TIPS FOR USAGE
1. It is recommended that the blade unit should be replaced for your blender every 6 months or as needed for optimal performance.
2. Please check whether the gear of the bottom tighten before use.
3. Check the rubber seal ring gasket and make sure it is snugly inserted into the bottom blade. (Rubber gasket is used to avoiding leakage)
4. To avoid spilling, do not add ingredients past the "Max" fill line.
5. Place the replacement blade onto the cup and screw it tightly until you have a good seal.
6. Pay attention to safety when using sharp blender blade.
7. Do not run your blender over 4 minutes at a time to prevent overheating of the blender.
