Do not force the blade to cut. Allow the diamonds to perform cutting through the material. Slower cuttinghelps eliminate chipping on the cut edge.● For thick material (3cm or 1-1/4") step-cutting is highly recommended.● Wet cutting is required for the larger blade sizes (6”, 8” and 10”).● Take appropriate steps to assure personal safety when performing any cutting application.● Review operations manual of the power tool to assure proper usage.
