Setup, Compatibility & Care
Compatibility Check: Before purchasing, verify that your trimmer head is an Autocut 25-2 or C25-2 model and that your Stihl brushcutter is one of the compatible series (e.g., FS55, FS56, FS80, FS90). The part number 0000-997-1501 should match your replacement needs.
Setup: Installation involves carefully disassembling the trimmer head. This typically includes removing the spool, spring, and retainer. Clean any debris from the housing before inserting the new helical spring in its correct orientation. Reassemble the trimmer head components in reverse order, ensuring the spring is seated properly to function.
Care: The helical spring itself requires no special maintenance beyond ensuring it is correctly installed. Keep the trimmer head clean from dirt and grass clippings to prevent undue stress on the internal components, including the spring.
