Safety • Do not operate the machine while ill, tired, or under the This machine has been designed in accordance with ANSI standard B71.1-2012. • • To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means Caution, Warning, or Danger—personal safety instruction. Failure to comply with the instruction may result in personal injury or death.
Children Safe Handling of Gasoline Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them. To avoid personal injury or property damage, use extra care when handling gasoline and other fuels. They are flammable and the vapors are explosive.
General Service • If loading the machine onto a trailer or truck, use a single, full-width ramp only. The ramp angle should not exceed 15 degrees. • Never operate a machine inside a closed area. Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. • Removing standard original equipment parts and accessories may alter the warranty, traction, and safety of the machine. Failure to use original Toro parts could cause serious injury or death.

Ignition Switch Fuel-Presence Window The ignition switch has 3 positions: OFF, RUN, and START. The key will turn to START and move back to RUN upon release. Turning the key to the OFF position will shut off the engine; however, always remove the key when leaving the machine to prevent someone from accidentally starting the engine (Figure 6). he fuel window located on the left-hand side of the machine, can be used to verify the presence of gasoline in the tank (Figure 7).
Operation DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
Think Safety First of varnish deposits in the fuel system, use fuel stabilizer at all times. Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. Filling the Fuel Tank Note: Ensure that the engine is shut off and the motion controls are in the parked position. DANGER Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 8).
Testing the Safety-Interlock System 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. Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. Wear hearing protection when operating this machine. 1.
Starting the Engine Operating the Blades 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. 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.
Driving the Machine Driving Forward Driving the machine benefits from an understanding of what zero-turn-radius mower means. The drive wheels turn independently, powered by hydraulic motors on each axle; hence 1 side can turn in reverse while the other turns forward, causing the machine to spin rather than turn. This vastly improves the machine maneuverability but may require some adjustment if you are unfamiliar. Note: Always use caution when backing up and turning. 1.
Driving Backward To change speeds, do the following: 1. Move the motion-control levers to the NEUTRAL position and outward to the PARK position. Note: Always use caution when backing up and turning. 1. Move the levers to the center, unlocked position. 2. Disengage the blade-control switch. 2. To go backward, look behind you and down, as you slowly pull the motion-control levers rearward (Figure 16). 3. Adjust the lever to the desired position. The following are only recommendations for use.
Stopping the Machine Positioning the Seat To stop the machine, move the motion-control levers to the NEUTRAL position and outward to the PARK position, disengage the blade-control switch, ensure the throttle is between half and full throttle, and turn the ignition key to off. Remove the key from the ignition switch. Move the seat forward or backward as shown in Figure 19. A B WARNING Children or bystanders may be injured if they move or attempt to operate the mower while it is unattended.
Adjusting the Tilt 3 You can adjust the motion-control levers forward or rearward for your comfort. 1. Loosen the upper bolt holding the control lever to the control-arm shaft. 2. Loosen the lower bolt just enough to pivot the control lever forward or rearward (Figure 20). 3. Tighten both bolts to secure the control lever in the new position. 4. Repeat the adjustment for the other control lever. Pushing the Machine by Hand 1 2 g017303 Figure 21 Important: Always push the machine by hand.
Adjusting the Anti-Scalp Rollers WARNING Driving on the street or roadway without turn signals, lights, reflective markings, or a slow-moving-vehicle emblem is dangerous and can lead to accidents, causing personal injury. For 107 cm (42-inch) Mower Decks Whenever you change the height of cut, it is recommended to adjust the height of the anti-scalp rollers. Do not drive the machine on a public street or roadway.
moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If loading on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. 1 WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. • Use extreme caution when operating a machine on a ramp.
Operating Tips cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. Using the Fast Throttle Setting Stopping 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 5 hours • Change the engine oil and filter.
