Desiccant status
Please note that this IS NOT GREASE, instead, it is a fully moisturized desiccant. DO NOT try to apply it on any bearing or rail as it will damage them.
When it reaches the final stage (ineffective) please dispose of the package.
Note: Please check the status of the desiccant every two weeks, if the desiccant has failed, please replace it in time. If the desiccant is not replaced for a long time, it will lose its ability to absorb water, thus losing its ability to protect the dried filament. In addition, when it is not replaced for more than 3 months, the desiccant may also leak water, short-circuit, or damage the circuit or electronic components inside the AMS.
Here is a picture of the actual packaging of the desiccant:
