Safety operating procedures

1. The plate rolling machine must be managed by a dedicated person.

2. The operator must be familiar with the structural performance and usage of the plate rolling machine, and can only operate it after the approval of the responsible manager.

3. Before starting the machine, carefully check whether the safety device is intact.

4. During operation, it is strictly forbidden to put hands and feet on the rollers, transmission parts and workpieces.

5. After the work is interrupted, the clutch should be put into neutral.

6. There must be a dedicated person to direct the collaborative work of multiple people.

7. Overload work is strictly prohibited.

8. The lifting and lowering of the upper roller, the tilting and resetting of the flip bearing and the balancing of the upper roller must be carried out after the main transmission is stopped.

9. It is forbidden to pile up workpieces and debris in the workplace, and the machine tool and the site must be kept clean at all times.

10. After the operation is completed, the power supply should be cut off and the power box should be locked
