WSA 40 Water Supply for TS / TSA (With Battery & Charger)

The STIHL WSA 40 provides reliable water delivery for clean wet cuts, even where no water supply is available. Ideal for landscaping, civil engineering, and road construction, it reduces dust and cools the cutting wheel for smoother, safer work.

Consistent Water Flow: A robust air‑compressor pump maintains steady pressure throughout the battery runtime, ensuring predictable performance and effective dust binding from start to finish.

Ready to Use: Supplied with a 10‑litre tank, level indicator, pressure relief valve, 4 m hose, pump head, STIHL AS 2 battery and AL 1 charger, so you can get to work immediately.

Customisable Pressure: Stepless adjustment from 1.5–2.5 bar lets you set the ideal flow. The system shuts off automatically when the tank is empty or inactive, saving battery life and preventing waste.

Easy to Carry & Monitor: An LED charge indicator shows remaining battery power at a glance, while the soft‑grip handle ensures comfortable transport around the job site.

Universal Compatibility: Works seamlessly with all STIHL petrol and battery cut‑off machines, making it a versatile addition to any professional kit.

Versatile Pump Head: The included PKA 30 pump head also fits the manual STIHL pressurised water tank and the STIHL SG 21 and SG 31 sprayers for added flexibility.

Built for Daily Use: Engineered for tough environments, the PKA 30 pump head is IPX4 splash‑proof and internally tested for reliability in harsh weather conditions.
