Before use:
Ensure the blade type and specification are suitable for the material being cut. Inspect for cracking, segment detachment, undercutting of the steel core or uneven wear. Confirm correct rotation direction and bore compatibility with the machine spindle. Wear appropriate PPE and ensure machine guards are correctly fitted.
During use:
Do not apply excessive force. Allow the blade to cut at its designed speed and take regular cooling breaks. If cutting performance drops significantly, reassess material suitability. Secure the material firmly and regularly inspect the blade for damage.
Wet cutting:
If wet cutting is used, ensure a continuous and adequate water supply to both sides of the blade.
