Specification: Inner Groove Size: Approx. 300 x 240 x 150mm / 11.8 x 9.4 x 5.9in Dimensions: Approx. 330 x 270 x 330mm / 13 x 10.6 x 13in Ultrasonic Power: 240W Heating Power: 300W Package List: 1 x Ultrasonic Cleaner 1 x English Manual 1 x Power Cord Note: 1. When the ultrasonic wave is in normal operation, the uniform sound of the ultrasonic wave 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. Eliminating the oscillations helps to cleaning the objects 2. Under the premise of ensuring that the cleaning objects are cleaning, work as intermittently as possible and do not warm, because the warming and long-time ultrasonic work will increase the temperature inside the chassis, and it is easy to accelerate the aging of the electronic devices 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 components 6. If any foreign object falls into the bottom of the tank, it should be taken out immediately (not directly taken 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 cleaning when cleaning; cleaning the machine after stopping, keep the whole machine cleaning and dry 9. Each working time should not be too long. It should be stopped for five minutes after 15 minutes of power-on to better protect the machine and reduce the failure rate.
