How should a feed grinder be inspected and repaired when it stops working?

First, check whether the power supply is normal, ensuring the socket is firmly connected, the switch is turned on, and the power supply is functioning properly. If the power supply is fine, then check whether the motor is abnormally overheating, whether the connecting wires are loose or damaged, and promptly replace or repair the faulty parts. At the same time, check the wear condition of the blades; if they are severely worn, replace them with new blades. Additionally, if the machine stops due to overload, check whether the feed amount is too large, and appropriately reduce the feed to lower the load. If none of the above methods work, it may be a malfunction of mechanical components, and it is recommended to have a professional conduct inspection and repair.
