LINE CUT-OFF BLADE

This trimmer is equipped with a line cut-off blade on the
guard. The line cut off blade continuously trims the line to
ensure a consistent and efficient cut diameter. Advance line
whenever you hear the engine running faster than normal, or
when trimming efficiency diminishes. This will maintain best
performance and keep line long enough to advance properly.
