Overview

STIHL WSA 40 Set SA090118512 WSA 40 Battery Water Tank: Automatic and consistent mobile water supply for STIHL cut-off machines, making concrete cutting a one-man job now

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.

features

CONSTANT POWER

CONSTANT POWER, REGARDLESS OF BATTERY CHARGE STATUS. With other brands of battery tools, the performance usually decreases during work as the battery discharges. This is not the case with STIHL cordless power tools with CONSTANT POWER. Thanks to the intelligent electronics, your STIHL power tool works with consistently high power.

LED CHARGE-LEVEL INDICATOR

FOR GOOD PLANNABILITY. At the push of a button, the LED charge-level indicator will inform you at any time about your battery’s remaining capacity. This allows you to efficiently plan working hours and charge the battery in good time.

REGULATION OF OPERATING PRESSURE AND WATER FLOW

PRECISE DOSAGE. The operating pressure can be variably adjusted to achieve a uniform application of fluid which is optimal for the specific task. This can contribute to lower volumes of the fluid (e.g. pesticide) being used.
