Greetings, fellow coffer-lovers.

How often that you clean your 1Zpresso manual coffee grinder? 
Proper maintenance could prolong the life of your grinder for a long period of time.
We advise customers to dismantle the grinder once a month to perform cleaning and maintenance.
The grinder could dismantle without any helps from the tool.

Here is a reassemble tutorial for the top adjustment mechanism of K-Pro & K-Plus grinder.
You also can find the cleaning and maintenance tutorial of the internal adjustment and top adjustment from our blog.

Step 7:

Place the pieces in order to ensure the grinder works perfectly. The central shaft and the burr set fixed together, you need to put it back into the grinder. Before that, you have to place the spring then the bearing cap on the burr set.

Note: the spring is the conical shape in which you need to place the larger surface upward as the opposite of the smaller surface and the protruding side of the bearing cap consider facing upward.

Step 8:

Insert the upper bearing into the adjustment dial ring. Now it is a tricky part, you would notice there is a horseshoe shape appearing from the upper bearing cap. The flat side from the upper bearing cap needs to match the flat side of the central shaft as well.
