Overview of the Husqvarna FS 400 LV 20" Flat Saw
The FS 400 LV is a push‑type, all‑round petrol floor saw designed for contractors who need a reliable machine for repair cuts, expansion joints, and small to medium flat‑sawing jobs. Husqvarna emphasizes its convenient size, ergonomic handle design, and stable chassis, which together make it a strong choice for day‑to‑day cutting in concrete and asphalt.
This model is commonly supplied as SKU 967796502 in North America, pairing the FS 400 LV frame with a Honda GX390 engine and 20" blade guard. It is frequently used by concrete contractors, road repair crews, and rental houses thanks to its combination of power, depth capacity, and straightforward controls.
Key Features and Design Benefits
The FS 400 LV is engineered for productivity, stability, and operator comfort. Key features include:
-
Ergonomic adjustable handle: The handle can be set to different positions to ensure a comfortable working posture, reduce fatigue, and improve control.
-
Perfect weight distribution: Husqvarna designs the frame so weight sits over the blade for better tracking and reduced side forces, which leads to straighter cuts with less effort.
-
Patented gas raise/lower system (on many US configurations): This system reduces the force needed to raise and lower the blade, making depth adjustments smoother and easier.
-
Front pointer and clear line of sight: A front‑mounted cutting guide aids in keeping cuts straight and on‑line.
-
Integrated water tank (standard in many kits): Provides water feed to the blade to control dust and cool the segment, especially important when cutting concrete.
-
Compact push design: No complex drive system; the operator simply pushes the saw, which keeps maintenance simpler and improves reliability.
These features result in a saw that is easy to set up, intuitive to operate, and stable even at maximum cutting depth.

Applications: Where the FS 400 LV Excels
The Husqvarna FS 400 LV 20" Flat Saw is built as a true multi‑purpose walk‑behind concrete saw. Typical applications include:
-
Small road repair jobs in concrete and asphalt, cutting out damaged sections for patching.
-
Cutting expansion and control joints in new concrete slabs such as driveways, sidewalks, and interior floors (where ventilation allows gas engines).
-
Utility and trench work, cutting straight openings for pipes, conduits, and drains.
-
Cutting around manholes, catch basins, and curbs during street and parking lot repairs.
-
General sawcutting for slab demolition and removal, including cutting sections into manageable pieces.
Because it is compact and uses a 20" blade, it is ideal for contractors and municipalities that regularly perform patch work, driveway cuts, and general slab modifications but do not need a larger self‑propelled or diesel road saw.
Ease of Use, Stability, and Maintenance
The FS 400 LV’s design focuses on making concrete sawing productive and less physically demanding.
-
Adjustable handle: Helps operators of different heights maintain upright posture and better leverage while pushing the saw.
-
Perfect weight distribution: With weight centered over the blade, the saw tracks straighter and requires less side pressure to keep on line.
-
Gas raise/lower system: Reduces the effort needed to raise and lower blade depth, especially important when making multiple passes or adjustments.
-
Standard water feed: Simplifies dust management and blade cooling—just fill the tank and connect the water line to the blade guard.
-
Simple push transmission: With no complex hydrostatic drive, maintenance is limited mainly to engine service, belts, wheels, and general inspections.
The owner’s manual emphasizes proper cutting techniques—making a shallow guide cut, then increasing depth in increments (often about 2 in per pass) to reduce blade wear and machine load. Adhering to these recommendations extends blade life and helps keep the saw running smoothly.
