To set the burrs so they are in the correct position, loosen the lock ring and turn the cutter body to the finest position to where the burrs touch. It should be about 0.05mm. Take note of the exact position, then loosen the cutter retaining screw. Secure the lock ring so the grind adjustment is set at the position where the burrs touch. The lock ring needs to be just as you would set it for operation, but don't do it up too tight. Turn the grinder upside down so the bottom is facing up. Gently turn the handle backwards a few times. The burrs will rub lightly. This will allow the male burr to find the most concentric position. There is a small amount of clearance between the burr and shaft so it can move slightly to find the best position. It will normally find this position on its own during operation. Now tighten the screw very lightly, and turn the handle again. If it feels tight, loosen the screw a bit. Wind it backwards a few times, then tighten the screw. Now place your hand on the main body and fingers on the lock ring. Turn the lock ring to loosen. Once loose, back the cutter body off the fine setting so the burrs are clear. Set at 0.4mm and see if it runs free. If it rubs, loosen the cutter body and reset until it spins free. The very small amount of clearance between the threads can make a difference. If it won't run free, repeat the full process. It can take a few times to find the optimum position. Note it will normally find this position on its own during operation, and since the variance is only a few hundredths of a millimeter, the shaft will flex enough under load to grind evenly so the grind size won't be effected, but it should find the best position over time without doing anything. After some use, you should be able to get it spinning freely as low as 0.2mm or less.
Check the lock ring is on the correct orientation. One side has a recess so it clears the thread when wound on fully. The recess side goes on first. Only one side of the ring is guaranteed to be square to the thread. The other side can be off slightly because it is not machined at the same time. If on backwards, there could be enough error to effect alignment. Also note that the lock ring needs to be secured. If it's loose, the clearance in the threads can offset the alignment causing burr rub. It's not used loose, so ensure it is secured before testing.
