Before start to cut, wear gloves and eyeprotection.

1. Buy the laser welding diamond cutting blade, the blade core contain cooling holes, it maybe clearly marked for dry cutting on blade.

2. Remove water tube from the cutting machine and turn off the electric water pump.

3. When start to cut, do not cut deeply at the very beginning, better cut step by step for the dry cutting. For the thick or deep cutting on concrete, keep the concrete cutting blade moving up(not cutting) and dropping down(cutting), this can let the diamond concrete cutting blade cool down.

4. Dry cutting only in large open areas, keep air flowing.
