01 | Am I supposed to open the grinder burr set?
You can remove both the burr and all other parts like washer, crank and spring. But please do not detach the screws of the burr set since they have been adjusted in a optimal way for the grinding gear.
02 | Can I release the screws at the bottom of the grinder?
Do not loosen the screws at the bottom of your Comandante grinder. These three screws have been fixed precisely by our manufacturers and are not meant to be detached.

Take a look at the mechanical drawing below. The O-Ring belongs between the washer and the spring.

To keep your grinder clean you can wash the burr with lukewarm water and/or use a small piece of absorbent cotton or a cotton bud.
