Preparation Safety • While mowing, always wear substantial footwear, long trousers, hard hat, safety glasses, and hearing protection. Long hair, loose clothing, or jewelry may get tangled in moving parts. Do not operate the equipment when barefoot or wearing open sandals. This machine meets or exceeds CEN standard EN 836:1997 (when appropriate decals applied), and ANSI B71.4-2004 specifications in effect at the time of production.
• • • • • • • • • • • • • • • • • Lightning can cause severe injury or death. If lightning – Stay alert for humps and hollows and other hidden hazards. – Never mow across the face of the slope, unless the mower is designed for this purpose. Stay alert for holes in the terrain and other hidden hazards. Watch out for traffic when crossing or near roadways. Stop the blades from rotating before crossing surfaces other than grass.
• Do not operate on a side hill that is too steep. A rollover Use of this product for purposes other than its intended use could prove dangerous to user and bystanders. may occur before losing traction. • The slope angle at which the machines will tip is WARNING dependent on many factors. Among these are mowing conditions such as wet or undulating terrain, speed (especially in turns), position of the cutting units (up or down), tire pressure, and operator experience.
• If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing, and any parts of the body away from the cutting units, attachments, and any moving parts. Keep everyone away. • Do not overspeed the engine by changing governor settings. To ensure safety and accuracy, have an Authorized Toro Distributor check the maximum engine speed with a tachometer. • The engine must be shut off before checking the oil or adding oil to the crankcase.

Tilt Steering Lever Product Overview Pull the tilt steering lever (Figure 18) back to tilt the steering wheel to the desired position. Then push the lever forward to tighten. Controls Ignition Switch The ignition switch (Figure 20), used to start, stop, and preheat the engine, has three positions: Off, On/Preheat, and Start.
Lower Mow/Raise Control Lever This lever (Figure 20) raises and lowers the cutting units and also starts and stops the cutterheads when the cutterheads are enabled in the mow mode. The cutting units cannot be lowered when the mow/transport lever is in the transport position. Note: When the cutting units re enabled, the lever does not have to be held in the forward position while the cutting units are lowered or raised. Figure 21 1.
Operation Note: Determine the left and right sides of the machine from the normal operating position. Checking the Engine Oil Level Service Interval: Before each use or daily The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started. Crankcase capacity is approximately 4 qt (2.8 l) with the filter. Use high-quality engine oil that meets the following specifications: • API Classification Level Required: CH-4, CI-4 or higher.
2. Remove the fuel tank cap. 3. Fill the tank to the bottom of the filler neck. Do not overfill. Install the cap. 4. To prevent a fire hazard, wipe up any fuel that may have spilled. Figure 25 1. Oil fill cap 5. Install the oil fill cap and close the hood. Figure 26 Filling the Fuel Tank 1. Fuel tank cap Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40.
Checking the Cooling System Service Interval: Before each use or daily Clean debris off of the radiator/oil cooler daily (Figure 27). Clean the radiator/oil cooler hourly if conditions are extremely dusty and dirty; refer to Cleaning the Engine Cooling System. Figure 28 1. Expansion tank Checking the Hydraulic System Service Interval: Before each use or daily—Check the hydraulic fluid level. Figure 27 The machines reservoir is filled at the factory with approximately 13.2 liters (3.5 U.S.
Checking the Tire Pressure Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H Service Interval: Before each use or daily Important: Mobil EAL EnviroSyn 46H is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions.
Changing the Arm Rest Position Starting and Stopping the Engine The armrests of the seat can be adjusted to provide a comfortable ride. Position the armrests where they are most comfortable. You may need to bleed the fuel system if any of the following situations have occurred (refer to Bleeding the Fuel System): To adjust, raise the arm rest and turn the knob, in either direction, to provide the best comfort (Figure 30).
Setting the Reel Speed 2. Choose the desired ground speed best suited for conditions. To achieve a consistent, high quality-of-cut and a uniform after cut appearance, it is important that you set the reel speed controls (located under the seat) correctly. Adjust the reel speed controls as follows: 1. Select the height-of-cut at which the cutting units are set. 3. Use the graph, on reel speed chart decal (Figure 31), to determine the proper reel speed setting. Figure 31 1. 8 blade reel adjustment 3.
CAUTION DANGER The springs are under tension. Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. Use caution when adjusting them. 3. While relieving the spring tension, remove the bolt and locknut securing the spring actuator to the bracket (Figure 33). • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold.
Understanding the Diagnostic Light what function is required for various input switches (i.e. seat switch, key switch, etc.) and turns on the outputs to actuate solenoids or relays for the requested machine function. The machine is equipped with a diagnostic light which indicates if the electronic controller senses an electronic malfunction. The diagnostic light is located on the control panel (Figure 35).
and note that the appropriate LED on Diagnostic ACE will blink on and off when corresponding switch is closed. Repeat this for all switches that you can change by hand. 9. If a switch is closed and the appropriate LED does not turn on, check all wiring and connections to the switch and/or check the switches with an ohm meter. Replace any defective switches and repair any defective wiring. Note: The Diagnostic ACE also has the ability to detect which output solenoids or relays are turned on.
correctly illuminated, this indicates an ECM problem. If this occurs, contact your Toro Distributor for assistance DANGER When operating the machine, always use the seat belt and ROPS together. Do not use a seat belt without a ROPS. Important: The Diagnostic ACE display must not be left connected to the machine. It is not designed to withstand the environment of the machine's every day use.
