The new electronic water control system for the STIHL TS 410 A and TS 420 A cut-off machines enables the operator to make precise adjustments to the water supply – simply with three push-buttons. The Plus and Minus buttons are used to adjust the water flow precisely to cutting requirements. And the water supply stops immediately when the Autostop button is pressed. The water supply also switches off automatically when idling. The electronic water control thus makes wet cutting convenient, efficient and more reliable.
