10. Fill with 20W50 motor oil until oil just appears at the bottom of each transaxles’ top port (approximately 2 quarts per transaxle, 4 quarts total). Install the top port lug into each transaxle as the oil level reaches the port. 11. Reinstall and torque the top port plugs to 180 in./lbs. 12. Continue to fill the transaxles through the expansion tank until the FULL COLD line is reached (this will take approximately 23 additional ounces). 13. Reinstall the expansion tank cap by hand. Do not overtighten. Transmission Purging Due to the effects air has on efficiency in hydrostatic drive applications, it is critical to purge the system. These purge procedures should be implemented if the hydrostatic system has been opened for maintenance or additional oil has been added to the system. Resulting symptoms in hydrostatic systems may be: • Noisy operation. • Lack of power or drive after short term operation. • High operation temperature and excessive expansion of oil. • Shortened component life. Before starting, make sure the oil tank is at the proper oil level. If not, fill to the specifications outlined above. The following procedures are best performed with the vehicle drive wheels off the ground, then repeated under normal operating conditions. See Moving Machine By Hand in the Operation section for bypass linkage adjustments. 1. Disengage the brake if activated. 2. With the bypass linkage open and the engine running at fast idle, slowly move the directional control in both forward and reverse directions (5 or 6 times). As air is purged from the unit, the oil level will drop. 3. With the bypass linkage closed and the engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times). Check the oil level and add oil as required after stopping the engine. 4. It may be necessary to repeat Steps 2 and 3 until all the air is completely purged from the system. When the hydraulic drive operates at normal noise levels and moves smoothly forward and reverse at normal speeds, the hydraulic drive is considered purged. 5. After the vehicle has been used two times, the oil level should be checked while the oil is cold and adjusted accordingly. 31 LUBRICATION

Winter Storage The machine should be readied for storage at the end of the mowing season, or if it will not be in use for more 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 as regards to the sticky residues that can occur during storage. 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 a stabilizer has been added. To ready the machine for storage: 1. Thoroughly clean the machine, especially under the mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to avoid corrosion. 2. Inspect the machine for worn or damaged parts and tighten nuts or screws that may have become loose. 3. Change the engine oil; dispose of properly. 4. Empty the fuel tanks or add a fuel stabilizer. Start the engine and allow it to run until the carburetor is drained of fuel or the stabilizer has reached the carburetor. 5. Remove the spark plug and pour about a tablespoon of engine oil into the cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plug. 6. Lubricate all grease zerks, joints, and axles. 7. Remove the battery. Clean, charge, and store the battery in a cool place, but protect it from direct cold. 8. Store the machine in a clean, dry place and cover it 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 the machine performs its best the following season. WARNING! Do not store an engine with fuel in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flames, sparks, or a pilot light such as in a boiler, hot water tank, clothes dryer, etc. Handle the fuel with care. It is very flammable and can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and store far away from open flame or sources of ignition. Do not use gasoline for cleaning. Use a degreaser and warm water. 33 STORAGE
