  5. Wipe up any fuel that may have spilled to prevent a fire hazard.

    Important: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Checking the Interlock System

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Check the safety interlock system.
  • Caution

    If safety interlock switches are disconnected or damaged the machine could operate unexpectedly and cause personal injury.

    • Do not tamper with the interlock switches.

    • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.

    The purpose of the interlock system is to prevent the engine from cranking or starting unless the traction pedal is in the NEUTRAL position. Also, the engine should shut off if the traction pedal is moved either forward or reverse without an operator in the seat.

    1. Position the machine in a wide-open area free of debris and bystanders. Shut off the engine.

    2. Sit on the seat and engage the parking brake.

    3. Press the traction pedal in forward and reverse while trying to start the engine.

      Note: If the engine cranks, there may be a malfunction in the interlock system. Repair it immediately.If the engine does not crank, the system is operating correctly.

    4. Stay seated on the seat, with the traction pedal in the NEUTRAL position and the parking brake engaged, and start the engine.

    5. Rise off the seat and slowly press the traction pedal.

      Note: The engine should shut off in 1 to 3 seconds. Correct the problem if the system does not operate properly.

    During Operation

    Note: Determine the left and right sides of the machine from the normal operating position.

    General Safety

    • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

    • Wear appropriate clothing, including eye protection; slip-resistant, substantial foot protection; long pants; and hearing protection. Tie back long hair and do not wear loose jewelry.

    • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

    • Never carry passengers on the machine and keep bystanders and pets away from the machine during operation.

    • Operate the machine only in good visibility to avoid holes or hidden hazards.

    • Avoid operating on wet grass. Reduced traction could cause the machine to slide.

    • Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.

    • Look behind and down before backing up to be sure of a clear path.

    • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

    • Do not operate near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge gives way.

    • Stop the machine and inspect the attachment after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

    • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Never run an engine in an area where exhaust gasses are enclosed.

    • Never leave a running machine unattended.

    • Before leaving the operating position, do the following:

      • Park the machine a level surface.

      • Lower the attachments.

      • Engage the parking brake.

      • Shut off the engine and remove the key.

      • Wait for all moving parts to stop.

    • Do not operate the machine when there is the risk of lightning.

    • Do not use the machine as a towing vehicle.

    • When necessary, wet surfaces prior to conditioning to minimize dust creation.

    • Use accessories, attachments, and replacement parts approved by Toro only.

    Slope Safety

    • Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.

    • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution.

    • Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope requires extra caution.

    • Operate the machine at a lower speed when you are on a slope.

    • If you feel uneasy operating the machine on a slope, do not do it.

    • Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

    • Choose a low ground speed so you will not have to stop or shift while on a slope.

    • A rollover can occur before the tires lose traction.

    • Avoid operating the machine on wet grass. Tires may lose traction; regardless if the brakes are available and functioning.

    • Avoid starting, stopping, or turning the machine on a slope.

    • Keep all movement on slopes slow and gradual. Do not suddenly change the speed or direction of the machine.

    • Do not operate the machine near drop-offs, ditches, embankments, or bodies of water. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard (2 machine widths).

    Starting and Shutting Off the Engine

    1. Remove your foot from the traction pedal, ensure that the pedal is in the NEUTRAL position, and engage the parking brake.

    2. Push the choke lever forward to the ON position (when starting a cold engine) and the throttle lever to the SLOW position.

      Important: When operating the machine in temperatures less than 0°C (32°F) allow the machine time to warm up before using it. This prevents damage to the hydrostat and the traction loop.

    3. Insert the key into the ignition switch and rotate it clockwise to start the engine. Release the key when the engine starts.

      Note: Regulate the choke to keep the engine running smoothly.

      Important: To prevent overheating the starter motor, do not engage the starter longer than 10 seconds. After 10 seconds of continuous cranking, wait 60 seconds before engaging the starter motor again.

    4. To shut off the engine, move the throttle control to the SLOW position and rotate the ignition key to OFF.

      Note: Remove the key from the switch to prevent accidental starting.

    5. Close the fuel-shutoff valve before storing the machine.

      Caution

      Inspecting the machine while the engine is running could result in injury.

      Shut the engine off and wait for all moving parts to stop before checking for oil leaks, loose parts, and other malfunctions.

    Breaking in the Machine

    New engines take time to develop full power. Drive systems have more friction when they are new, placing additional load on the engine.

    Allow the first 8 hours of operating time for the break-in period.

    Since the first hours of operation are critical to future dependability of the machine, monitor the functions and performance closely so that you can notice and correct minor difficulties, which could lead to major problems. Inspect the machine frequently during the break-in period, for signs of oil leakage, loose fasteners, or any other malfunction.

    Becoming Familiar with the Machine

    Refer to the attachment Operator's Manual for specific operating instructions for the attachment.

    Practice driving the machine, because its operating characteristics are different than some utility vehicles. 2 points to consider when operating the vehicle are transmission speed and engine speed.

    To maintain constant engine speed, press the traction pedal slowly. This allows the engine to keep up with the ground speed of the vehicle. By contrast, pushing down quickly on the traction pedal reduces the engine speed; as a result, there will not be enough torque-power to move the vehicle. Therefore, to transfer maximum power to the wheels, move the throttle to FAST and slightly press the traction pedal. By comparison, maximum ground speed with no load results when the throttle is in the FAST position and the traction pedal is slowly but fully pressed. Always keep the engine speed high enough to deliver maximum torque-power to the wheels.

    Caution

    Operating the machine demands attention to prevent tipping or loss of control.

    • Use care when entering and leaving sand traps.

    • Use extreme caution around ditches, creeks, or other hazards.

    • Use caution when operating the machine on a steep slope.

    • Reduce your speed when making sharp turns or when turning on hillsides.

    • Avoid sudden stops and starts.

    • Do not go from reverse to full forward without first coming to a complete stop.

    Note: If the attachment adapter becomes stuck to the traction unit adapter, insert a pry bar or a screwdriver into the pry slot to disengage the parts (Figure 17).

    g003783

    After Operation

    After Operation Safety

    • Park the machine on a level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine.

    • Clean grass and debris from the muffler and engine compartment to help prevent fires. Clean up oil or fuel spills.

    • Allow the engine to cool before storing the machine in any enclosure.

    • Shut off the fuel before storing or transporting the machine.

    • Never store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.

    • Keep all parts of the machine in good working condition and all hardware tightened.

    • Replace all worn, damaged, or missing decals.

    Towing the Machine

    In case of emergency, you can tow the machine for a short distance. However, we do not recommend this as a standard procedure.

    Important: Do not tow the machine faster than 1.6 km/h (1 mph), because drive system damage may occur. If you must move the machine more than 50 m (55 yd), transport it on a truck or a trailer. The tires may lock up if you tow the machine too fast. If this occurs, stop towing the machine and wait for the traction circuit pressure to stabilize before resuming towing at a slower speed.

    Hauling the Machine

    • Use full-width ramps for loading the machine onto a trailer or truck.

    • Tie the machine down securely.

    Preparing the Machine

    1. Thoroughly clean the machine, the attachments, and the engine.

    2. Park the machine on a level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine.

    3. Check the tire pressure; refer to Checking the Tire Pressure.

    4. Check all fasteners for looseness; tighten as necessary.

    5. Grease or oil all grease fittings and pivot points; refer to Greasing the Machine.

    6. Lightly sand and use touch-up paint on painted areas that are scratched, chipped, or rusted.

    Preparing the Engine

    1. Change the engine oil and filter; refer to Changing the Engine Oil and Filter.

    2. Start the engine and run it at idle speed for 2 minutes.

    3. Shut off the engine; remove the key; and wait for all movement to stop before leaving the machine.

    4. Thoroughly clean and service the air-cleaner assembly; refer to Servicing the Air Cleaner.

    5. Seal the air-cleaner inlet and the exhaust outlet with weatherproof masking tape.

    6. Check the oil-filler cap and the fuel-tank cap to ensure that they are securely in place.

    Preparing the Battery

    1. Remove the battery terminals from the battery posts.

    2. Clean the battery, terminals, and posts with a wire brush and a baking-soda solution.

    3. Coat the cable terminals and battery posts with Grafo 112X skin-over grease (Toro Part 505-47) to prevent corrosion.

    4. Slowly charge the battery for 24 hours every 60 days to prevent lead sulfation of the battery.

      Note: The specific gravity of a fully charged battery measures 1.250.

    Note: Store the battery in a cool atmosphere to avoid quick deterioration of the charge in the battery. To prevent the battery from freezing, make sure that it is fully charged.
