Determine the direction of adjustment you need (finer or thicker). Make sure there are enough coffee beans in the warehouse, and the valve between the warehouse and the sharpening knife is opened so that the coffee beans can fall smoothly into the grinding area.

Turn on the grinder for 10 seconds and discard the coffee powder (these are coffee powders that have not been adjusted).

Use the coffee powder to make a cup of coffee to ensure the accuracy of the steps of serving, flattening and pressing powder. The traditional method of making espresso (Ristretto) uses a water / flour ratio of 1:1 (i.e. 18 grams of coffee powder is used to make 18 grams of coffee) or 1:2 (i.e. 18 grams of coffee powder is used to make 36 grams of coffee), while a regular espresso uses a water / powder ratio of 1:2 (i.e., "Normale"). Test the quality of the coffee and the extraction time. Constantly adjust the dial to make the powder reach a perfect thickness.

A few more words are needed here. First, take off the dial, screw off the ratchet, and use a 3mm drill to get through the end of the copper screw sleeve. Conversely, from the other end (the bearing end), hit with a 3.5mm bit until it touches the copper screw sleeve. Do not get through the copper screw sleeve. Tap from one end of the copper screw sleeve with a 4mm tap. Then the plastic core of the fixed bearing is sawed off with a hacksaw blade. Secure the disc, dial and ratchet together with two small screws. Remove the two retaining screws from the ground cover. Assemble: screw the ratchet core into the cover plate and install the locating pin at the same time. With a 4mm long screw, first fix the pointer, screw in from one end of the disc, pass through the core of the ratchet, then connect the core of the bearing, tighten the screw, and then return to two turns. Rotate to the inner side of the bearing and cover flat. If the screw is too long, it needs to be sawed off. Finally, the cover of the standby ditch is installed back with the original screw.

It should be noted that when the dial and ratchet are fixed together, pay attention to adjust the zero position. It's best to mark it when you remove the ratchet. In this way, the original dial is used for coarse adjustment. The middle screw is adjusted infinitely. The fine-tuned pointer is the minute hand of the waste electronic clock.

My Zhenghuang M520A was bought for Mo soybean powder last year. The powder box is a stainless steel cup, which avoids static electricity completely. Its disadvantage is that there are more residual powder.
