Many Cool Things You Can Do with XUX hot glue gun!\r\n\r\nEasy to Operate:\r\n1. Insert one glue stick into the gun tail.\r\n2. Plug in and switch on, the LED indicator will light up.\r\n3. Preheat for 3-5 minutes.\r\n4.

Do not pull out the glue stick from the back of the gun. If there is half-used glue stick in the gun, just feed in another new one behind it and it’ll continue to feed through the new glue stick smoothly.\r\n2. Please turn off the red switch and use the holder to keep the nozzle downward after each use. It doesn\'t leak but because of gravity, when you just have used it at the moment and put it back on the base immediately, the tip is still hot. It is normal to have a little glue drop. Don\'t worry.\r\n3. If you don‘t use the glue gun frequently for a short time or plan to stop the work. Please turn off the switch of the gun in advance within 10 mins so that it wont continously melting the glue stick. It is very convinient and safe. This will make the life of the glue gun longer.\r\n4. Dont worry. Our original tip inner diameter is 2mm, the amount of glue is slightly larger, mainly for industrial use. In addition, we additionally equipped a extra new tip inner diameter is 1mm, which is small in size and suitable for home use, and is used for hand crafts. Please feel free to buy and use.\r\n5. If the glue gun does not work continuously for 15 minutes, please cut off the power supply.\r\n6. Do not disassemble or modify the glue gun.
