I keep on forgetting which direction to adjust the 1zpresso, so here’s a reference page.

Assuming you are looking directly at the grind adjuster:

JX

Finer

Turn the hand (where the reference marker is) clockwise (the numbers will get larger).

Coarser

Turn the hand (where the reference marker is) anti-clockwise (the numbers will get smaller).

JX Pro

Finer

Turn the dial (where the numbers are) clockwise (the numbers will get smaller).

Coarser

Turn the dial (where the numbers are) anti-clockwise (the numbers will get larger).
