Echo Genuine C554000080 Trimmer Line Knife Cutter 69901644330 OEM

Echo Genuine C554000080 Trimmer Line Knife Cutter 69901644330 OEM.

Restore Proper Cutting Swath & Protect Centrifugal Clutches: Genuine Echo Line Cutter

Eliminate engine bogging, clutch slippage, melted clutch springs, and ragged line advancement on your commercial string trimmer. This Genuine Echo / Shindaiwa Factory OEM Trimmer Line Cutter Knife (Part Number C554000080) is the authentic hardened steel cutoff blade engineered explicitly for Echo SRM series trimmers and PAS attachments (directly replacing prior part number 69901644330) . Operating a commercial trimmer without a sharp, rigid cutoff knife allows trimmer line to extend too far, placing excessive drag on the powerhead and dragging engine operating RPMs below the clutch engagement threshold.

Instead of struggling with soft aftermarket copy blades that bend on commercial-grade .095" or .105" line, installing this authentic factory component ensures true OEM cutting performance. Precision-stamped by Echo from high-carbon, heat-treated spring steel, this blade features a factory-ground, razor-sharp beveled cutting edge that cleanly slices through thick commercial twisted and square monofilament without fraying or jamming the trimmer head. Its precision-formed mounting flange features factory-spaced mounting holes designed to bolt directly into the recessed boss of your OEM debris shield, ensuring the line is trimmed to the exact engineered cutting radius for optimal torque and engine cooling.

This authentic factory replacement component is cataloged under Echo / Shindaiwa OEM Part Number C554000080 (Knife, Line Cutter / Cut-Off Blade / Cutter, Thread) and directly supersedes / replaces prior OEM Part Number 69901644330 (699016-44330) .

🛠️ Pro-Maintenance Tip: Watch the "Shield Mount Torque & Bevel Orientation Secret!" Bevel Orientation Secret: When bolting the C554000080 blade onto your debris shield, always verify that the beveled ground edge faces the rotating trimmer line! Installing the blade backward forces the blunt side of the steel to impact the line, which smashes rather than cuts the nylon, violently jerking the trimmer head and cracking the plastic guard boss. Mounting Screw Caution: Do not over-torque the mounting screws into the plastic shield boss. Hand-tighten until snug; overtightening strips the plastic threads in the deflector guard, requiring you to replace the entire plastic shield assembly.
