1. If the saw blade is not used immediately, it should be laid flat or hung by using the inner hole, and other items or feet should not be stacked on the flat saw blade, and attention should be paid to moisture-proof and rust-proof.
2. When the saw blade is no longer sharp and the cutting surface is rough, it must be resharpened in time. Regrinding cannot change the original angle and destroy the dynamic balance.
3. The inner diameter correction of the saw blade, the processing of the positioning hole, etc., must be carried out by the factory. If the processing is poor, it will affect the use effect of the product, and it may be dangerous, and the reaming should not exceed the original aperture of 20mm in principle, so as not to affect the balance of stress
