3.0 Applications
Typical applications for the U.S. SAWS JS SERIES SAWS would be joint cleanout and trench cutting. The
saw uses dry cut diamond blades in either 8" diameters or 10" diameters with an allowable maximum depth
cut of 3". The blade rotates in an upward direction allowing for easy dust collection when connected to an
appropriate vacuum system. The machine should always be operated with a dust collection system and in a
well-ventilated area due to carbon monoxide fumes emitted from the gasoline engine.
