The STIHL TS500i is designed for superior handling during the toughest jobs. Featuring the outdoor power industry’s first electronically controlled fuel injection system for a handheld Cut-Off Saw, the TS500i has increased the power of 17% and cutting speed 15% higher, compared to the STIHL TS420. This low-emission fuel injected Cut-Off Saw provides optimal torque throughout the rpm range. No carburettor means the choke is not needed – just purge and pull the start cord.
