The Husqvarna 542204109 Locking Pin is a genuine OEM component designed for the FS513, FS520, and FS524 floor saws. Sourced directly from Husqvarna, this pin is built to the exact dimensional and material specifications required for correct operation on these machines. It is a direct replacement that installs without modification, restoring the locking function to its original specification. DHS Equipment supplies this part to help keep your floor saw operating at full capacity.
Key Features
- Genuine OEM Construction — manufactured to Husqvarna's exact metallurgical and dimensional specifications, ensuring the pin engages and retains with the same holding force as the original
- Direct Drop-In Replacement — machined to the original pin geometry so it seats correctly in the locking mechanism without rework or fitting
- Confirmed Fitment — compatible with the FS513, FS520, and FS524 floor saws; cross-reference 542204109 against your parts diagram before ordering
- Structural Integrity Restored — a worn or failed locking pin allows unwanted movement in the assembly it secures, affecting cut accuracy and machine control; replacing it restores proper retention
- Operational Safety — on a walk-behind floor saw, a correctly functioning locking pin keeps guarded or adjustable components positively secured during operation, supporting safe machine use
A locking pin is a precision retention component that holds two or more machine elements in a fixed position during operation. On floor saws such as the FS513, FS520, and FS524, locking pins are used to secure adjustable or hinged assemblies — such as blade guards, depth-adjustment arms, or folding frames — preventing unintended movement under load or vibration. When a locking pin wears, bends, or shears, the assembly it secures can shift during cutting, compromising both precision and operator safety. Replacing the pin with part number 542204109 returns the connection to its correct locked state.
