[. . . ] To change engine oil, see the Customer Responsibilities section of this manual. ADD GASOLINE • Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Purchase fuel in quantities that can be used within 30 days to ensure fuel freshness. IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW 32° F. (0° C. ), USE FRESH, CLEAN WINTER GRADE GASOLINE TO HELP INSURE GOOD COLD WEATHER STARTING. CAUTION Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it the run until the fuel lines and carburetor are empty. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur. WARNING Fill to bottom of filler neck. Do not store, spill or use gasoline near an open flame. 24 OPERATION TO START ENGINE (See Fig. 3) When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine. • Be sure IZT (Integraded Zeroturn Transaxle) bypass linkages are in the drive position. • Sit on the seat in the operators position, release park brake lever. • For a warm engine start, the choke control may not be needed NOTE: Before starting, read the warm and cold starting procedures below. • Insert key into the ignition and turn the key clockwise to “START” position and release the key as soon the engine starts. Do not run the starter continuously for more than 15 seconds per minute. If the engine does not start after several attempts, push the throttle control into the choke position, wait a few minutes and try again. If the engine still does not start, move the throttle control back into the fast position and retry. WARM WEATHER STARTING (50° F and above) • When the engine starts, slowly pull the throttle control back until the engine begins to run smoothly. If the engine starts to run roughly, press the throttle control back forward to choke the engine for a few seconds. If the engine does not accept the load, restart the engine and allow it to warm up for one minute using the choke as described above. 25 OPERATION COLD WEATHER STARTING (50° F and below) • When the engine starts, slowly pull the throttle control back until the engine begins to run smoothly. Continue to pull back on the throttle control in small steps allowing the engine to accept small changes in speed and load, until the throttle control is completely in the fast position. If the engine starts to run roughly, press the throttle control back forward to choke the engine for a few seconds. Then continue to pull the throttle control back slowly to the fast position. [. . . ] Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer. ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Customer Responsibilities section of this manual). 46 STORAGE CYLINDER(S) • • • • • Remove spark plug(s). [. . . ]
