User Instructions

J-series grinder
Adjust the dial clockwise for finer grinds. Adjust the dial counter-clockwise for coarser grinds.

Adjusting the grind setting

Turn the adjustment dial clockwise to make the grinds finer and vice versa.

  1. Attach the crank handle and stop it from rotating.
  2. Turn the adjustment dial clockwise to the tightest. The number (#) marked at the dot is the starting point/zero point.
    NOTE: the number (#) might not be 0.
  3. Turn the adjustment dial counter-clockwise from the zero point to the grind setting you like.
  4. There are 10 numbers/30 clicks in a single rotation; every rotation moves the burr by 0.75mm.
  5. Grinds remaining in the grinder might make the zero points different.
  6. Kindly refer to the grind setting tutorial post for several brewing methods.

Coffee Grinding

  1. Put the coffee bean into the hopper after removing the handle. The maximum capacity is around 20g.
