The printer has 110VAC / 230VAC and other high voltage power interfaces. Do not use any other power cord other than the one provided. Use approved power cords and sockets to ensure power cords are not damaged. 4. Do not place the printer in a large vibration or other unstable environment, the machine shake will affect the printer print quality. It is recommended to place it in a well-ventilated and low-dust environment to avoid over- heating of the machine. 5. Risk of scalding: Do not touch the nozzle and hot bed when the printer is working to prevent high tempera- ture scalding. After printing, timely using the residual temperature of the nozzle to clean the consumables up on the nozzle with the help of tools, and do not touch the nozzle with your hands directly during cleaning to prevent scalding. ћӝŚȃljȶɽȃljȴƃƺȃȈȶljȈɰɨʍȶȶȈȶǼӗɥȢljƃɰljɰɽƃʰƃʥƃʰǹɨɁȴɽȃljɥƃɨɽɰȈȶɁɥljɨƃɽȈɁȶӗƃȶǁƃʤɁȈǁɥɁȟȈȶǼʰɁʍɨˎȶǼljɨɰɁɨ other objects into the inside of the running printer to prevent injury. 7.
