Lubricate the throttle cable core with a silicone spray lubricant. 38 STORAGE Fuel Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum deposits that clog the fuel system. If the gasoline in your tiller deteriorates during storage, you may need to have the carburetor and other fuel system components serviced or replaced. The*length of time that gasoline can be left in your fuel tank and carburetor without causing functional problems will vary with such factors as gasoline blend, your storage temperatures, and whether the fuel tank is partially or completely filled. The air in a partially filled fuel tank promotes fuel deterioration. Very warm storage temperatures accelerate fuel deterioration. Fuel deterioration problems may occur within a few months, or even less if the gasoline was not fresh when you filled the fuel tank. The Distributor’s Limited Warranty does not cover fuel system damage or engine performance problems resulting from neglected storage preparation. You can extend fuel storage life by adding a gasoline stabilizer that is formulated for that purpose, or you can avoid fuel deterioration problems by draining the fuel tank and carburetor. Adding a Gasoline Stabilizer to Extend Fuel Storage Life When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank will promote fuel deterioration during storage. If you keep acontainer of gasoline for refueling, be sure that it contains only fresh gasoline. 1. Add gasoline stabilizer following manufacturer’s instructions. 2. After adding a gasoline stabilizer, run the engine outdoors for 10 minutes to be sure that treated gasoline has replaced the untreated gasoline in the carburetor. 3. Stop the engine, and turn the fuel valve to the OFF position. 39 STORAGE Draining the Fuel Tank and Carburetor 1. Place an approved gasoline container below the carburetor, and use a funnel to avoid spilling fuel. 2. Loosen the carburetor drain screw, then move the fuel valve to the ON position. A WARNING Gasoline is highly flammable and explosive. You can be burned or seriously injured. Never use gasoline to clean engine parts. Use a nonflammable solvent. 3. After all the fuel has drained into the container, tighten the drain screw securely. 40 STORAGE Engine Oil 1. Change the engine oil (see page 28). 2. Remove the spark plug (see page 33). 3. Pour a teaspoon (5 -10 cm3) of clean engine oil into the cylinder. 4. Gently pull the starter grip several times to distribute the oil in the cylinder. 5. Reinstall the spark plug. 6. Pull the starter grip slowly until you feel resistance, then return the starter grip gently. This will close the valves so moisture cannot enter the engine cylinder. 41 STORAGE STORAGE PRECAUTIONS If your tiller will be stored with gasoline in the fuel tank and carburetor, it is important to reduce the hazard of gasoline vapor ignition. Select a well ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated. If possible, avoid storage areas with high humidity, because that promotes rust and corrosion. Unless all fuel has been drained from the fuel tank, leave the fuel valve in the OFF position to reduce the possibility of fuel leakage. Place the tiller on a level surface. Tilting can cause fuel or oil leakage. With the engine and exhaust system cool, cover the tiller to keep out dust. A hot engine and exhaust system can ignite or melt some materials. Do not use sheet plastic as a dust cover. A nonporous cover will trap moisture around the tiller, promoting rust and corrosion. REMOVAL FROM STORAGE Check your tiller as described in the BEFORE OPERATION chapter of this manual. If the fuel was drained during storage preparation, fill the tank with fresh gasoline. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. Gasoline oxidizes and deteriorates over time, causing hard starting. If the cylinder was coated with oil during storage preparation, the engine may smoke briefly at start-up. This is normal. 42 TRANSPORTING BEFORE LOADING If the engine has been running, allow it to cool for at least 15 minutes before loading the tiller on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials. Always turn the ignition switch to the OFF position. Make sure to turn the fuel valve OFF. LOADING AND UNLOADING If a suitable loading ramp is not available, two people should lift the tiller on and off the transport vehicle while holding the tiller level. Position the tiller so it sits flat on the bed of the transport vehicle. Tie the tiller down with rope or straps. Keep the tie-down rope or straps away from the controls, adjustment levers, cables, and the carbureto...
