NOTES\nPLEASE READ THIS MANUAL BEFORE USING THE DEVICE, PAYING EXTRA\nATTENTION TO THESE SAFETY WARNINGS AND GUIDELINES. PLEASE KEEP THIS\nMANUAL IN A SAFE PLACE FOR FUTURE REFERENCE.\n\n\n1.1. Safety Warnings\n Do not touch the nozzle or stepper motors, when the 3D printer is printing or just finished the\n printing job, the nozzle temperature is up to 230°C.\n\n Do not expose this device to water or moisture of any kind. Do not place drinks or other\n containers with moisture on or near the device. If moisture does get in or on the device,\n immediately unplug it from the power outlet and allow it to fully dry before reapplying power.\n\n Do not touch the device, the power cord, or any other connected cables with wet hands.\n\n Prior to operation, check the unit and power cord for physical damage. Do not use if physical\n damage has occurred.\n Before plugging the unit into a power outlet, ensure that the outlet provides the same type and\n level of power required by the device.\n Unplug this device from the power source when not in use.\n\n Take care to prevent damage to the power cord. Do not allow it to become crimped, pinched,\n walked on, or become tangled with other cords. Ensure that the power cord does not present a\n tripping hazard.\n\n Never unplug the unit by pulling on the power cord. Always grasp the connector head or\n adapter body.\n Ensure that the 3D printer is turned off and unplugged from its power source before making\n repairs or performing service.\n\n\n\n\n1.2. Filament\nTo use this 3D printer, please use the filament provided by our company. Filaments sold in the retail\nmarket have different specifications and uneven quality, which can easily clog and damage the nozzle\nand motor. If the 3D printer fails due to the use of third-party consumables, the warranty will not be\ngranted.\n\nIf the filaments are not used for a long time after unpacking, please seal them and preserve them.\nPLA will absorb moisture when exposed to air for a long time, affecting the quality of printed\nproducts.\n\n\n\n 1", "1.3. Environmental Requirements\nThis 3D printer is intended for indoor use only. The ideal ambient temperature is 15°C - 25°C. When\nthe ambient temperature is lower than 10°C, the printing model is hard to adhere to the platform.\nWhen the ambient temperature is lower than 0°C, the device will not startup. When the ambient\ntemperature is higher than 30°C, the print quality will decline significantly and the nozzle may be\nclogged.\n\n\n\n\n 2", "2. INTRODUCTION\n2.1.
