- Genuine OEM Specification — Manufactured by Husqvarna to the exact tolerances required for secure, correct engagement in the FS309 ignition or lock system.
- Exact-Match Replacement — Designed to drop directly into place on the FS309 floor saw, matching the original profile without any modification to the machine.
- FS309 Floor Saw Compatibility — Confirmed fitment for the Husqvarna FS309 floor saw, eliminating guesswork when sourcing this small but essential component.
- Restored Operational Security — A worn, damaged, or lost key prevents the operator from starting or securing the machine; this replacement restores full ignition and access control immediately.
- Part Number Confidence — Cross-reference 543044784 against your FS309 parts diagram to confirm this is the correct key for your machine before ordering.
The key on an FS309 floor saw controls access to the ignition switch, allowing the operator to start and shut down the machine in a controlled and secure manner. Without a correctly fitting key, the ignition cylinder cannot turn, leaving the saw inoperable. A damaged or missing key should be replaced promptly with the correct OEM part to ensure the machine can be started reliably and that operator control over the equipment is fully maintained.
