The BTS 630 and BTS 635 cutoff saws feature a unique three-stage air-filter system that reduces maintenance, minimizes downtime, and improves sawing quality. The robust design includes a 4.3 kW high-torque engine, poly v-belt, and enclosed starte rope housing. With an effective vibration-damping system, hand-arm vibration is cut to under 5 m/s2, enabling operators to use the machines continuously over an eight-hour period. Wacker Neuson. 800-770-0957.
