STARTING A FLOODED ENGINE
Flooded engines can be started by placing
the ON/OFF switch in the ON position and the
choke lever in the OFF CHOKE position and
engaging the throttle lock as directed in the
STARTING A COLD ENGINE section; then,
pull the rope to clear the engine of excess
fuel. Starting could require pulling the starter
rope many times depending on how badly the
unit is flooded. If the unit still doesn’t start, refer
to the TROUBLESHOOTING TABLE or call

each use, clean the unit and labels using a
damp cloth with a mild detergent.

Air Filter
Cleaning the air filter:
A dirty air filter decreases engine perform-
ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.
1. Clean the cover and the area around it to
keep debris from falling into the carburetor
chamber when the cover is removed.
2. Remove parts as illustrated.
NOTE: Do not clean filter in gasoline or other
flammable solvent. Doing so can create a fire
hazard or produce harmful evaporative emis-
sions.
3. Wash the filter in soap and water.
4. Allow filter to dry.
5. Add a few drops of oil to the filter; squeeze
filter to distribute oil.
6. Replace parts.
INSPECT MUFFLER AND SPARK
ARRESTING SCREEN
NOTE:
THE SPARK ARRESTING SCREEN
ON THIS UNIT IS NOT SERVICEABLE.
For normal homeowner use, the muffler and
spark arresting screen will not require any ser-
vice.
After 50 hours of use, we recommend that
your muffler be replaced by an authorized
service dealer.
CARBURETOR 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 carburetor is not properly ad-
justed. Keep all parts of your body away from
the blade and muffler.
Idle Speed Adjustment
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.
