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.
Idle Speed Adjustment
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.
