[Internal / Top Numerical Adjustment]

  • Turn the adjustment dial clockwise till the lowest grind setting.
  • Turn the adjustment dial anti-clockwise to the preferred grind setting.
    More rotations/rounds mean a coarser grind size.

[External Numerical Adjustment Ring]

  • Turn the adjustment dial anti-clockwise till the lowest grind setting.
  • Turn the adjustment dial clockwise to the preferred grind setting.
    The RedDot pointer indicates the grind setting. Turn the adjustment dial to adjust the grind setting, it’s just like the electric grinder. The higher the number, the coarser the grind.

All the 1Zpresso grinders are able to be dismantled without any tools and allow thorough cleanliness and maintenance lacking the need to re-calibrate the burr.

  • The grinder can be clean with a dry brush and an air blower. 
  • Disassemble the grinder and clean it thoroughly once a month. It would maintain the grinding results and life-time of the grinder.
  • Do not clean the grinder with water.

Simply grind rolled oats or instant oats, wipe with a damp (not wet) towel, and dry immediately. Excessive moisture will damage the grinder.


The 6.35mm electronic screwdriver/drill is applicable to all the 1Zpresso grinders and it doesn’t need to be a powerful one.
We suggest using a drill for one or two cups within a short period of time, or it could get hot and affect the taste.

Spray some water on the beans to eliminate static.
Notes: Excessive moisture will damage the grinder, so be sure to store the grinder at a dry location.

The burr in the grinders were calibrated by our team to ensure maximum stability over time, and it is expected to grind up to 100~200 kg beans. We’re developing a burr replacement service, so stay tuned.

Minor imperfections on the surface of the metal are to be expected during the aluminum anodizing process. Our QC team is limited to substantial cosmetic defects.

The soft brush is made from nylon wool fiber and the hard brush is made from horsehair fiber.


All 1Zpresso grinders are under an one-year limited warranty for defects in materials and workmanship.

We offer instruction videos on our 1Zpresso Youtube Channel, or you can Contact Us for specific technical problems and we will reply you as soon as possible.

Our team calibrates all the 1Zpresso grinders at the factory to ensure precision, but it is impossible to align the burrs perfectly without any misalignment technically. Therefore, please refer to our grind setting reference charts and do not turn the handle within the first few clicks from the zero point to avoid the burrs from being damaged.

Grinders might get stuck when the adjustment dial is over-tightened and this can simply be resolved by adjusting the dial to coarser settings and pressing the shaft from the top. If this doesn’t solve the issue, please ensure the entire adjustment dial ring and the outer ring unit are not loose (both parts have left-handed threads and need to be tightened counter-clockwise) or contact customer service via email directly.

The only difference between an “S” and a “non-S” model is the handle. The “S” models have a foldable handle, like JX-Pro S and J-Max S, while the “non-S” models, such as JX-Pro and J-Max, come with handles that don’t fold.
