CARBURETOR ADJUSTMENT
'_WARNING: Keep others away
when making idle speed adjustments.

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.
