1. Please check whether the gear of the bottom loosens or tighten before use. If it's loosened, please tighten it
2. Please check the rubber gasket and be sure it is put snugly into the bottom blade. (The rubber gasket is used to avoiding a leak)
3. Do not overfill! To avoid spilling, do not add ingredients past the Max fill line
4. Place the replacement blade onto the cup and screw it tightly until you have a good seal
5. Please make sure it in the right place and locked tightly
