If your Stihl cordless or electric string trimmer needs a ready-to-install cutting head refill, this factory original spool arrives preloaded with durable 2.0 mm line and is manufactured to the same specifications as the parts used in assembly. It’s intended to restore cutting performance quickly, maintain proper feed and balance, and preserve compatibility with the trimmer’s bump or auto-feed mechanisms so you can get back to trimming without guesswork.

Will this spool fit my Stihl FSA56 or FSE52 trimmer?

Yes — this genuine Stihl replacement was designed specifically for the FSA56 and FSE52 models and other FSA-series trimmers that use the same spool geometry and feed method. Using OEM parts ensures correct mounting, secure locking, and reliable line feed.

• Direct OEM part number: 4008 710 4301 (also shown as 40087104301).
• Preloaded with 2.0 mm diameter trimmer line for intended models.
• Fits the standard bump/auto-feed heads used on the specified FSA trimmers.

How does the 2.0 mm line affect cutting performance?

Line diameter influences durability, cutting width and motor load; 2.0 mm is a balanced choice for light-to-medium lawn and edging tasks on battery or electric trimmers. It offers a good mix of longevity and flexibility so the motor runs efficiently while still providing clean cuts through grass and light weeds.

• Thicker than ultra-fine lines for longer wear between changes.
• Thin enough to reduce strain on compact trimmer motors and batteries.
• Consistent feed behavior with Stihl-designed heads for even cutting.

What are the installation and maintenance tips for this replacement spool?

Installation is straightforward: remove the trimmer head cover, lift out the spent spool, drop in the new OEM unit and snap the cover back in place. Keep the head clean of debris and replace the spool when line is fully worn; avoid using non-compatible line diameters to prevent feed issues.

• Follow your trimmer manual for head removal and reassembly steps.
• Inspect the spool housing for damage before installing a new spool.
• Only use 2.0 mm line in this OEM spool to ensure proper feed and balance.

Why choose an original Stihl spool instead of a third-party refill?

OEM spools are produced to the manufacturer’s tolerances and material standards, which reduces the chance of misfit, imbalance or premature wear compared with generic options. Choosing the genuine part helps preserve the trimmer’s handling and may reduce troubleshooting time related to line feeding or head vibration.

• Manufactured to Stihl’s original specifications and quality control.
• Guaranteed compatibility with the designed head mechanism and line feed.
• Supplies and balance tuned for the intended trimmer motor and frame.

Who is this for? This Stihl OEM 2.0 mm spool is aimed at owners of FSA56, FSE52 or related FSA-series trimmers who want a quick, reliable spool swap without modifying their tool. It’s ideal for homeowners and landscape professionals who prefer factory-specified replacement parts to maintain consistent cutting performance and avoid fitment issues associated with aftermarket refills.
