Air Filter Screws Air Filter Cover MUFFLER AND SPARK ARRESTING SCREEN WARNING: The muffler on this prod- uct contains chemicals known to the State of California to cause cancer. WARNING: Muffler is very hot during and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so. 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 require any service. After 50 hours of use, we recommend that your muffler be serviced or replaced by your autho- rized service dealer. REPLACE SPARK PLUG Replace the spark plug each year to ensure the engine starts easier and runs better. Set spark plug gap at 0.025 inch. Ignition timing is fixed and nonadjustable. 1. Twist, then pull off spark plug boot. 2. Remove spark plug from cylinder and dis- card. 3. Replace with Champion RCJ-6Y spark plug and tighten securely with a 3/4 inch socket wrench. 4. Reinstall the spark plug boot. SERVICE AND ADJUSTMENTS LINE REPLACEMENT 1. Remove spool by firmly pulling on tap button. 2. Clean entire surface of hub and spool. 3.

The trimmer head will be spinning during this procedure. Wear your protective equipment and observe all safety precautions. 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 released. 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 adjustments. 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 stalling (idle speed too slow). S Turn idle speed screw clockwise to increase engine speed if engine stalls or dies. S Turn idle speed screw counterclockwise to decrease engine speed. Hub Line exit hole 5. Wind the line evenly and tightly onto the spool. Wind in the direction of the arrow found on the spool. 6. Push the line into the notch, leaving 3 to 5 inches (7 -- 12 cm) unwound. 7.
