Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than full throttle.
At lower speeds, there is less engine noise and
vibration. The cutting line will last longer and will
be l ess likely to “weld” onto the spoo l.
Always release the throttle trigger and allow the
engine to return to idle speed when not cutting.
To stop engine:
S Release the throttle trigger.
S Push and hold the STOP switch in the
STOP position until the engine stops.
