Followed by step 5.1 – Apply a 6mm hex key/Allen key to install the pc lid by turning clockwise till it tightens.
Step 7
Place the pieces in order to ensure the grinder works perfectly. The central shaft and the burr set fixed together, you need to put it back into the grinder. Before that, you have to place the spring then the bearing cap on the burr set.
Note: the spring is the conical shape in which you need to place the larger surface upward as the opposite of the smaller surface and the protruding side of the bearing cap consider facing upward.
Step 8
Insert the upper bearing into the adjustment dial ring. Now it is a tricky part, you would notice there is a horseshoe shape appearing from the upper bearing cap. The flat side from the upper bearing cap needs to match the flat side of the central shaft as well.
Step 9
Pressing the burr set and tighten the knurled thumb nut by turning clockwise till you feel a resistance (do not overtighten or it hurt the burr set).
