2. Safety Instructions
To prevent injury or damage, always observe the following safety precautions:
- The glue gun operates at high temperatures. The nozzle and melted glue can cause severe burns. Do not touch the nozzle or melted glue directly.
- Ensure the glue gun is placed on a stable, heat-resistant surface when not in use. The built-in stand provides stability.

- Keep the device out of reach of children. Close supervision is required if children are present during operation.
- Do not tilt the nozzle upwards when the glue gun is hot, as this may cause melted glue to flow back into the mechanism.
- Never pull out a partially used glue stick from the back of the gun while it is hot. Allow it to cool or push it through with a new stick.
- The glue gun features a flame-retardant housing and a heat-resistant silicone nozzle cover for enhanced safety.
