Important notes before using: 1. Prior to usage, please ensure that the gear at the bottom is properly secured. If it is loose, tighten it. 2. Verify that the rubber gasket is securely placed inside the bottom blade. This gasket prevents leaks. 3. Avoid overfilling the container! To prevent spills, do not exceed the Max fill line when adding ingredients. 4. Attach the replacement blade to the cup and firmly screw it on until a tight seal is achieved. 5. Ensure that it is correctly positioned and securely locked in place.
