Common Signs Replacement Is Needed
Replace the blade insulator if you notice:

Installation & Service Notes
Disconnect the mower from its power source or remove the battery before servicing. Block the blade with a piece of wood to prevent rotation, then remove the blade retaining hardware. Remove the damaged 241381-01 Blade Insulator and inspect the blade, spacer (092715-00), and mounting hardware for wear or damage. Clean the mounting surfaces before installing the new insulator in the correct orientation. Reinstall the blade and all hardware according to the manufacturer's specifications, ensuring the blade is properly aligned and securely tightened before returning the mower to service.
Important: Always verify your mower model and original part number before ordering. Inspect the blade, spacer, and retaining hardware whenever the blade assembly is removed, and replace worn components as needed. Use genuine OEM Black & Decker replacement parts to maintain factory fit, proper blade alignment, and reliable mowing performance.
