How to Clean the Grinder

1. Remove the receiver, attach the handle, and hold the grinder as demonstrated.
2. Rotate the spin dial counterclockwise to disassemble the grinder.
3. Take out the components in order: spin dial, numerical dial, inner burr, spring, and bearing cover. (Note: No need to remove the central shaft.)
4. Use the brush to clean the grinder.
5. Place the components back in order: bearing cover and spring. There are two shapes of the bearing cover: flat design and curved design. Ensure the curved design faces upward.
6. Attach the inner burr and the numerical dial to the rectangle shape of the central shaft to proceed with assembly.
7. Install the spin dial and rotate clockwise to complete the assembly.

Precautions

• The entire grinder should not be washed with water. Use the brush for cleaning.
• Do not rotate the handle when the grind setting is at 0 or below 16 clicks, as this could damage the burr set.
• For precision reasons, do not dismantle the exterior burr. Avoid forcefully disassembling the grinder with tools.
• Only grind coffee beans. Do not grind unroasted coffee beans.
• Avoid spraying water directly onto any part of the grinder. RDT (Ross Droplet Technique) can be performed by spraying water on another object.
• Avoid second grinding, as the coffee fine powder may block the parts.
• Please store in a dry environment.

How to Assemble the PC Lid and Handle

1. Take out the black O-ring from the groove on the PC lid.
2. Insert the provided white O-ring.
3. Ensure that the white O-ring is correctly installed into the groove on the handle for proper fixation.

How to Use it by Electric

You need to prepare:

• Electric screwdriver with 15-25Nm torque.
• 6.35mm (1/4 inch) Hex Shank bit holder.

1. Take out the handle and install the black O-ring to the PC lid.
2. Ensure that the bit holder is fully inserted into the center shaft. Grasp the grinder firmly and gradually apply power.

Caution: Slow down the grinding speed to prevent damage to the central shaft.
