Operating Instructions
Powering On and Preheating
- Slide the ON/OFF switch, located on the side of the glue gun, to the "ON" position.
- The LED indicator light will illuminate, and the glue gun will begin to heat up.
- Allow the glue gun to preheat for approximately 3-5 minutes until it reaches its operating temperature. The nozzle will become hot.
Applying Glue
- Once heated, gently squeeze the trigger to dispense molten glue from the precision nozzle.
- The built-in LED light will illuminate your work area, aiding in precise glue placement, especially in low-light conditions.
- Apply glue to one surface and quickly press the surfaces together. Hot glue sets rapidly, typically within 15-30 seconds, for optimal bonding.

Maintenance
Cleaning
