User Instruction

1. Turn the adjustment dial ring counter-clockwise to make the grinds finer and vice versa. Zero the grinder by turning the adjustment dial ring counterclockwise all the way to the starting point where the resistance starts and the central shaft can’t spin freely.
   Warning: Do not over-tighten the adjustment dial ring.

2. There are 5 and a half rotations in total, 60 clicks in a single rotation; each click moves the burr by 0.0125mm/12.5 microns.

3. Refer to the grind setting tutorial post for different brewing methods.

4. Put coffee beans in the hopper and turn the handle clockwise to start grinding.

5. Follow the guide to calibrate the grinder after reassembling the grinder.

Note:
The grinders were calibrated when manufactured. To prevent the burrs from being stuck, please do not over-tighten the adjustment dial. Do not turn the handle should the burrs get stuck; just loosen the dial and press the central shaft down. Website: www.1zpresso.coffee YouTube/Facebook/Instagram: 1zpresso
