Microscopic bubbles are formed, and then implode violently causing the cavitation which create an intense scrubbing action on the surface of the item being cleaned. Bubbles are small enough to penetrate microscopic crevices, cleaning them thoroughly and consistently.Q: Which products can I clean this model?A: Many products can be cleaned, such as glasses, necklaces, earrings, bracelets, electronics, watches, dentures, printer ink heads, shaver heads, nibs, coins, badges, pacifiers, etc.Q: Which washing aid can be properly added for better cleaning during the cleaning process?A: You can add cleaning liquid or detergent, such as: dishwashing liquid, soapy water, disinfectant, etc. However, do not add acid or alkaline solution, prevent ABS corrosion damage.Q: Common products have 40HZ or 33HZ. What is the difference between these two frequencies?A: These products are divided into high frequency and low frequency. Generally, the high frequency has 40HZ and 42HZ, and the low frequency generally has 28HZ and 33HZ. The higher the frequency, the larger the number of bubbles generated, the smaller the bubbles, and the better the cleaning effect for some blind holes; the lower the frequency, the smaller the number of bubbles generated and the larger the bubbles, which is suitable for cleaning large surfaces. Products with both frequencies can be better cleaned.Package List:1 x Ultrasonic Cleaner1 x English User Manual1 x Power CableNote:1. 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.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)7. When changing liquid or draining, it should be carried out in the tank at normal temperature, and be sure to turn off the power and unplug the power cord! (After cleaning, do not accumulate in the cleaning tank!)8. Keep the appearance of the machine clean when cleaning; clean the machine after stopping, keep the whole machine clean and dry9. Each working time should not be too long. It should be stopped for 15 minutes after 15 minutes of power-on to better protect the machine and reduce the failure rate.
