Wacker Neuson’s cut-off saws are designed for professional users looking for high performance output. The BTS 630 and BTS 635S saws feature an innovative air filter concept that extends service life and reduces downtime, the maker says. The BTS 630 weighs 24 pounds and has a 12-inch blade diameter with .08 inch arbor. The BTS 635S has a 14-inch blade diameter, 1-inch arbor, weighs 24.9 pounds and offers a soft-start option that includes a spring system that supports the starter mechanism and reduces the effort required to pull the starter rope. A three-stage air filter system includes a cyclonic filter, a foam, pre-filter and a paper filter designed to last longer than comparable filters and reduce maintenance, downtime and lifecycle costs. www.wackerneuson.us/en/wacker-neuson-usa/home.html
