CARBURETOR ADJUSTMENT

WARNING:

Keep others away

when making idle speed adjustments.
The trimmer head, blade or any op-
tional attachment 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, blade 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 fol-
lowing conditions:

S

Engine will not idle when the throttle is
released.

S

The trimmer head, blade or optional
attachment 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 adjust-
ments. 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,
blade or optional attachment moving
or spinning (idle too fast) or 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, blade
or optional attachment moves or
spins at idle.

WARNING:

Recheck the idle

speed after each adjustment. The
trimmer head, blade or optional at-
tachment must not move or spin at
idle speed to avoid serious injury to
the operator or others.
