When the ultrasonic is in normal operation, the uniform sound of the ultrasonic and the tank body should be heard, and the surface of the cleaning liquid is not excited. Only the ripple caused by the hole blasting, if there is intermittent oscillation, please add a little cleaning liquid or discharge a little cleaning liquid. Eliminate the oscillations and help to clean the objects2. 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 detergents4. When there is no proper cleaning solution in the cleaning tank, the heating and ultrasonic waves must not be turned on.
