ICS, the inventor of Diamond Chain Technology (DCT) for cutting concrete and other aggregate material, released the 633F4 concrete chain saw, the first gas-powered saw to use their new FORCE4 diamond chain. Designed to be the strongest diamond chain on the market, the difference is easy to spot: a much larger chassis provides 50 percent more tensile strength than standard diamond chain. The 633F4 gives the superior strength of FORCE4 the portability and ease-of-use that is a trademark of ICS gas-powered concrete chain saws. Based on the popular 101 cc, 6.5 hp 633GC concrete chain saw, the F4 package comes standard with a FORCE4 sprocket, FORCE4 14- or 16-inch guidebar, and ProFORCE diamond chain. Like all ICS gas-powered concrete chain saws, the 633F4 features slurry-resistant crankshaft sealing, dust-proof air filtra-tion, and water-resistant electronic ignition. A wet cutting system – that can be supplied by a standard garden hose – reduces hazardous dust; a built-in WallWalker provides leverage to reduce fatigue and extend chain life. The 633F4 is able to plunge cut up to 16 inches deep and make perfectly square openings with no overcuts.
