1. If the blade is not immediately used, it should be flat or use the hole to hang it up, flat on the saw blade can not be stacked on other items or feet, and to pay attention to moisture-proof, rust-proof.
2. When the saw blade is no longer sharp, cutting surface roughness, it must be repaired in time. Grinding can not change the original angle, and damage the dynamic balance.
3. The inner diameter of the saw blade is corrected and the locating hole is processed, which must be carried out by the factory. If the poor processing, will affect the use of products, and may occur dangerous, reaming in principle can not exceed the original aperture 20mm, so as not to affect the balance of stress.
