storage Winter storage At the end of the season, the machine should be readied for storage (or if it will not be in use for longer than 30 days). Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function. Fuel stabilizers are an acceptable option to reducing sticky residues during storage. If alkylate gasoline (Aspen) is used, stabilizers are unnecessary because this fuel is stable. However, you should avoid switching between regular and alkylate gasoline as sensitive rubber components can harden. Add stabilizer to the fuel in the tank or in the storage container. Always use the mixing ratios specified by the manufacturer of the stabilizer. Run the engine for at least 10 minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if you have added stabilizer. WARNING! Never store an engine with fuel in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flame, sparks or a pilot light such as in a boiler, hot water tank, clothing drier, etc. Han­dle the fuel with caution. It is very ­flammable and careless use can cause serious damage to person and property. Drain the fuel into an approved container outdoors and far away from open flame. Never use gasoline for cleaning. Use a degreaser and warm water instead. To ready the machine for storage, follow these steps: 1. Clean the machine carefully, particularly the chassis and working equipment. Mend damage to the paint to prevent rust. 2. Inspect the machine for worn or damaged parts and tighten any nuts or bolts that may have become loose. 3. Change the engine oil; dispose of properly. 4. Open the fuel valve. Empty the fuel tank and the carburetor. Fuel tank plug and filter 8011-130 5. Close the fuel valve. 6. Remove the spark plug and pour about a tablespoon of engine oil in the cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plug. 7. Lubricate all grease nipples, joints and shafts as described in the chapter "Lubrication/Lubrication Schedule". 8. Store the machine in a clean, dry place and cover for extra protection. Service When ordering spare parts, please specify the ­purchase year, model, type, and serial number. Always use genuine Husqvarna spare parts. An annual check-up at an authorized service workshop is a good way to ensure that your machine performs its best the following season. 29
