Installation notes
Disconnect the power source and let any spinning components come to a full stop.

Torque the retaining bolt to the spec listed in your owner’s manual. Check that the blade spins freely without contacting the guard before powering back on.
Common questions
Q: Will this 8-inch blade fit my STIHL FC 91 or FC 56 C-E edger without modification?
Yes, these 8-inch edger blades are made for the STIHL FC 56 C-E and FC 91, along with FC 70, FC 111, FCB-KM, FCS-KM, and FCA 140 units listed in the compatibility details. As long as your edger is one of those listed models and uses the standard 8-inch blade setup, they should install directly without modification.
Q: Can I use these blades on a STIHL KombiSystem attachment like the FCB-KM or FCS-KM?
Yes, these blades are intended to work with both the FCB-KM and FCS-KM STIHL straight lawn edger attachments. It’s still a good idea to compare your current blade’s diameter and mounting style to the listing before installation, especially if your attachment has been updated or repaired with non-original parts.
Q: What’s the best way to install and maintain these 8-inch edger blades so they last longer?
When installing, disconnect the spark plug or power source first, then clean the blade hub and tighten the hardware securely to the manufacturer’s spec. For longer blade life, check for bent edges after striking concrete or rocks, keep the mounting area free of packed dirt, and replace the blade once the edge is badly worn or the diameter is noticeably reduced.
