                          \n
                        1. \n

                        2. \n

                          Adjust the <\/span>temperature controller gauge of the glue trough<\/span><\/strong> to the temperature of about <\/span>160\u2103<\/span><\/strong>.<\/span><\/p>\n<\/li>\n

                        3. \n

                          Then adjust the <\/span>temperature controller gauge of the glue gun<\/span><\/strong> to the temperature of about <\/span>180\u2013190\u2103<\/span><\/strong>.<\/span><\/p>\n<\/li>\n

                        4. \n

                          After about <\/span>20 minutes<\/span><\/strong> of heating, after the glue trough gets the right temperature, power can be connected to the <\/span>motor switch<\/span><\/strong>.<\/span><\/p>\n<\/li>\n

                        5. \n

                        6. \n

                          If you turn on the motor switch and the motor does not work, it means that <\/span>glue trough temperature is not enough<\/span><\/strong> and should be heated more.<\/span><\/p>\n<\/li>\n

                        7. \n

                          Open the <\/span>glue trough gate<\/span><\/strong> and put a piece of glue in for melt.<\/span><\/p>\n<\/li>\n

                        8. \n

                          After melt, it is used for spray. When out of glue, we can put another glue piece to melt again.<\/span><\/p>\n<\/li>\n

                        9. \n

                          Do not keep too much glue in the glue trough and heating<\/span><\/strong>. It will deduct the melt glue’s quality.<\/span><\/p>\n<\/li>\n<\/ol>\n<\/div>
