Ⅳ the moisture content of the materials to be processed shall be controlled below 15%. When feeding, shake the grass with a fork and then feed it, so as to prevent the damage of machine parts caused by iron blocks and stones sandwiched in the materials.
V. regularly inspect the parts of the crusher. If the lubricating grease in the bearing hardens and deteriorates, clean it with clean kerosene or diesel oil and inject new grease (No. 3 or No. 4 calcium base grease).

The tools shall not be placed on the machine or material pile. If the machine is found to be in abnormal sound, discharge blockage, bearing or motor overheating, it shall be stopped immediately and restarted after troubleshooting.
6. Do not stop the machine immediately after filling the materials, but idle for another 2-3 minutes to remove the residues in the machine.
