Key Features
- Factory-Original Construction — Manufactured to Husqvarna's OEM specifications, this engine cover matches the original material grade, geometry, and mounting configuration of the factory-installed component.
- Direct Bolt-On Replacement — Designed to mount using the existing hardware and attachment points on the FS513, FS520, and FS524, making the swap straightforward for any competent technician.
- Broad FS-Series Compatibility — A single part number covers all three FS513, FS520, and FS524 floor saw models, simplifying parts sourcing across your fleet.
- Engine Protection Restored — A properly fitted engine cover shields internal components from concrete dust, debris, and incidental contact — critical in the demanding environments where floor saws operate.
- Structural Integrity Over Time — As a genuine OEM part, this cover maintains the fit tolerances needed to stay securely in place under vibration and repeated use, avoiding the gaps or rattles that can allow debris ingress.
The engine cover on a floor saw serves as a primary protective barrier between the power unit and the harsh jobsite environment. It shields the engine from concrete dust, water, and physical impact during cutting operations — all of which are present when a floor saw is at work. A cracked, broken, or missing cover leaves the engine exposed to debris ingress and damage, and may also present a contact hazard around moving components. Replacing a damaged cover promptly restores that protection and keeps the machine running in a safe, serviceable condition.
