4 Process

5 Job Control

"a. Pay attention to safety in production. Before starting up, check the condition of the equipment and whether the timer and other components are functioning properly. When the equipment malfunctions, it should be shut down immediately

The power must be turned off when not in use or when leaving work. White mineral oil and other flammable substances must be stored in a sealed and separate manner.
