This tutorial is for the JX-Pro S JE-Plus grinder

Greetings, fellow coffer-lovers.
This tutorial allows you to learn how to clean a 1Zpresso top adjustment grinder

How often do you clean your 1Zpresso manual coffee grinder? Proper maintenance could prolong the lifetime of your grinder. We advise customers to dismantle the grinder once a month for cleaning and maintenance. The grinder could be dismantled without any tool.

Here is a reassembly tutorial for the top adjustment mechanism of the JX-Pro S & the JE-Plus grinder. You also can find a cleaning and maintenance tutorial of the internal adjustment and external adjustment from our blog.

Step 7

Put the parts back in order to ensure the grinder works properly. Before attaching the burr set to the body, you have to put the spring then the bearing cap back on the burr set.

Note: The wide side of the conical-shaped spring and the side of the bearing cap with a raised edge should face upward.

Step 8

There is a dot at the back of the sliding column. Place the sliding column (which connects the dot at the sliding column with the dot at the adjustment dial) inside the hopper.

Put the sliding column into the upper ring cap, then the upper bearing.

Now it is a tricky part, you might notice that the upper bearing cap is horseshoe shape. The flat side of the upper bearing cap needs to match the flat side of the central shaft.

Step 9

Tighten the knurled thumb nut by turning it clockwise while pressing the burr set.

Free your hand from pressing the burr set, tighten the adjustment dial by turning clockwise till you feel resistance (do not overtighten or it hurts the burr set).

Where the crank handle is unable to move dramatically is the zero point of the grinder.
