MAINTENANCE ADJUSTING THE IDLE SPEED NOTE: Careless adjustments can seriously damage the unit. A qualified service dealer should make carburetor adjustments. WARNING: The cutting head may spin during idle speed adjustments. Wear protective clothing and observe all safety instructions to prevent serious personal injury. If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows: 1. Start the engine. Refer to Starting and Stopping. 2. Release the throttle control and let the engine idle. If the engine stops, use a small Phillips screwdriver to turn the idle speed screw clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly (Fig. 24). Idle Speed Screw 3. If the engine is idling too quickly, turn the idle speed screw counterclockwise, 1/8 of a turn at a time (as needed) to reduce the idle speed (Fig. 24). Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine problems. If not, and any of the following conditions are true, take the unit to a qualified service dealer: • the engine will not idle Fig. 24 • the engine hesitates or stalls on acceleration • there is a loss of engine power MAINTAINING THE SPARK PLUG 1. Stop the engine and allow it to cool. Grasp the spark plug boot firmly and pull it from the spark plug. 2. Clean around the spark plug. Remove the spark plug from the cylinder head with a 5/8-inch socket, turning counterclockwise. WARNING: Do not sand blast, scrape or clean spark plug electrodes. Grit in the engine could damage the cylinder. 3. Inspect the spark plug. If the spark plug is cracked, fouled or dirty, replace it with a replacement part #753-06193, a Champion RDJ7J or an equivalent spark plug. 4. Use a feeler gauge to set the air gap at 0.025 in. (0.635 mm) (Fig. 25). 5. Install the spark plug in the cylinder head. Tighten the spark plug with a 5/8-inch socket, turning it clockwise until snug. NOTE: If using a torque wrench, torque to: 110-120 in.•lb. (12.3-13.5 N•m). Do not over tighten. 6. Reattach the spark plug boot. 0.025 in.

Use a small brush to clean 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. 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. • Lock up the unit 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. 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. 4. Thoroughly clean the unit and inspect it for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. Preparing the Unit for Use after Long-term Storage 1. Remove the spark plug and drain all of the oil from the cylinder.
