Key Features
- Genuine OEM Tachometer Components — Engineered to Husqvarna's exact output specifications, ensuring the replacement tachometer reads engine RPM with the same accuracy as the original unit on the FS4400.
- Complete Replacement Kit — Includes all components required for a full tachometer swap, so the repair can be completed in a single service session without sourcing individual parts separately.
- Designed for the FS4400 Floor Saw — Built specifically for the FS4400 walk-behind floor saw, matching the original mounting configuration and electrical connections of that machine.
- Restores Accurate Engine Speed Monitoring — A functioning tachometer allows operators to maintain correct cutting RPM, protecting both the blade and the engine from the wear caused by running outside the optimal speed range.
- Genuine Husqvarna Part — Backed by Husqvarna's OEM quality standard, this kit meets the same specifications as the component originally fitted to the FS4400 at the point of manufacture.
The tachometer on a floor saw gives the operator a real-time readout of engine speed, which is critical for maintaining the correct RPM during diamond blade cutting operations. Running the FS4400 at the wrong engine speed can lead to blade glazing, premature wear, or reduced cutting efficiency in concrete and asphalt. When the tachometer fails or reads inaccurately, operators lose the feedback they need to manage engine load effectively — making a properly functioning replacement essential for consistent, controlled cutting performance.
