FS 520 Walk-Behind Concrete Saw

The FS 520 is a compact, yet powerful walk behind concrete saw built for professional contractors who demand both performance and maneuverability. Designed with user comfort in mind, the FS 520 combines ergonomic controls, a well-balanced frame, and innovative engineering to take on demanding concrete and asphalt cutting jobs. Whether you’re working on a construction site, city street, or residential driveway, the FS 520 delivers deep, precise cuts with ease.

Engine Power That Matches the Task

Available with engine options ranging from 13 to 24 hp, the FS 520 gives operators the flexibility to choose the right power level for their specific cutting needs. The saw supports blades up to 20 inches in diameter, offering a cutting depth of up to 7.7 inches. Its efficient power transmission ensures stable torque to the blade shaft, making it suitable for a wide range of applications, from light surface cuts to deeper trenching in harder materials. As a flat saw, it performs exceptionally in both performance and control.

Adaptable for Multiple Applications

The FS 520 is built for more than just concrete—it’s also a reliable paver saw and road saw. On urban paving projects, it cleanly slices through precast slabs and decorative pavers with minimal vibration. As a road saw, it delivers the cutting speed and depth needed for service patching and utility access in asphalt or concrete surfaces. Despite its compact size, the FS 520 excels in high-demand environments where agility and power are equally important.

Ergonomics and Operator Focused Features

Operator comfort and control are central to the FS 520’s design. With a clear focus on ergonomics, the saw features adjustable handlebars, intuitive controls, and low vibration output for extended use with less fatigue. The well-balanced frame and smart weight distribution enhance cutting accuracy and reduce user strain, especially during long or repetitive jobs. Its straightforward control layout ensures new and experienced users can operate it with confidence.
