Mesh Adjustment: 1. Set the powder holder and turn the adjustment nut until it stops to the right. 2. Open the lid and pour coffee beans into the hopper. Place it on a sturdy platform such as a table, hold the main unit, close the lid, turn the adjustable nut slightly to the left and turn the handle to the right to actually grind the beans until it becomes the mesh you like. *Adjustment can be checked with a little bean. Turn the adjustment nut to the left to make the mesh coarse. Even if you turn the handle to the left, it will not grind the beans correctly. 4. When the coffee beans are no longer grinded, you can finish your coffee grounds Remove the powder holder and use it. Care Instructions: When the main unit and the powder tray get dirty, always use a dry cloth. The coffee powder accumulated in the grooves inside the hopper and inside the tray can be removed with a brush.
