1. Diamond saw blades, if not used immediately, it should be flat or hanging it bore, flat diamond saw blade cannot be piled up on other articles or foot, and pay attention to moisture-proof, corrosion-proof.

2. When no longer sharp, diamond saw blade cutting surface rough, grinding must be carried out promptly. Grinding does not change the original angle, and destruction of dynamic balance.

3. Diamond blade diameter correction, positioning hole processing must be carried out by the manufacturer. If poor processing and may affect the product performance, and potentially dangerous, reaming cannot exceed the aperture 20mm in principle, so as not to affect the balance of stress.
