Important Safety Instructions
To ensure safe operation and prevent damage, please observe the following safety guidelines:
- Always ensure the bottle is correctly aligned with the base (red arrow on bottle aligned with the switch) before operating. The blender will not start if not properly aligned, and indicator lights will flash.
- Do not immerse the blender base in water for extended periods, despite its IP67 waterproof rating. The charging port is waterproof and can be rinsed, but prolonged submersion is not recommended.
- Avoid blending hot liquids or ingredients. Pressure can build up, leading to an explosive discharge when opening the lid or leakage from the base.
- Keep hands and utensils out of the blender jar while operating to prevent injury.
- The blender features overheat protection. If the motor overheats, it will automatically shut off. Allow it to cool down before resuming use.
