Introduction
Thank you for choosing the AdTech Pro 75 Full Size Hot Glue Gun. This manual provides essential information for the safe and effective use of your new tool. Please read all instructions carefully before operation and retain this manual for future reference. The AdTech Pro 75 is designed for various crafting and bonding applications, featuring a powerful 75-watt heater and interchangeable nozzles for precision and versatility.
Setup Instructions
- Unpacking: Carefully remove all components from the packaging. Ensure you have the glue gun, three interchangeable nozzles, and any included glue sticks.
- Nozzle Attachment: The AdTech Pro 75 comes with three interchangeable nozzles: a general-purpose nozzle, a fine-detail nozzle, and a gap-filling nozzle. To attach a nozzle, ensure the glue gun is unplugged and cool. Screw the desired nozzle clockwise onto the tip of the glue gun until it is finger-tight. Do not overtighten.
- Glue Stick Insertion: Insert a full-size (0.44 inch / 11.2 mm diameter) hot glue stick into the circular opening at the back of the glue gun. Push it gently until it stops.
- Positioning the Stand: The glue gun features a flexible dual-positioning design. You can use the integrated folding stand for upright stability or lay the gun flat on its side to prevent dripping when not in active use.
- Power Connection: Plug the power cord into a standard 120V AC electrical outlet.
- Initial Heating: Allow the glue gun to heat up for approximately 3-5 minutes. The 75-watt heater ensures swift heating and a steady glue flow.

Operating Instructions
- Power On/Off: The glue gun features an integrated On/Off switch for convenient control. Flip the switch to the 'On' position to begin heating.
- Applying Glue: Once the glue gun is heated, gently squeeze the ergonomic trigger to dispense hot glue. The three-finger ergonomic trigger enhances glue flow management, allowing for precise application. Apply glue to one surface and press the two surfaces together within 15-30 seconds for optimal bonding.
- Nozzle Selection: Choose the appropriate nozzle for your task. The fine-detail nozzle is ideal for intricate work, the general-purpose nozzle for standard applications, and the gap-filling nozzle for larger areas or filling voids.
- Continuous Use: As the glue stick shortens, insert a new glue stick into the back of the gun to push the old one through.
- Safety Precautions: The nozzle and dispensed glue will be extremely hot. Avoid direct contact with skin. Always place the glue gun on its stand or lay it flat on a heat-resistant surface when not in use. Do not leave the glue gun unattended while plugged in.

Maintenance
- Cleaning the Nozzle: After use, allow the glue gun to cool completely. Any excess glue on the nozzle can be carefully removed once hardened. Do not attempt to clean the nozzle while the gun is hot.
- Storage: Store the glue gun in a clean, dry place away from direct sunlight and extreme temperatures. Ensure no glue sticks are left partially melted in the chamber during storage.
- General Care: Periodically inspect the power cord for any signs of damage. If the cord is damaged, discontinue use and contact customer support.
