Daily maintenance and methods

I. Use the principles of: 1 see, 2 listen, 3 workmanship.

1. Check whether the wire, switch, and machine are normal. If there is any abnormality, don't turn it on, and then turn it on after handling.

2. After closing, listen to the machine's running sound, is it normal? If there is abnormal sound or noise, stop and call the machine immediately

Restart the machine after repairing and checking.

3. Look at normal and work with no noise. When people leave during work, they must stop and leave for more than two minutes.
