A tool for working in confined spaces. The expanded guard adjustment range of the TS 440 allows greater access in challenging cuts such as the bottom portions of walls, cutting in corners and cutting the underside of in-ground pipes. This expanded guard adjustability is made possible due to the sensor-activated STIHL Quickstop® wheel brake technology. The first cut-off machine in the world equipped with the technology capable of stopping the rotation of the cutting wheel in fractions of a second if kickback occurs. Only available at specially trained dealers.
