1. When the cutting surface of wood becomes rough, it is caused by the dullness of the saw blade. It needs to be trimmed in time, but do not change the original angle of the saw blade or destroy the dynamic balance. Do not process the positioning hole or correct the inner diameter by yourself. If you do not process it well, it will affect the use of the saw blade and may cause danger. Do not expand the hole more than 2 cm beyond the original hole, otherwise it will affect the balance of the saw blade.

2. Storage precautions: If the saw blade is not used for a long time, the saw blade should be hung, or it can be placed flat using the inner hole, but no heavy objects can be placed on the saw blade. The saw blade should be placed in a dry and ventilated place, and attention should be paid to moisture and rust prevention.

The saw blade is the main component of woodworking machinery. The quality of the saw blade will directly affect the performance of the entire machine. If the saw blade becomes dull, the processing efficiency will become very low.
