As a direct Husqvarna OEM part, it is manufactured to the exact specifications required for proper fit and function on the FS400LV.

Key Features
- OEM-Rated Gas Pressure — manufactured to Husqvarna's specified compression and extension force, ensuring the spring performs exactly as the machine was engineered to require.
- Direct Drop-In Replacement — engineered to match the original mounting points and travel length on the FS400LV, allowing straightforward installation without modification.
- FS400LV Floor Saw Fitment — confirmed compatibility with the FS400LV walk-behind floor saw, giving you confidence when ordering by part number 543074526.
- Controlled Lid or Cover Movement — a properly functioning gas spring provides smooth, assisted opening and holds covers or access panels securely in position during blade changes and maintenance.
- Operator Safety During Servicing — a worn or failed gas spring can cause covers to drop unexpectedly during maintenance; replacing it promptly helps protect the operator and the machine.
A gas spring is a sealed pneumatic strut that uses compressed gas — typically nitrogen — to generate a controlled, consistent force across its range of travel. On the FS400LV floor saw, it supports the controlled opening and holding of an engine cover, blade guard housing, or access panel, keeping it raised safely while the operator works. When a gas spring loses its charge or its seals degrade, the supported panel can drift closed or fail to stay open, creating a potential hazard and complicating routine service work. Replacing the Gas Spring with a genuine OEM unit restores the smooth, predictable operation that safe maintenance depends on.
