When using a thresher, attention should be paid to the pressure of its rubber roller. If the pressure is low, the pressure will be high. The adjustment of the spring is between two and four, so this is the key to affecting the peeling effect. The machine has been adjusted to the use position range when it leaves the factory, but users should pay attention to adjusting it according to the actual situation at any time. Before operating the corn peeler, cover the protective covers of all transmission parts. Safety first regulations must be followed during operation, and the operating procedures must be strictly followed without any negligence.
