STIHL WSA 40 Cordless Pressurised Water Container (Kit)

STIHL WSA 40 Kit: Provides Efficient Water Delivery to STIHL Disc Cutters

On busy sites, a steady water supply is essential for safe and accurate cutting. The STIHL WSA 40 Cordless Pressurised Water Container is designed to provide automatic water delivery to your STIHL cut-off machine, without the need for manual pumping. Compact, practical and battery powered, it offers a reliable solution when no mains water source is available.

Developed for professionals in construction, civil engineering and landscaping, this pressurised water system supports clean wet cutting wherever the job takes you. By binding dust particles and cooling the cutting wheel, it helps maintain performance and improve working conditions.

Automatic Pressure for Continuous Water Flow

At the heart of the WSA 40 is a battery-powered pump head that maintains constant pressure throughout operation. It automatically supplies water at the selected setting, so there is no need to stop and manually repressurise the tank.

Operating pressure can be adjusted between 1.5 and 2.5 bar, or 22 to 36 psi, using a simple dial. This variable control allows you to match output precisely to the task, ensuring consistent wet cutting while helping manage water consumption effectively.

The pump head also features a built-in sleep mode. If it detects inactivity or an empty container, it enters standby to conserve battery life. This intelligent function supports longer working periods and reduces unnecessary energy use.

10-Litre Transparent Tank for Easy Monitoring

The STIHL WSA40 is equipped with a robust 10-litre transparent water tank. The clear design allows you to monitor water levels at a glance.

A funnel-shaped opening makes filling straightforward, even in demanding site conditions. A clear level indicator helps prevent overfilling, while the integrated pressure relief valve enhances safety during operation.

Supplied with a 4-metre water hose and standard coupling, this is a system that provides practical reach and simple connection to compatible STIHL machines.

Built for Professional Environments

Working outdoors often means dealing with changing weather. The STIHL WSA 40 water container is IPX4 rated, offering protection against splash water from all directions. This certification means it’s suitable for daily use in all conditions.

A protective cover shields the pump head’s battery from water, dust and site debris. Combined with the machine’s durable overall construction, this ensures dependable performance in demanding environments.

Despite its impressive capability, the WSA 40 weighs just 3.1 kg (dry), making it easy to transport around site. A soft-grip carrying handle enhances user comfort, while the LED charge-level indicator allows you to check remaining battery capacity and plan charging in advance.

Consistent Performance with Constant Power

Many cordless tools gradually lose strength as the battery discharges. With STIHL’s Constant Power technology, output remains stable throughout the entire battery cycle. This ensures that water delivery stays consistent from the first cut to the last.

The sound pressure level at the operating position is just 69.2 dB(A), contributing to a pleasanter working environment.

Versatile Integration Across the STIHL Range

The WSA 40’s battery-powered pump head can be detached from the tank and used with other compatible STIHL products, including the STIHL SG 31 sprayer, SGA 30 sprayer, and TS pressurised water tank.

This adaptability allows professionals to use one intelligent system to serve multiple applications across their worksite.

What’s Included in the Kit

The STIHL WSA 40 Cordless Pressurised Water Container Kit includes the transparent 10-litre water tank, battery-powered pump head, pressure relief valve, 4-metre water hose with standard coupling, STIHL AS 2 battery, and AL 1 standard charger—everything required to get started.

With the AS 2 battery, working time can reach up to 30 minutes on a single charge. This equates to around five full tanks of water when using a disc cutter, or between ten and twelve tanks when the pump head is paired with compatible sprayers.
