Key Switch Fuel-Presence Window The key switch, used to start and shut off the engine, has 3 positions: OFF, RUN, and START . Refer to Starting the Engine (page 21). You can use the fuel window, located on the left side of the machine, to verify the presence of fuel in the tank (Figure 7). Throttle/Choke Control The throttle and choke controls are combined into 1 control lever. The throttle controls the engine speed and has a continuous-variable setting from SLOW to FAST (Figure 6).
Operation Pre-Start Note: Determine the left and right sides of the Fill fuel tank on level ground. See Fuel Recommendations in the Specifications section for additional gasoline information. machine from the normal operating position. Do Not add oil to gasoline. Before Operation Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.
Fuel Safety DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage. • Always place gasoline containers on the ground away from your vehicle before filling.
Adding Fuel Recommended 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) 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.
Understanding the Safety-Interlock System Positioning the Seat The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 9). The safety-interlock system is designed to prevent the engine from starting unless: • The blade-control switch (PTO) is disengaged. • The motion-control levers are in the PARK position.
Adjusting the Motion-Control Levers During Operation During Operation Safety Adjusting the Height General Safety You can adjust the motion-control levers higher or lower for maximum comfort (Figure 10). The operator must use their full attention when operating the machine. Do Not engage in any activity that causes distractions; otherwise, injury or property damage may occur. WARNING Operating engine parts, especially the muffler, become extremely hot.
• Be sure all drives are in neutral and parking brake • • • • is engaged before starting engine. Start the engine carefully according to instructions with feet well away from the blades. Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition. Keep clear of the discharge opening at all times.
Operating the Mower Blade-Control Switch (PTO) distance (twice the width of the machine) between the machine and any hazard. Use a walk behind machine or a hand trimmer to mow the grass in these areas. The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Engaging the Blade-Control Switch (PTO) g008945 Figure 12 g221745 Figure 11 Note: Always engage the blades with the throttle in 1.
Operating the Throttle Starting the Engine You can move the throttle control between FAST and SLOW positions (Figure 15). 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. Always use the FAST position when engaging the PTO.
4. Turn the key to the OFF position and remove the key. The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the full throttle position when mowing. CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. WARNING The machine can spin very rapidly.

Using the Side Discharge Adjusting the Height of Cut The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Note: The transport position is the highest height-of-cut position or cutting height at 115 mm (4-1/2 inches) as shown in Figure 21. Height of cut is controlled by the lever located to the right of the operating position (Figure 21).
Adjusting the Anti-Scalp Rollers Operating Tips Using the Fast Throttle Setting For Machine with 107 cm (42-inch) Mower Decks Only 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 deck in uncut grass. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.
After Operation drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward. After Operation Safety Keeping the Underside of the Mower Deck Clean General Safety • Park machine on level ground, disengage drives, Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, cutting quality will eventually become unsatisfactory.
