Ryobi Ryobi RY40260 40V Expand-It Cordless String Trimmer GUARD BROKEN Error Fix: Line Cutter Guard Broken or Missing

The plastic guard that mounts around the trimmer head is broken, missing, or the line cutter on the guard is damaged. The guard serves two critical functions: it protects the operator from flying debris thrown by the spinning line, and the small blade on the edge of the guard cuts the trimmer line to the optimal length. Without the guard, line will extend too far (reducing motor performance and increasing the chance of line breakage) and debris will be thrown upward toward the operator. Do NOT operate the trimmer without the guard in place — it is a safety component. Replacement guards are available through Ryobi parts and are specific to the attachment model. Installation is typically tool-free — the guard clips or bolts onto the attachment housing. If only the line cutter blade on the guard is damaged (the small metal blade on the edge), it can often be replaced separately without replacing the entire guard.
