While the machine is working normally, the syntony of the ultrasonic wave and tank gives a well-proportioned sound with no shudder on the surface of the water but sprays generated by the tiny bubbles. If there are discontinuous surges, please add or reduce a little of washing solution in the tank to stop the surges, which is good for get a better cleaning effect. 2. Under the premise of ensuring that the cleaning objects are clean, work as intermittently as possible and not warm, because the warming and long-time ultrasonic work will increase the temperature inner of the chassis and accelerate the aging of the electronic components. 3. Never use flammable and corrosive detergents 4. When there is no proper cleaning solution in the cleaning tank, the heating and ultrasonic waves must not be turned on. 5. Prevent cleaning fluid and water from entering the chassis, soaking the circuit board and the vibrator, burning electrical components6. If any foreign object falls into the bottom of the tank, remove it immediately (do not take it directly by hand to prevent injury)
