Craftsman 358.79107 Trimmer User Manual


 
CARBURETOR ADJUSTMENT
_,WARNING: Keep others away
when making idle speed adjustments.
The trimmer head will be spinning dur-
ing most of this procedure. Wear your
protective equipment and observe all
safety precautions. After making ad-
justments, the trimmer head must not
move or spin at idle speed.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the fol-
lowing conditions:
Engine will not idle when the throttle is
released.
The trimmer head moves or spins at
idle.
Make adjustments with the unit sup-
ported so the cutting attachment is off
the ground and will not make contact
with any object. Hold the unit by hand
while running and making adjustments.
Keep all parts of your body away from
the cutting attachment and muffler.
Idle Speed Adjustment
Allow engine to idle. Adjust speed until
engine runs without trimmer head
moving or spinning (idle too fast) or
engine stalling (idle speed too slow).
Turn idle speed screw clockwise to
increase engine speed if engine
stalls or dies.
Turn idle speed screw counterclock-
wise to decrease engine speed if
trimmer head moves or spins at idle.
