Instructions for use and precautions:

1. Insert the 7 MM or 11 MM diameter glue rod from the tail of the glue gun until it is confirmed to be inserted into the gun barrel. Attach the bracket, place the gun on a tabletop, and connect to power. Preheat for 3–5 minutes before using the extrusion glue. Remember not to run it without use, or if there is no glue application for 15 minutes, please disconnect the power first.

2. During use, if a leftover strip of adhesive is present, do not remove it. It can be kept and used directly after being plugged in and preheated for 3–5 minutes the next time.

3. When the glue gun is in use, do not lift it high to prevent backflow. This tool must be placed on a stand to ensure it remains tilted. A slight smoking phenomenon inside the gun during the first use is normal; the smoke will disappear after some time of use.
