Why choose the FSA400 cordless clearing saw?
Outstanding cutting performance
With a 2 kW EC motor and a cutting diameter of 520 mm, the fsa400 delivers strong, steady power to handle thick vegetation and woody growth. The automatic RPM adjustment intelligently matches blade speed to the chosen cutting tool for energy-efficient operation and maximum performance.
Comfortable and ergonomic design
Equipped with a bike handle and ergonomic double harness, the FSA400 allows for smooth sweeping movements over large areas, reducing fatigue and improving control. The adjustable handle can be set to suit your working height, ensuring the best possible posture during long jobs.
Flexible cutting tool options
Supplied as standard with the AutoCut 46-2 mowing head, the fsa400 can also be fitted with a range of STIHL cutting tools, including TrimCut, DuroCut, PolyCut heads, as well as metal GrassCut blades, BrushCut knives, ShredCut blades, and WoodCut circular saw blades for tougher clearing tasks.
Durable and reliable for professional use
Key components like the stainless steel mesh air filter, robust battery casing, and large 28 mm diameter aluminium shaft ensure long service life even in demanding conditions. The filter is easy to remove and clean to keep your tool performing at its best.
Quiet, low-vibration operation
The STIHL anti-vibration system significantly reduces vibrations transmitted to your hands and arms, making the fsa400 more comfortable to use for extended periods. It’s also quiet enough for work in noise-sensitive areas such as residential sites or near public facilities.
Smart and weather-ready
The FSA400 is IPX4 certified for use in wet conditions and features an LED charge-level indicator for quick battery checks. It’s also ready for the STIHL Smart Connector 2 A, so you can monitor tool usage and maintenance via the STIHL connected system.
