Please read the manual carefully and pay attention to the safety precautions inside. Please keep the tool away from children. Please never point it at anyone. When purchasing an electric glue gun, please choose the one that is suitable for your glue application. Slow down the speed of the glue nozzle when it is small, and speed up the speed of the glue nozzle when it is large. When the temperature is below 68°F, please be sure to heat the adhesive in hot water at 140-158°F for ten minutes. The electric glue gun has a high thrust. To prevent tube explosion and glue leakage, we have set up a protection program. When the thrust is too high, it will automatically retreat. Please do not forcefully apply glue. If there is glue on the screw or rack raceway, it should be promptly wiped to prevent the glue from entering the machine body (a small amount of alcohol can be dipped in a cloth to apply). After a period of use, a little butter can be applied to the screw roller track for maintenance (do not add liquid lubricants such as engine oil). Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before you order.
