Ensure that the battery is properly placed in the charger. If there's no light indication, check if the outlet is functioning correctly. If the charger still doesn't show any light, it means that the charger needs to be replaced.
After the battery is fully charged, attach it to the tool and press the power button to start.
Please be aware that you should not vacuum hot items such as carbon and cigarette butts, liquids, sharp objects, and ultra-fine substances. These could potentially damage the machine or cause an accidental fire, leading to personal injury. For more information on Product Safety, refer to your owner’s manual.
