1. Set Finest Grind Setting and Prepare Tools
Set the grind setting to '1' (finest) and prepare a 10mm socket.
Exercise caution as grinder burrs are extremely sharp.
2. Loosen Central Nut
Using the 10mm socket, turn clockwise to loosen the nut only.
Only loosen the nut - do not remove it completely.
3. Remove Lower Components Sequentially
Remove the nut, spring, flat washer, and carefully remove the lower burr.
Note the alignment of the drive pin and cavity.
4. Remove Grind Fan and Washer
Use long-nose pliers to remove the grind fan and washer.
Remember the removal order for easier reassembly.
5. Clear Chute Blockage
Use a brush or pipe cleaner to clear any blockages in the ground coffee discharge chute.
Compressed air may be used for stubborn blockages.
6. Clean All Components with Brush
Thoroughly clean all removed parts with a brush.
Do not use water and ensure all parts are completely dry before reassembly.
7. Reassemble in Reverse Order
Reassemble in order: washer → grind fan → lower burr → washers → nut.
Tighten the nut counter-clockwise but avoid over-tightening.
8. Reset Grind Setting and Test
Set grind setting to '16', reattach the hopper, and perform test grinds.
Initial grinds may be inconsistent, so perform multiple tests.
