The TS 410 A (EWC) Cutquik comes with electronic water control (EWC) for greater user control over the flow of water to the cutting surface. With a conveniently mounted keypad, the operator adjusts water flow during use, while the saw remembers the last setting used. EWC stops the flow of water at idle speeds and starts it automatically when the throttle is engaged. Anti-vibration technology and a lightweight, compact design improves user comfort and maneuverability. Stihl. 800-467-8445.
