During operation, first observe if the motor is rotating. Normally, the grinding sparks should be ejected towards the motor. If not, shut down the machine immediately and check if the circuit is functioning properly.

3. After the grinding wheel machine is started, it should be allowed to rotate smoothly before beginning the grinding process. If the machine is jumping significantly, it should be stopped and adjusted immediately.

Do not apply excessive force during grinding.

5. Select a grinding wheel that matches the spindle speed of the grinding machine according to the instructions provided.

6. New grinding wheels must have a factory-issued quality certificate or inspection mark. Do not use the wheel if any defects such as quality, hardness, grain size, or cracks in appearance are found before installation.

7. When installing the abrasive wheel, the gap between the inner hole of the wheel and the main shaft should not be too tight. It should be adjusted according to the technical requirements for loose fit, generally between 0.05 and 0.10 millimeters.
