A worn or damaged spool can reduce cutting efficiency and interfere with proper line feeding.

Installation & Service Notes

Disconnect the trimmer from the power source or remove the battery before replacing the spool.

Remove the trimmer head cap according to the manufacturer's service instructions. Remove the existing spool and inspect the spool housing, spring, and bump-feed mechanism for dirt, wear, or damage. Install the new 143684-01 Replacement Trimmer Spool, ensuring the line is routed correctly through the eyelets before reinstalling the spool cap. Verify smooth line advancement before returning the trimmer to service.

Important: Always verify your trimmer model, type number, and original part number before ordering. Use genuine OEM DeWalt replacement spools to ensure proper fit, reliable line feeding, and long-term trimmer performance.
