CARBURETOR ADJUSTMENT
_.WARNING: Keep others away
when making idle speed adjustments.
The trimmer head or any optional at-
tachment will be spinning during most of
this procedure. Wear your protective
equipment and observe all safety pre-
cautions. After making adjustments, the
trimmer head or any optional attach-
ment must not move/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 or optional attach-
ment moves/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 or
optional attachment moving or spin-
ning (idle too fast) or 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 or optional attachment
moves or spins at idle.
_,WARNING: Recheck the idle
speed after each adjustment. The
trimmer head or optional attachment
must not move or spin at idle speed to
avoid serious injury to the operator or
others.
