Important Safety Instructions
Please read all instructions carefully before using the blender. Failure to follow these instructions may result in injury or damage to the appliance.
- Always ensure the lid is securely attached before operating the blender. The magnetic safety design prevents operation without the lid.

- Do not immerse the motor base in water or other liquids.
- Unplug the blender from the power source before cleaning or when not in use.
- This appliance is not intended for use by children. Close supervision is necessary when any appliance is used near children.
- Do not operate any appliance with a damaged cord or plug, or after the appliance malfunctions or has been dropped or damaged in any manner.
- Use only attachments recommended or sold by the manufacturer.
