Switch hands frequently to avoid irritation caused by repetitive motion and the required pressure from fingers, hand, forearm, elbow, and shoulder. I just started turning the handle. After half of the beans have been ground, it is important to regularly check that the beans are not falling into the grinder and that the ground coffee container is not overflowing. am, so I periodically adjust the contents of the container to avoid overfilling.
