INSPECT MUFFLER AND SPARK
ARRESTING SCREEN
WARNING:
The muffler on this prod-
uct contains chemicals known to the State of
California to cause cancer.
As your unit is used, carbon deposits build up
on the muffler and spark arresting screen.
For normal homeowner use, however, the
muffler and spark arresting screen will not re-
quire any service. After 50 hours of use, we
recommend that your muffler be serviced or
replaced by your authorized service dealer.
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 ad-
justments. Make adjustments with the unit rest-
ing on a level surface free of debris that can be
caught in the hedge trimmer blade. Serious inju-
ry to the operator and others can occur if the
carburetor 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.
If you require further assistance or are unsure
about performing this procedure, contact an
authorized service
1- -800- -554- -6723.
BLADE ADJUSTMENT
The clearance between the cutting blades
must be adjusted periodically to maintain opti-
mal performance and sharp cutting.
