Use suggestions:
Before use, make sure to close the bottom blade on the cup tightly enough.
Please check if the bottom gear is loose or tightened before use. If it is loose, tighten it.
Make sure that the rubber gasket is close to the bottom blade. (Rubber gasket is used to avoid leakage).
Don't overfill it! To avoid spillage, do not add ingredients that exceed the "maximum" fill line.
Do not run the mixer for more than 4 minutes at a time to prevent the mixer from overheating.
Please recommend that you replace the ninja blender blades every 6 months or as needed for best performance.
