STIHL WSA 40 Battery Water Tank

Make wet cutting easier and more efficient with the STIHL WSA 40 Battery Water Tank. Designed for use with STIHL cut-off machines, this mobile battery-powered water supply helps deliver clean, consistent water flow wherever the job takes you, even on worksites without access to a water connection.

Ideal for landscaping, civil engineering, roadwork, and construction crews, the WSA 40 uses a robust compressor pump to supply water to the cutting wheel. This helps cool the wheel during cutting while reducing dust for cleaner, more controlled work. It also helps make concrete cutting more manageable for one person, since there is no need for a separate manual water source.

This practical set includes a 10-litre tank, water hose, pump head, STIHL AS 2 battery, and STIHL AL 1 charger, so you have everything needed to get started right away. Adjustable pressure from 1.5 to 2.5 bar lets you match the water output to the task, while automatic shutoff helps preserve battery life when the tank is empty or the unit is not in use.

With an LED charge indicator and a comfortable soft-grip handle for transport, the WSA 40 is a smart jobsite solution for cleaner, more convenient wet cutting.
