The Husqvarna 543850365 Gas Spring is a genuine OEM component designed for the FS309 floor saw. As a direct Husqvarna OEM part, it is manufactured to the exact specifications required for proper operation and fit on the FS309. DHS Equipment supplies this part to help keep your floor saw performing at its best.
Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact pressure and travel specifications, ensuring the gas spring delivers the correct resistive force for its application on the FS309.
- Direct-Fit Replacement — engineered to the same mounting dimensions and end-fitting configuration as the original, allowing straightforward installation with no adapters or modifications.
- FS309 Floor Saw Compatibility — verified fitment for the Husqvarna FS309 walk-behind floor saw; cross-reference part number 543850365 against your parts diagram before ordering.
- Consistent Controlled Movement — a properly functioning gas spring maintains smooth, controlled positioning of the component it supports, preventing sudden or uncontrolled movement during operation or service.
- Restored Operator Control — a worn or failed gas spring causes inconsistent or uncontrolled movement, which affects both operator comfort and machine usability; this replacement restores full intended function.
A gas spring is a sealed, pressurized strut that uses compressed gas to exert a controlled, consistent force across its range of travel. On a floor saw like the FS309, it supports and dampens the movement of a hinged or adjustable component — such as a blade guard, hood, or cutting head — holding it in position and allowing smooth, controlled opening and closing. When a gas spring loses pressure or its seal degrades, the component it supports may drop suddenly, resist movement, or fail to hold position, making the machine harder and less safe to operate. Replacing a failed gas spring restores the smooth, controlled motion the machine was designed to provide.
