CARBURETOR IDLE SPEED
ADJUSTMENT
WARNING:
Keep others away when
making idle speed adjustments. The blade
will be moving during most of this procedure.
Wear your protective equipment and observe
all safety precautions. When making adjust-
ments, use a screwdriver short enough to
keep your hands behind the handguard and
away from the blade. After making adjust-
ments, the blade must not move 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 blade moves at idle. Keep others away
when making idle speed adjustments.
Make adjustments with the unit resting on a
level surface free of debris that can be caught
in the hedge trimmer blade. Serious injury to
the operator and others can occur if the car-
buretor is not properly adjusted. Keep all
parts of your body away from the blade and
muffler.
To adjust idle speed:
Allow engine to idle. Adjust speed until engine
runs without blade moving (idle too fast) or en-
gine 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 the blade moves
at idle.
WARNING: Recheck the idle speed
after each adjustment. The blade must not
move at idle speed to avoid serious injury to
the operator or others.
