If you find that the saw blade you are using has the following problems, please take it down and sharpen it immediately. Do not continue to use it, otherwise it will cause burning, burrs, edge collapse, or even flying teeth or rotten teeth.

1. When sawing burrs and roughness occur, it is necessary to sharpen it immediately.

2. When the blade of the alloy cutter head is worn to 0.2mm, it must be sharpened before use.

3. When it is difficult to push the material, and the cut material shows signs of blackening and burning, it needs to be sharpened.

4. When cutting, there is an abnormal sound, which requires sharpening.

5. When cutting, the saw blade needs to be sharpened when the teeth are sticky, falling off, or breaking.

Correct use of the saw blade and timely sharpening can effectively extend the service life of the saw blade.
