1. Do not operate machinery without authorization without knowing the structure and function of weapons and equipment and the standard environment.
2. During the work process of machinery manufacturing, maintenance and physical models should not be carried out. Maintenance during equipment operation is very dangerous.
3. When mechanical equipment detects emergency leakage or other abnormalities (unreliable behavior, loud noise, vibration, etc.), it should be shut down immediately, the cause should be analyzed, and ideas should be eliminated. Work must not be carried out without failure.

5. It is strictly forbidden to operate beyond the maximum stroke of the roller. The minimum height of the grinding tools should not be less than 600mm.
6. The grounding device of the electrical equipment of the four-column hydraulic machine should be as firm and reliable as possible, and the grounding device cannot be connected to the electrical box incorrectly.
7. At the end of each day's quality work, the four-column hydraulic machine rollers should be placed in the lower position.
