CARBURETOR IDLE SPEED
ADJUSTMENT
WARNING:
Keep others away when
making idle speed adjustments. The trimmer
head or any optional attachment will be spin-
ning during most of this procedure. Wear your
protective equipment and observe all safety
precautions. After making adjustments, the
trimmer head or any optional attachment
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 following conditions:
S
Engine will not idle when the throttle is
released.
S The trimmer head or any optional
attachment moves/spins at idle.
Make adjustments with the unit supported 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 ad-
justments. Keep all parts of your body away
from the cutting attachment and muffler.
To adjust idle speed:
Allow engine to idle. Adjust speed until engine
runs without trimmer head or any optional at-
tachment moving or spinning (idle too fast) or
engine stalling (idle speed too slow).
S
Turn idle speed screw clockwise to increase
engine speed if engine stalls or dies.
S Turn idle speed screw counterclockwise to
decrease engine speed if trimmer head or any
optional attachment moves or spins at idle.
WARNING:
Recheck the idle speed
after each adjustment. The trimmer head or
any optional attachment must not move or
spin at idle speed to avoid serious injury to the
operator or others.
