FAQ

This replacement spool is designed for Stihl string trimmers that utilize part number 4008 710 4301, specifically the Stihl FSA 56 and FSE 52 models. Please verify your trimmer head style and part number prior to ordering, particularly if your unit is equipped with an AutoCut head.
This spool is a direct replacement for Stihl part number 4008 710 4301. It is also compatible with variations written as 4008-710-4301 and 40087104301.
Typical signs include the trimmer line not feeding correctly, the spool binding or jamming inside the head, uneven line payout, damaged spool flanges, or excessive vibration caused by a worn or warped spool. If the line keeps tangling even with correct winding, the spool itself may be worn.
This spool is designed for use with 2.0 mm trimmer line, which is approximately 0.080 inch. Verify your trimmer head specification before installation to ensure the line diameter matches your specific setup.
Installation is straightforward and typically takes only a few minutes without the need for special tools. Simply remove the trimmer head cover, take out the old spool, clear any grass or debris from the housing, and seat the new spool so the line feeds through the eyelets without binding.
Before installation, inspect the trimmer head for packed grass, dirt, cracked eyelets, worn springs, or damage to the cap and housing. A new spool may not feed properly if the head is dirty or if another internal part is worn. Ensure the line exits cleanly and the spool turns freely once installed.
