The Husqvarna 543850374 Gas Spring is a genuine OEM component designed for the FS309 floor saw. As a factory-original part, it is built to Husqvarna's exact specifications, ensuring proper fitment and function within the machine's hood or cover assembly. DHS Equipment supplies this part to help keep your floor saw operating as intended.
Key Features
- OEM-Specified Load Rating — manufactured to the exact extension force and stroke length required by the FS309, so the spring supports and holds panel weight correctly without over- or under-tensioning.
- Direct Bolt-In Replacement — end fittings match the factory mounting points on the FS309 floor saw, allowing a straightforward swap with no modification to brackets or hardware.
- FS309 Floor Saw Compatibility — sourced specifically for the FS309, so fitment against your parts diagram is straightforward using part number 543850374.
- Controlled Panel Support — a correctly functioning gas spring holds covers and access panels open at a safe, stable position, keeping hands free during maintenance and inspection tasks.
- Operator Safety — a failed or weakened gas spring can allow heavy panels to drop unexpectedly during service; replacing it with a genuine OEM unit restores safe, predictable panel behavior.
A gas spring is a sealed, pressurized strut that uses compressed gas — typically nitrogen — to generate a controlled, consistent extension force. In a floor saw like the FS309, it is commonly used to counterbalance engine covers, blade guards, or access panels, holding them open during blade changes, belt inspections, or general servicing. When a gas spring weakens or loses its charge, panels can become difficult to hold open or may fall unexpectedly, creating both a safety hazard and an obstacle to efficient maintenance.
For fitment verification, cross-reference 543850374 against your FS309 parts diagram before ordering. Contact DHS Equipment if you need assistance confirming compatibility.
