The 680GC chain saw from ICS Blount features increased airflow and a computerized ignition system that together reduce engine-operating temperature by 100 degrees. Altitude-friendly carburetion, stronger starter components and a decomposition valve have also been engineered into the 80 cc, 5.7-hp saw. The 680GC is available with either a 12- or 14-inch guidebar. ICS also introduces the RentMAX diamond chain aimed exclusively at the rental market. The low-cost RentMAX offers double bumpers that protect diamond segments, smooth cutting and simple installation. Patented SealPRO technology is incorporated to minimize stretch, which means fewer adjustments made on the jobsite. The diamond chain offers chain life up to 60 linear feet in 6-inch concrete (depending on user experience, amount of reinforcement and composition of the aggregate). ICS concrete chain saws also offer the ability to cut square openings as small as 3½ inches with no overcuts, as well as plunge cuts as deep as 24 inches.
