CONTROLS Technical Data concerning ethanol fuel. Methanol fuel is not allowed. Do not use E85 alcohol based fuel. Damage to the engine and components may occur. When operating in temperatures below (32°F) 0°C, use fresh, clean winter grade gasoline to help insure good cold weather starting. IMPORTANT INFORMATION Experience indicates that alcohol blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system must be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage for more information. Do not use engine or carburetor cleaners in the fuel tank or permanent damage may occur. 2. For preliminary tracking adjustment, move unit to an open, unobstructed area such as an empty parking lot or open field. 3. Back the bolts out until flush with nut. 4. Test operate unit by driving it at full throttle and the full forward position on the two steering control levers. Gradually turn in the tracking bolt on the right hand side until the unit noticeably starts drifting right. 5. Drive forward at full throttle with the two steering control levers in the full forward position. Gradually turn in the left hand tracking bolt until unit tracks straight. WARNING! Gasoline is highly flammable. Observe caution and fill the tank outdoors (see the safety section). WARNING! The engine and the exhaust system, become very hot during operation. There is a risk for burns if touched. Let engine and exhaust system to cool before refueling. Tracking If the mower is not tracking straight, check the air pressure in the two rear tires. Recommended air pressure for the rear tires is 15 psi (1 bar). 1. Tracking adjustments are made using the tracking bolts. The bolts act as limiting devices for the motion control levers when in the fullforward position. 16
