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
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:
•Engine will not idle when the throttle is re- leased.
•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).
•Turn idle speed screw clockwise to in- crease engine speed if engine stalls or dies.
•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.
