Abnormal cutting disc movement

"1. Turn off the power to the equipment, remove the cutting deck, and check whether it is entangled with weeds or other foreign objects, or if any stones are stuck. If so, clean it thoroughly before testing; or check for rust. We recommend that users thoroughly clean the cutting deck and blades after each use. If rust or corrosion is found, replace them as soon as possible.
2. If there are no foreign objects or hardware malfunctions, restart the equipment. If the problem persists, send it in for repair or request a replacement."
