⒈ If the saw blade is not used immediately, it should be placed flat or hung by the inner hole. No other objects or footsteps should be stacked on the flat saw blade, and attention should be paid to moisture and rust prevention.
⒉ When the saw blade is no longer sharp and the cutting surface is rough, it must be re-sharpened in time. Grinding cannot change the original angle and destroy the dynamic balance.
⒊ The internal diameter correction and positioning hole processing of the saw blade must be carried out by the manufacturer. If the processing is poor, it will affect the product use effect and may cause danger. In principle, the hole expansion should not exceed the original diameter of 20mm, so as not to affect the balance of stress.
