STIHL WSA 40 Cordless Pressurised Water Container (Kit)

A Portable Water Supply for Disc Cutters: STIHL WSA 40 Cordless Pressurised Water Container Kit

When you’re working on construction sites or landscaping projects, clean wet cutting depends on a reliable water supply. The STIHL WSA 40 Kit is designed to deliver that supply automatically to compatible STIHL disc cutters, removing the need for manual pumping. Compact and battery powered, it offers a practical, portable solution in areas without a mains connection.

Created for professionals in construction, civil engineering and landscaping, this system supports safer, more controlled cutting. By feeding a steady stream of water to the cutting wheel, it helps suppress dust and reduce heat build-up, improving both performance and site conditions.

Controlled Water Delivery Without Fuss

The WSA 40 STIHL water container uses a battery-driven pump head to maintain pressure throughout operation. It keeps water flowing at the selected setting, allowing you to focus on the cut rather than the tank.

Pressure can be adjusted between 1.5 and 2.5 bar (22 to 36 psi) through an easy-to-use dial. This variable control enables you to match output to the demands of your work. Consistent pressure supports uniform wet cutting and helps manage water usage efficiently.

An integrated sleep function enhances energy management. If the system detects inactivity or an empty container, it automatically switches to standby mode to preserve battery life.

Large Tank with Practical Design

The robust 10-litre tank is transparent, making it simple to check water levels at a glance. This clear visibility reduces the risk of running dry mid-task.

Filling is straightforward thanks to the wide, funnel-shaped opening. A clearly marked water-level indicator helps prevent overfilling, while the built-in pressure relief valve contributes to safe operation.

A 4-metre water hose with standard coupling is included in the price, providing ample reach and straightforward connection to compatible STIHL machines.

Consistent Output with STIHL Constant Power

Cordless equipment often weakens as the battery discharges. STIHL’s Constant Power technology ensures the WSA 40 water container maintains stable performance across the entire charge cycle.

Water flow remains steady from your first cut to the last, supporting reliable dust suppression and cooling. The sound pressure level at the operator’s ear is only 69.2 dB(A), contributing to a more controlled working environment.

An LED charge-level indicator on the power head allows you to check remaining battery capacity at any time. This helps you efficiently plan recharging and avoid unexpected interruptions.

Built for Tough Outdoor Conditions

Professional users require equipment that can handle unpredictable weather. The WSA 40 is IPX4 rated, meaning it is protected against splash water from all directions. This makes it suitable for daily use in damp or rainy conditions.

A protective battery cover shields the power unit from water, dust and debris. Combined with STIHL’s A1 engineering, this ensures the water container’s long-term reliability on demanding sites.

Despite its capability, this water tank kit weighs just 3.1 kg when empty. A soft-grip carrying handle improves the user’s comfort when transporting or repositioning the tank.

Flexible System with Removable Pump Head

You can detach the battery-powered pump head from the tank and use it with other compatible STIHL equipment. It can be paired with the STIHL SG 31 sprayer, SGA 30 sprayer and TS pressurised water tank.

This versatility allows professionals to use one intelligent power head across multiple applications, increasing efficiency across big site tasks.

Complete Kit with Battery and Charger

The STIHL WSA 40 Kit includes the transparent 10-litre water tank, battery-powered pump head, pressure relief valve, 4-metre hose with standard coupling, STIHL AS 2 lithium-ion battery and an AL 1 standard charger.

With the AS 2 battery, runtime can reach up to 30 minutes on a single charge. In practical terms, this equates to around five full tanks of water when working with a disc cutter, or between ten and twelve tanks when used with compatible sprayers.

Available Accessories

Optional extras include additional AS 2 batteries and a range of advanced STIHL chargers. These include the AL 5 Hi-Speed Charger, AL 5-2 Hi-Speed Dual Charger, ALS 31 Charger and the PS 1 Power Bank and Charger.

Reliable Water Supply Wherever You Work

When a direct water source is not available, dependable wet cutting can be difficult. The STIHL WSA 40 Cordless Pressurised Water Container Kit provides a portable, automatic solution that supports cleaner cuts and improved dust control.

Add this professional water delivery system to your disc cutter today and ensure consistent, controlled performance on every job.
