Dear customer, each of our juicers is tested before shipment. If the juicer does not work, please check whether there are the following problems: 1. Whether it is fully charged (please charge for 5 hours before first use) 2. Whether the container is tightened (after tightening, the transparent part of the container body is roughly aligned with the display panel, otherwise it will default to empty container state and cannot be started) 3. Observe whether the blade is stuck due to the large pulp. Solution: ① Turn the machine upside down, tilt the pulp onto the container lid, wait for the blade to rotate, and then shake the container quickly at 45 or 60 degrees.② Cut the fruit meat into 1*1cm size 4. It cannot be used when charging
