The grinder is ready to use out of the box. Turn the adjustment dial ring counter-clockwise all the way to the starting point where the resistance starts and the crank handle can’t spin freely. The #0 will be aligned with the scale mark and the bottom edge of the adjustment dial ring will touch the first tier of the scale mark.
The pyramid-shapedscale mark consists of multiple squares that indicate how many rotations you are at, and it gets smaller while you set coarser settings.
There are four and a half rotations in total. 90 clicks in a single rotation and each click moves the burr by 0.0088mm/8.8 microns.
Turn the adjustment dial ring clockwise to find the grind setting.
Attach the rubber band to the grinder for a better grip.
Put coffee beans in the hopper and turn the handle clockwise to start grinding.
Follow the guide to calibrate the grinder after disassembling and reassembling the grinder.
Diassembly
Warning: Do not loosen the burr ring unit before step 3.
Turn the adjustment dial ring clockwise by around two rotations and remove the knurled thumb nut counter-clockwise while pressing the burr.
Remove the upper bearing cap and upper bearing.
Remove the burr and central shaft, spring and lower bearing cap.
Turn the burr ring unit forward (reverse threads). Disassembling the adjustment dial ring is not suggested.
Do not clean the grinder with water. Cleaning with a brush and blower is recommended.
Turn the burr ring unit backward (reverse threads) to the tightest position.
Align the #0 with the scale mark and the bottom edge of the adjustment dial ring touches the first tier of the scale mark.
Put the components back in the right sequence: lower bearing cap (the raised edge side facing upward), spring, shaft and burr.
Put the upper bearing back from the top.
While pressing the burr from the bottom, put the upper bearing cap back. The side with concave dots faces upward, and the U-shaped hole fits the shaft properly.
Tighten the knurled thumb nut to calibrate the grinder while pressing the burr from the bottom.
Note: There are four and a half rotations in total counted from the starting point. The starting point might be different within ±10 clicks due to the strength you tighten the nut and dial.
