5. Maintenance
- Nozzle Cleaning: The glue gun features a replaceable heat-resistant copper nozzle. If back-flow occurs or the nozzle becomes clogged, allow the gun to cool completely. Use a needle or a small tool to carefully clean any hardened glue residue from the nozzle and the glue stick entry point.
- Glue Stick Management: To prevent blockages and ensure smooth operation, keep glue sticks clean and free of debris. When a glue stick becomes shorter, insert a new one to push the remaining portion for further use.
- Storage: Always remove the battery from the glue gun before storing. Store the glue gun in a dry, safe place away from direct sunlight and extreme temperatures.
