STIHL WSA 40 Cordless Pressurised Water Container (Kit)

Consistent, Powerful Water Supply for Professional Use

The STIHL WSA 40 Cordless Pressurised Water Container delivers a steady, automatic water supply for STIHL cut-off machines, ensuring clean, accurate wet cuts on every job. Designed for professionals in construction, landscaping, and civil engineering, this cordless water tank eliminates the need for manual pumping. Its battery-powered pump head provides continuous pressure, maintaining a reliable flow even on sites without direct water access. This makes it an essential tool for creating cleaner cuts, suppressing dust, and cooling cutting wheels efficiently.

Constant Power from Advanced Battery Technology

Powered by the STIHL AS 2 battery, the WSA 40 ensures constant performance throughout the entire battery runtime. Unlike standard systems that lose pressure as power drops, STIHL’s intelligent electronics maintain consistent water output until the charge is depleted. This guarantees dependable performance, allowing you to work efficiently without interruptions. The built-in LED charge-level indicator provides an instant overview of the remaining capacity, helping you plan charging schedules and maximise productivity throughout the day.

Adjustable Pressure for Greater Control

With an adjustable operating pressure between 1.5 and 2.5 bar, the WSA 40 offers complete control over water flow. This enables precise and uniform application, improving dust suppression and blade cooling during operation. The adjustable pressure system ensures optimal performance for every cutting condition, reducing water waste while enhancing efficiency. This level of control makes the WSA 40 a valuable tool for both delicate and heavy-duty cutting tasks.

Durable, Weather-Resistant, and Practical Design

The WSA 40 is built for demanding work environments and includes IPX4 splashwater protection, allowing safe use even in wet weather. Its 10-litre transparent tank features a funnel-shaped opening for easy filling and a clear level indicator to prevent overfilling. The pressure relief valve ensures safe operation, while the 4-metre water hose with a standard coupling provides excellent flexibility and reach. A soft-grip handle makes transport comfortable, and the battery compartment cover protects internal components from dust, liquids, and debris, extending tool life.

Efficient, Easy-to-Use Functionality

Operation is simple with a one-touch power button that activates the pump instantly. The pressure adjustment dial allows quick changes during work for maximum versatility. The built-in sleep mode automatically shuts off the system when the container is empty or idle, conserving energy. The AS 2 battery delivers up to 30 minutes of runtime, providing approximately 12 tank refills per charge, depending on application and working pressure.

Flexible Compatibility Across STIHL Tools

The battery-powered pump head can be detached and used with other STIHL products such as the SGA 30 sprayer, SG 31 sprayer, and TS pressurised water tank. This compatibility makes the WSA 40 a highly versatile addition to any professional toolkit.

The STIHL WSA 40 Cordless Pressurised Water Container combines constant power, adjustable performance, and robust construction, making it the perfect solution for professionals who demand efficiency, reliability, and precision in every cut.
