The STIHL WSA 40 is a mobile, battery-powered water tank that lets you make clean wet cuts anywhere—even on sites without a water supply. Ideal for landscaping, civil engineering, and roadwork, it delivers a steady water flow using a robust compressor pump to cool the cutting wheel and reduce dust.
This set includes a 10‑L tank, water hose, pump head, AS 2 battery, and AL 1 charger, so you can start working immediately. With adjustable pressure from 1.5–2.5 bar, automatic shutoff, LED charge indicator, and a soft‑grip handle, the WSA 40 is easy to use and comfortable to transport.
