Operators of vacuum tumbling machines must undergo training before taking up their posts. In the event of sudden malfunctions or other temporary issues during operation, they must not disassemble or assemble the machine without authorization. Instead, they must seek on-site guidance from professionals or entrust the task to professional staff to ensure safety. When using the vacuum tumbling machine, the following safety procedures should be observed:

1. Feeding the rolling and kneading machine: Turn on the vacuum pump and connect the suction tube to the material when a certain negative pressure is reached. Use the vacuum pump to evacuate and maintain the vacuum level.

2. Control the operation time: The dedicated time setting button on the vacuum roller can be adjusted according to different needs, maximizing its efficiency.

3. We can set the rolling time by adjusting the scroll time on the control panel. The intermittent time during the production of the rolling machine can be customized according to different needs. The intermittent time and working time are set separately, with independent time control buttons for each.

4. Turn the knob on the control panel to "Run", and turn the vacuum pump and inflation knob to "On". The machine will start running according to the set mode.

In addition, to stop the vacuum tumbling machine after work, simply rotate the knob on the control panel to the stop position. If a working time has been set, the machine will automatically stop running after the working time is up.
