Regarding the precautions for the use of ultrasonic cleaning machine equipment, the following issues need to be noted. 1. The power supply for the ultrasonic generator should be a separate 220V/50Hz power line and be equipped with a voltage stabilizer of 2000W or more. 2. The bottom of the cleaning tank should be regularly flushed to ensure there is no excessive debris or dirt. 3. Each time when changing the liquid, wait until the ultrasonic wave is activated before washing the items. 4. The power supply of the ultrasonic cleaner and the electric heater must have a good grounding device. 5. The ultrasonic cleaner must not be started without cleaning solution. That is, the ultrasonic switch must not be turned on if a certain amount of cleaning solution has not been added to the cleaning tank. 6. For cleaning equipment with heating devices, it is strictly prohibited to turn on the heating switch when there is no liquid. 7. Do not strike the bottom of the cleaning tank with heavy objects (iron parts) to avoid damaging the energy converter chips. Everyone should pay more attention when using the cleaning machine equipment.
