The fuel gauge monitors the amount of fuel in the left tank only. Use the fuel from the right fuel tank first. When the right fuel tank is empty switch to the left fuel tank. Fuel gauge will monitor the remaining fuel. 4.1.12 Drive Wheel Release Valves: Located on the top right front corner of hydrostatic pumps. Drive wheel release valves are used to release the hydrostatic drive system to allow the machine to be pushed without the engine running. Unhook seat latch and tilt seat up to gain access to pumps. With a 5/8 wrench, turn both valves one turn counter-clockwise to release drive system. Turn clockwise to reset system. DO NOT overtighten. DO NOT tow machine. 4.2 PRE-START 4.2.1 Fill fuel tanks. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline may also be used; however, combustion chamber and cylinder head will require more frequent service. See Engine Owner's Manual. DO NOT add oil to gasoline. DO NOT overfill fuel tank. Never fill the fuel tank so that the fuel level rises above a level that is 1/2” below the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage. 4.2.2 Make sure you understand the controls, their locations, their functions, and their safety requirements. 4.2.3 Refer to Maintenance, Section 5, and perform all the necessary inspection and maintenance steps. 4.3 OPERATING INSTRUCTIONS 4.3.1 Operate units with the roll bar in the raised and locked position and use seat belt. There is no rollover protection when the roll bar is down. If it is necessary to lower roll bar do not wear the seat belt. Raise the roll bar as soon as clearance permits. 4.3.2 Open fuel shut-off valve (left or right tank). 4.3.3 Starting Engine: Brake must be engaged, motion control levers out (neutral lock position) and PTO switch “OFF” to start engine. (It is not necessary for the operator to be in the seat to start the engine.) - 20 On a cold engine, place the throttle midway between the “SLOW” and “FAST” positions and push choke lever forward into the “ON” position. Turn ignition switch to the “start” position. Release the switch as soon as the engine starts. IMPORTANT: DO NOT crank the engine continuously for more then ten (10) seconds at a time. If the engine does not start, allow a 60 second cool- down period between starting attempts. Failure to follow these guidelines can burn out the starter motor. After starting a cold engine, gradually return choke to the “OFF” position as the engine warms up. On a warm engine, place the throttle midway between the “SLOW” and “FAST” positions and leave the choke in the “OFF” position. 4.3.4 Engaging PTO: DANGER POTENTIAL HAZARD ¦ The rotating blades under the mower deck are dangerous. WHAT CAN HAPPEN ¦ Blade contact can cause serious injury or kill you. HOW TO AVOID THE HAZARD ¦ DO NOT put hands or feet under the mower or mower deck when the blades are engaged. DANGER POTENTIAL HAZARD ¦ An uncovered discharge opening will allow objects to be thrown in an operator’s or bystander’s direction. Also, contact with the blade could occur. WHAT CAN HAPPEN ¦ Thrown objects or blade contact can cause serious injury or death. HOW TO AVOID THE HAZARD ¦ Never operate the mower with the discharge deflector raised, removed, or altered unless there is a grass collection system or mulch kit in place and working properly. The PTO push-pull switch engages the cutting blades. Be sure that all persons are clear of the mower deck and discharge area before engaging PTO. IMPORTANT: Operator must be in seat before the PTO can be engaged. Set throttle to "midway" position. Pull outward on the switch to the “ROTATE” position. Accelerate to full throttle to begin mowing. 4.3.5 Stopping PTO: Set throttle to the “midway” position. Push in on the switch to the “STOP” position stopping the PTO. 4.3.6 Stopping Engine: Bring unit to a full stop. Disengage the PTO, move motion control levers out to the neutral lock position and set parking brake. Before stopping the engine, place the throttle control midway between the “slow” and “fast” positions. Allow the engine to run a minimum of 15 seconds; then stop the engine. - 21 Rotate ignition switch to “OFF” position. Remove the key to prevent children or other unauthorized persons from starting engine. Close fuel shut-off valve when machine will not be used for a few days, when transporting, and when the unit is parked inside a building. 4.4 TRANSPORTING 4.4.1 Transporting a Unit: Use a heavy-duty trailer or truck to transport the machine. Lock brake and block wheels. Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. Be sure that the trailer or truck has all necessary lighting and marking as required by law. Secure a trailer with a safety chain. CAUTION POTENTIAL HAZARD ¦ This unit does not have proper turn signals, lights, reflective markings, or a slow moving vehicle emblem. These items are required to ...
