ICS Blount introduces the 680GC gas-powered concrete chain saw that features improvements to carburetion, the starting system and airflow. The saw weighs 21 pounds and requires standard garden hose water pressure for its wet-cutting system. Its 80-cc, 2-stroke engine generates about 6 hp and the unit features special seals and filtration to protect key components from harsh environments in concrete cutting. ICS also offers the 680GC with its RentMax diamond chain system. Available with either 12- or 14-inch guide bars, the unit is able to plunge cut to 14 inches and make square corners with no overcuts in reinforced concrete, natural stone and masonry.
