Remove the spring from the old inner reel (Fig. 24). 4. Place the spring in the new inner reel. NOTE: The spring must be assembled on the inner reel before reassembling the cutting attachment. 5. Insert the ends of the line through the eyelets in the outer spool (Fig. 32). 6. Place the new inner reel inside the outer spool. Push the inner reel and outer spool together. While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the spool. 7. Hold the inner reel in place and install the bump knob by turning counterclockwise. Tighten securely. AIR FILTER MAINTENANCE Cleaning the Air Filter Air Filter Cover Air Filter Housing Failure to maintain your air filter properly can result in poor performance or can cause permanent damage to your engine. 1. Open the air filter cover by unscrewing the cover screw (Fig. 33). 2. Remove the air filter (Fig. 33). 3. Wash the filter in detergent and water. Rinse the filter thoroughly and allow it to dry. 4.

Air Filter Cover Fig. 34 Hooks WARNING: The cutting attachment will spin during idle speed adjustments. Wear protective clothing and observe all safety instructions to prevent serious personal injury. If, after checking the fuel mixture and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows: 1. Start the engine and run for one minute to warm up. Refer to Starting/Stopping Instructions. Idle Adjustment Screw 2. Release the throttle trigger and let the engine idle. If the engine stops, insert a small phillips screwdriver into the idle adjustment screw (Fig. 35). Turn the idle speed screw clockwise 1/8 of a turn at a time (as needed) until the engine idles smoothly. 3. If the engine appears to be idling too fast, turn the idle speed screw counterclockwise 1/8 of a turn at a time (as needed), to reduce idle speed. Checking the fuel mixture, cleaning the air filter and adjusting the idle speed should solve most engine problems. If not and all of the following are true: Fig. 35 • the engine will not idle • the engine hesitates or stalls on acceleration • there is a loss of engine power Have the carburetor adjusted by an authorized service dealer. REPLACING THE SPARK PLUG Use replacement #753-06193, a Champion RDJ7J spark plug, or equivalent. The correct air gap is 0.025 inch (0.635 mm). 1. Stop the engine and allow it to cool. Grasp the plug wire firmly and pull it from the spark plug. 2. Clean around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8-inch socket counterclockwise. WARNING: Do not sand blast, scrape or clean electrodes. Grit in the engine could damage the cylinder. 3. Replace a cracked, fouled or dirty spark plug. Set the air gap at 0.025 in. (0.635 mm) using a feeler gauge (Fig. 36). 4. Install a correctly-gapped spark plug in the cylinder head. Tighten by turning the 5/8-inch socket clockwise until snug. If using a torque wrench torque to: 110-120 in.•lb. (12.3-13.5 N•m) Do not over tighten. CLEANING 0.025 in. (0.635 mm) Fig. 36 WARNING: To avoid serious personal injury, always turn the unit off and allow it to cool before you clean or service it. Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage plastic housing or handle. Wipe off any moisture with a soft cloth. STORAGE • Never store a fueled unit where fumes may reach an open flame or spark. • Allow the engine to cool before storing. • Store the unit locked up to prevent unauthorized use or damage. • Store the unit in a dry, well-ventilated area. • Store the unit out of the reach of children. Short Term Storage (1-2 weeks) 1. Store the unit in a horizontal position. If this is not possible, store the unit vertically with the engine at the top. Long-term Storage 1. Remove the fuel cap, tip the unit and drain the fuel into an approved container. NOTE: Do not use gasoline that has been stored for more than 30 days. Dispose of old gasoline in accordance with federal, state and local regulations. 2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the carburetor. 3. Allow the engine to cool. Remove the spark plug and put 5 drops of any high quality motor oil or 2-cycle oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug. NOTE: Remove the spark plug and drain all of the oil from the cylinder before attempting to start the unit after storage. 4. Thoroughly clean the unit and inspect for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.
