With the STIHL WSA 40 mobile battery-powered water tank you can use your STIHL cut-off machine to carry out clean wet, cuts even on construction sites without water supply, for example. For professional use in horticulture and landscaping as well as in civil engineering and road construction. The robust air compressor pump automatically delivers a consistent water supply throughout the entire battery life. This water binds dust particles and simultaneously cools the cutting wheel.

In addition to the robust 10-litre capacity water tank, level indicator, pressure relief valve, 4 m water hose with standard coupling and pump head, this practical set also includes a STIHL AS 2 battery and a STIHL AL 1 charger. This means that you can start your work immediately after delivery.

The STIHL WSA 40 is easy to use and features stepless pressure adjustment between 1.5 bar and 2.5 bar, so the flow volume can be adapted to suit specific applications. The WSA 40 automatically switches off when the tank is empty or if the power tool is not used for an extended period of time. This contributes to longer battery life. In addition, you can always see how much battery power you have left thanks to the LED charge-level indicator. The softgrip carry handle ensures the WSA 40 can be transported comfortably and ergonomically.

The STIHL WSA 40 battery water tank is compatible with all STIHL battery and petrol cut-off machines.
