1. Dial Pointer

2. Adjustment Dial Ring

Turn the adjustment dial ring clockwise to coarser

grind settings as the burrs open up.

Loosen the knurled thumb nut by turning it

counterclockwise while pushing the burr. Then, remove

the upper bearing cap and upper bearing from the top.

Remove the shaft, inner burr, lower bearing cover, and

spring.

Detach the burr ring unit and the entire adjustment

dial unit by turning it clockwise.

Clean all parts using a brush and an air blower.

Turn the entire adjustment dial unit counterclockwise

to its tightest position.

Rotate the adjustment dial ring clockwise to set a coarser

grind setting.

Turn the burr ring unit counterclockwise to its tightest

position.

Insert the spring followed by the bearing cap (raised

edge facing upward) onto the shaft, then place the shaft 

back into the grinder.

While pressing the burr, reinstall the upper bearing and

upper bearing cap (dotted side facing upward). Ensure

the bearing cap is placed correctly.

Turn the knurled thumb nut clockwise while pushing the

burr, stopping when you feel resistance.

Set the adjustment dial ring to zero and check if the

indicator aligns with #0.

If misaligned, refer to the calibration guide below.

1. Find the Zero Point: Turn the adjustment dial ring

counterclockwise until you feel resistance (the handle

starts to spin with resistance), not the tightest position.

This is the zero point.

2. Verify Alignment: The grinder is calibrated if the dial

pointer aligns with #0 when the adjustment dial ring is at

its zero point.

3. Adjust if Needed: If the dial pointer does not align with

#0, follow the steps below to calibrate.

Read the following steps for calibration if you don’t get #0

for the zero setting. 

If the Dial Pointer is to the Right of #0:

1. Turn the adjustment dial ring clockwise to a coarser

setting, increasing the gap inside.

2. Loosen the knurled thumb nut slightly by turning it

counterclockwise while pressing the burr from the bottom.

3. Turn the adjustment dial ring counterclockwise back

to the zero setting and check the dial pointer.

Repeat as needed until properly calibrated.

If the Dial Pointer is to the Left of #0:

1. Turn the adjustment dial ring clockwise to a coarser

setting, increasing the gap inside.

2. Tighten the knurled thumb nut slightly by turning

it clockwise while pressing the burr from the bottom.

3. Turn the adjustment dial ring counterclockwise back

to the zero setting and check the dial pointer.

Repeat as needed until properly calibrated.

1. Before inserting the shaft with the inner

burr, turn the dial counterclockwise all the

way and align the dial pointer with zero.

2. Place the shaft with the inner burr, bearing,

bearing cap, and knurled thumb nut into

the grinder.

3. Pressing the burr from the bottom until the

burrs close up completely while

tightening the knurled thumb nut.

4. Your grinder should now be calibrated. If

the dial pointer still passes zero, loosen the 

adjustment dial clockwise slightly and

repeat Step 3 until it aligns with zero.

Hold the crank part near the wooden knob and

push it in.

Hold the crank part near the wooden knob

and push it in.

Turn the handle counter-clockwise

all the way to unfold.
