STIHL WSA 40 Cordless Pressurised Water Container (Kit)

Reliable and Consistent Water Supply for Professional Cutting Tasks

The STIHL WSA 40 Cordless Pressurised Water Container is designed to provide a constant, automatic water supply for your STIHL cut-off machine, ensuring clean and precise wet cuts on-site. Perfect for professionals in construction, landscaping, and civil engineering, this powerful cordless system removes the need for manual pumping, delivering consistent performance across every job. Its battery-powered pump head ensures continuous pressure, allowing smooth, uninterrupted cutting, even on sites without direct water access.

Constant Power with Intelligent Battery Technology

The WSA 40 is powered by the STIHL AS 2 battery, offering constant power output throughout the entire runtime. Unlike conventional systems where performance drops as the battery discharges, STIHL’s advanced electronics maintain steady water pressure until the charge is complete. This ensures maximum efficiency, helping you complete cutting tasks faster and more effectively. A convenient LED charge-level indicator allows you to monitor battery capacity, so you can plan charging intervals efficiently and avoid unexpected interruptions during work.

Adjustable Pressure for Precise Application

With variable operating pressure ranging from 1.5 to 2.5 bar, the WSA 40 gives you full control over water flow. This precision ensures a uniform and efficient distribution of water, allowing for dust suppression and cooling of the cutting wheel. By adjusting the flow for each task, users can achieve optimal cutting performance while minimising water waste, helping to lower operational costs and environmental impact.

Durable, Weather-Resistant, and Easy to Use

Built for professional environments, the WSA 40 features an IPX4 splashwater protection rating, allowing reliable use in wet or rainy conditions. The transparent 10-litre tank includes a funnel-shaped design for easy filling and a level indicator to prevent overfilling. A pressure relief valve maintains safe operation, while the 4-metre water hose with standard coupling ensures compatibility and flexibility on-site. The soft-grip carrying handle makes transport comfortable, and the protective battery cover shields internal components from water, dust, and debris.

Smart Functionality and Power Efficiency

Operating the WSA 40 is effortless. A simple power button activates the pump, while a pressure control dial allows quick adjustments for different applications. A built-in sleep mode automatically shuts off the pump when the container is empty or not in use, conserving battery power. This ensures you get up to 30 minutes of continuous runtime per charge, enough for up to 12 tank refills depending on the application.

Compatible and Versatile System

The battery-powered pump head can be detached and used with other STIHL tools, including the SGA 30 sprayer, SG 31 sprayer, and TS pressurised water tank, offering versatility across multiple tasks.

The STIHL WSA 40 Cordless Pressurised Water Container delivers constant pressure, exceptional durability, and effortless operation, making it the perfect companion for professionals who demand efficiency, precision, and reliability in every job.
