The precautions for stopping the film blowing machine are as follows:

1. Close the hopper gate, and produce normally until there is no material in the barrel or manually operate the empty injection.

2. Turn all switches to the "off" position. When stopping the last shift on holidays, turn off the main power switch of the machine tool.

3. Clean the machine tool, workbench and ground debris, oil stains and dust to keep the workplace clean and tidy.
