Overview
Keep your string trimmer ready for action with this pre-wound replacement spool. It is built to the same dimensions as the OEM spool, so it drops right into the trimmer head with no modifications. Aftermarket spools provide the same cutting performance as factory originals at a better value.
Key specifications
- Pre-wound replacement trimmer spool

Compatibility
This spool is designed for Stihl string trimmers as listed above. Confirm the spool part number, line diameter, and trimmer model before ordering to ensure a proper fit.
Installation notes
Remove the spool cover from the trimmer head. Extract the old spool and clean out any grass or debris. Insert the new pre-wound spool, feed the line ends through the guide holes, and reattach the cover. Verify the line extends the correct length before trimming.
Common questions
Q: Will this C 3-2 pre-wound spool fit my Stihl FSA 57, or is it only for certain mowing heads?
This spool fits the Stihl FSA 57 only if your trimmer uses the AutoCut C 3-2 mowing head, part number 4009 710 2106. It is also limited to units with the 5” serial number version, so it will not fit the 9” series.
Q: How do I install this pre-wound replacement spool in my FSE 52 without restringing the head?
Open the AutoCut C 3-2 head, remove the old spool, and clear out any grass or debris inside before inserting the new pre-wound spool. Feed the line ends through the eyelets, seat the spool correctly, and snap the cap back on securely so the auto-feed works properly.
Q: Is this replacement spool compatible with the Stihl FSA 50 and FSA 56, and does it come ready to use?
Yes, it is compatible with the Stihl FSA 50 and FSA 56 as long as they use the AutoCut C 3-2 head 4009 710 2106 and are not part of the 9” series. Since it is pre-wound, you can install it directly without manually winding trimmer line first.
