Usage Guide:
Before use
Ensure the blade type and specification are suitable for the material being cut. Inspect for cracking, segment detachment, undercutting of the steel centre, uneven wear, or other defects. Confirm correct rotation direction and bore compatibility with the machine spindle. Wear appropriate PPE, including eye protection, and ensure 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 overheating occurs, reassess material suitability. A blunt blade may be refreshed by cutting a soft abrasive material such as brick or block.
Wet cutting
If wet cutting is used, ensure a continuous and adequate water supply to both sides of the blade.
