Common questions about manuals, registration, and support for this brand.
Ensure the gun is fully heated by waiting the recommended 3 to 6 minutes, check that the glue stick is correctly inserted, and pull the trigger smoothly. Also, ensure the nozzle is not blocked by hardened glue.
Full-size industrial and professional AdTech glue guns typically use 1/2-inch (12mm) or 0.44-inch high-temp glue sticks. Mini and low-temperature models require 0.28-inch mini glue sticks.
Stringing or dripping occurs if the tool is not completely brought up to temperature before use, if the wrong type of glue stick is inserted, or if there is excessive continuous heat during idle times. For dripless models, verify the needle-valve nozzle is clear of obstructions.
Always unplug the glue gun before cleaning. Let it cool slightly, then wipe the nozzle carefully with a dry cloth to remove residue. Never immerse the tool in water and do not pull unused glue sticks out from the back of the gun.
