A: Ultrasonic cleaning is based on the cavitation effect caused by high frequency ultrasonic wave vibration signal in the fluid. 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. The bubbles are small through 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 head, nib, coins, badges, pacifiers, etc. Q: Which washer liquid can be properly added for better cleaning during the cleaning process? A: You can add cleaning liquid or detergent, such as: detergent, soapy water, disinfectant, etc. However, do not add acid or alkaline solution to the machine to prevent ABS corrosion damage.. Package List: 1 x Ultrasonic Cleaner1 x User Manual 1 x Power Cable Note: 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 5 minutes after 15 minutes of power-on to better protect the machine and reduce the failure rate.
