlet. Check the outlet for power. If there's no power, turn off the grinder and check the circuit breaker. If the breaker is tripped, ensure the circuit has sufficient capacity for the grinder and isn't overloaded with other devices. 3. The grinder's thermal reset breaker might have tripped (if equipped). Turn off the grinder, let it cool down, and then press the reset button on the tool. 4. There could be internal damage or wear, such as with the carbon brushes or switch. In this case, have a qualified technician service the grinder.

What to do if my Central Machinery 37822 is overheating?

  Matthew MccarthyAug 5, 2025
  If your Central Machinery Grinder is overheating, consider the following: 1. You might be forcing the grinder to work too fast. Allow the machine 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. A long or small diameter extension cord may be straining the motor. Eliminate the use of an extension cord, or if one is necessary, use a cord with the correct diameter for its length and the load.

  If your Central Machinery Grinder is operating slowly, the power may be reduced by using a long or small diameter extension cord. Try eliminating the extension cord. If you must use one, make sure it has the proper diameter for its length and the load. Refer to the Extension Cords section in the GROUNDING section for more information.
