TRANSPORTING • Allow the engine to cool before transporting. • Drain fuel from unit. • Tighten fuel cap before transporting. • Secure the unit while transporting. WARNING: To avoid serious personal injury, always turn your trimmer off and allow it to cool before you clean or maintain 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. LONG TERM STORAGE If you plan on storing the unit for an extended time, use the following storage procedure: 1. Carefully drain the fuel tank by running the unit dry or remove fuel cap and tip the motor housing over and drain oil/gas fuel into a container with the same 2-cycle fuel mixture. Do not use fuel that has been stored for more than 60 days. 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 1 oz. (30 ml) 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 trimmer after storage. 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. The unit is ready for storage. 11 TROUBLESHOOTING PROBLEM SOLUTION Old or improperly mixed fuel Drain gas tank and add fresh fuel mixture Improper carburetor adjustment Adjust according to the Carburetor Adjustments section or take to an authorized service dealer for an adjustment Cutting attachment bound with grass Stop the engine and clean the cutting attachment Dirty air filter Clean or replace the air filter Plugged spark arrestor Clean or replace spark arrestor Empty fuel tank Fill fuel tank with properly mixed fuel Primer bulb wasn't pressed enough Press primer bulb fully and slowly 10 times Engine is flooded Pull the starter rope while holding the throttle control Old or improperly mixed fuel Drain gas tank and add fresh fuel mixture Fouled spark plug Replace the spark plug Plugged spark arrestor Clean or replace spark arrestor The outside temperature is below 40.
