The Husqvarna 542204151 Throttle is a genuine OEM component designed for the FS513, FS520, and FS524 floor saws. As a factory-sourced part, it meets the exact specifications Husqvarna engineers built into these machines, ensuring the throttle operates with the same precision as the original. This throttle is a direct replacement for the FS513, FS520, and FS524 floor saw lineup, making it straightforward to restore proper engine speed control. DHS Equipment supplies this part to help keep your floor saw running at full operational capacity.
Key Features
- Genuine OEM Specification — Sourced directly from Husqvarna, this throttle matches the exact resistance, travel, and response characteristics engineered for these floor saws — not a generic approximation.
- Direct Drop-In Replacement — Engineered to connect and mount using the original hardware points on the FS513, FS520, and FS524, so installation follows the same procedure as the factory-fitted component.
- Broad Floor Saw Compatibility — Fits three models in Husqvarna's FS walk-behind floor saw range: the FS513, FS520, and FS524, covering a wide span of the professional flat-saw lineup.
- Restored Engine Speed Control — A correctly functioning throttle allows the operator to modulate blade speed and cutting depth precisely, which is critical when working through concrete, asphalt, or masonry slabs.
- Operator Safety Relevance — The throttle is a primary control interface; a worn or unresponsive throttle can lead to unpredictable blade speed changes during cutting, making timely replacement an important safety consideration.
The throttle controls the flow of fuel and air to the engine, allowing the operator to increase or reduce blade speed depending on the material being cut and the depth of the pass. On a walk-behind floor saw like the FS513, FS520, or FS524, precise throttle response directly affects cut quality, operator control, and overall machine safety. When the throttle becomes worn, stiff, or unresponsive, engine speed becomes difficult to regulate — leading to inconsistent cuts and increased operator effort. Replacing it with a genuine Husqvarna part restores the crisp, calibrated response these floor saws are built to deliver.
