The Husqvarna 543045904 Wrench is a genuine OEM service tool designed for the FS400LV and FS309 floor saws. As a factory-specified component, this wrench is built to the exact tolerances required for servicing Husqvarna floor saw assemblies, ensuring correct engagement with fasteners and fittings specific to these machines. DHS Equipment supplies this part to help keep your floor saw operating at full capacity.
Key Features
- Genuine OEM Specification — manufactured to Husqvarna's exact dimensional requirements, ensuring proper engagement and torque transfer on floor saw fasteners without slippage or rounding.
- Exact Tool Match — engineered specifically for the FS400LV and FS309 floor saws, fitting the precise fastener profiles these machines use rather than relying on a generic substitute.
- FS400LV and FS309 Compatibility — confirmed fitment for both the FS400LV and FS309 floor saw models; cross-reference 543045904 against your parts diagram to verify correct application.
- Correct Servicing Results — using the right tool for the job means fasteners are properly seated and torqued, protecting threads and assembly integrity during maintenance and blade changes.
- Purpose-Built for Construction Equipment — designed for the demands of a construction environment where precision servicing tools are essential to maintaining a high-cycle floor saw.
A dedicated wrench matched to a specific machine ensures that service and maintenance tasks are performed correctly, without risk of damaging fasteners or adjacent components. On walk-behind floor saws like the FS400LV and FS309, using an improperly sized or generic tool can strip fittings, compromise assembly torque, and lead to costly repairs. Having the correct OEM-specified wrench on hand means routine servicing — such as blade changes or belt adjustments — is completed cleanly and safely every time.
