When cleaning the vibration engraving machine, the following precautions should be taken:

1. Turn off the power: Before cleaning, be sure to turn off the power of the vibration engraving machine to ensure safety.

2. Use a damp cloth: Wipe the surface of the machine with a damp cloth to remove dust and dirt. Avoid using chemical cleaners as they may cause damage to the machine.

3. Cleaning tools: If there is dust or dirt on the tools, clean them with a clean cloth or brush. Avoid using water or cleaning agents to directly clean the tools, as this may cause rusting or damage to the tools.

4. Cleaning the vacuum cleaner: If the vibration engraving machine is equipped with a vacuum cleaner, the filter and pipes of the vacuum cleaner should be cleaned regularly to ensure its normal operation.

5. Keep dry: After cleaning, ensure that the machine and tools are completely dry to prevent rust and corrosion.

The above are the precautions to be taken when cleaning a vibration engraving machine. The correct cleaning method can extend the service life of the machine and improve work efficiency.
