Ignition Switch Product Overview The ignition switch has 3 positions: OFF, RUN, and START. The key turns to START and moves back to RUN upon release. Turning the key to the OFF position stops the engine; however, always remove the key when leaving the machine to prevent someone from accidentally starting the engine (Figure 5). Throttle Control The throttle controls the engine speed and it has a continuous variable setting from the SLOW to FAST position (Figure 5).
Operation G014521 Note: Determine the left and right sides of the machine from the normal operating position. Adding Fuel • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • Ethanol: Gasoline with up to 10% ethanol (gasohol) 1 or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. DANGER In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.
Think Safety First CAUTION This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. Wear hearing protection when operating this machine. DANGER Operating the machine on wet grass or steep slopes can cause sliding and loss of control.
Testing the Safety-Interlock System Starting the Engine Note: A warm or hot engine may not require choking. Important: Do not engage the starter for more than 5 seconds at a time. Engaging the starter motor for more than 5 seconds can damage the starter motor. If the engine fails to start, wait 10 seconds before operating the engine starter again. Test the safety-interlock system before you use the machine each time.
Operating the Blades 2. Move the throttle lever to the SLOW position. Note: Run it at idle speed for approximately one minute. The blade-control switch engages and disengages power to the mower blades. This switch controls power to any attachments that draw power from the engine, including the mower deck and cutting blades. 3. Turn the ignition key to the OFF position and remove the key.

Using the Grass Deflector Transporting the Machine The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.
Loading the Machine 1 Use extreme caution when loading or unloading the machine onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back the machine up the ramp and drive it forward down the ramp (Figure 24). Figure 24 1. Back the machine up the ramp. 2 2. Drive the machine forward down the ramp. Important: Do not use narrow individual ramps for each side of the machine.
Keeping the Underside of the Mower Clean Operating Tips Using the Fast Throttle Setting Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory. For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower in uncut grass.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Change the engine oil.

A • Perform any fuel-related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. B • Never smoke when draining gasoline and stay away from an open flame or where a spark may ignite the gasoline fumes.
Electrical System Maintenance WARNING Incorrect battery-cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. WARNING • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. CALIFORNIA Proposition 65 Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm.
Charging the Battery Servicing the Fuses Service Interval: Before storage—Charge the battery and disconnect the battery cables. The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component or circuit for a malfunction or short. 1. Remove the battery from the chassis; refer to Removing the Battery (page 35). Fuse type: 2. Charge the battery for a minimum of 1 hour at 6 to 10 A.
Releasing the Electric Brake Drive System Maintenance The electric brake releases by manually rotating the link arms forward. Once the electric brake is energized, the brake resets. Checking the Tire Pressure Service Interval: Every 25 hours—Check tire pressure. Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause an uneven cut. Check the pressure at the valve stem (Figure 41). Check the tires when they are cold to get the most accurate pressure reading.
Mower Maintenance Servicing the Cutting Blades Maintain sharp blades throughout the cutting season, because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding the grass turns it brown at the edges, which slows growth and increases the chance of disease. Figure 43 Check the cutting blades daily for sharpness and for any wear or damage. File down any nicks and sharpen the blades as necessary.
3. Measure from the tip of the blade to the flat surface (Figure 45). 1 1 G014973 3 2 G014973 3 Figure 47 2 1. Opposite blade edge (in position for measuring) Figure 45 2. Level surface 3.
