FSA 400 Cordless Clearing Saw (Power Unit) by STIHL

Very high-performance tool for professional work

STIHL FSA 400: Professional 36V Cordless Clearing Saw

The STIHL FSA 400 is the first dedicated battery-powered clearing saw from STIHL, engineered for professional landscaping and intensive grounds maintenance. Delivering power comparable to the FS 411 C-EM petrol clearing saw, it is designed for felling small trees, shredding thick plant growth, and clearing tough grass in noise-sensitive urban environments.

Built for durability and comfort, the FSA 400 features a sturdy 28mm aluminium shaft, a stainless steel filter, and a rugged battery casing. The integrated anti-vibration system significantly reduces handle vibration, protecting the operator's joints and muscles during all-day use.

Professional Performance & Efficiency

  • Intelligent EC Motor: Features Automatic RPM Adjustment to optimize energy consumption. The speed increases to 6,900 RPM when using BrushCut or PolyCut heads and adjusts to 5,000 RPM for AutoCut heads.

  • Variable Speed Control: The multi-function handle allows the operator to toggle between three speed levels without changing their grip, extending battery runtime for lighter tasks.

  • Power Boost Technology: Enables intelligent communication between the tool and battery to deliver maximum possible power for demanding applications while protecting the battery life.

  • Metal Mesh Air Filter: Ensures optimum motor cooling and a long service life; the fine mesh is easy to remove and clean.

Ergonomics & Versatility

  • Adjustable Bike Handle: Provides a smooth, wide mowing action ideal for large areas. The handle position can be adjusted quickly via a folding clamp to suit the user’s height.

  • Advanced Harness: Comes supplied as standard with the ADVANCE PLUS universal harness to distribute weight evenly across the shoulders and back.

  • Weather Resistance: Certified with an IPX4 rating, featuring encapsulated electronics that allow for safe operation in rain and wet conditions.

    • Mowing Heads: AutoCut 46-2 (Standard), TrimCut, DuroCut, and PolyCut.
