CARBURETOR ADJUSTMENT
WARNING:
Keep others away when
making idle speed adjustments. The trimmer
head will be spinning during most of this pro-
cedure. Wear your protective equipment and
observe all safety precautions. After making
adjustments, the trimmer head 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 re-
leased.
S
The trimmer head moves/spins at idle speed.
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 moving or spinning
(idle speed too fast) or engine stalling (idle
speed too slow).
S
Turn idle speed screw clockwise to in-
crease engine speed if engine stalls or dies.
S
Turn idle speed screw counterclockwise to
decrease engine speed if trimmer head
moves or spins at idle speed.
WARNING:
Recheck the idle speed
after each adjustment. The trimmer head
must not move or spin at idle speed to avoid
serious injury to the operator or others.
