Adjust the raise and lower delay time for the center cutting with the InfoCenter, as desired from 1 to 10 according to the table below. The factory default setting is 6 (375 ms) and is optimized for a 3.8 mph mow speed.

The tap-off delay feature allows the cutting units to turn off without raising, and you may adjust it with the InfoCenter. The delay setting represents the maximum time for the raise/lower joystick to remain in the raise position to activate this feature. The factory default setting is 1 which disables this feature.

To achieve a consistent, high quality-of-cut and a uniform after cut appearance, the machine has a clip-control feature that varies the speed of the reels with the speed of the machine, to maintain a constant clip. This feature is OFF by default; configure it and turn it ON as follows:

1. From the SETTINGS menu, select CLIP CONTROL.

2. Set CLIP CONTROL to ON.

3. From the SETTINGS menu, select BLADE COUNT.

4. Set the BLADE COUNT to match the number of blades in each of your reels.

5. From the SETTINGS menu, select CLIP (FOC)

6. Set CLIP (FOC) to the desired clip setting.

The clip-control feature automatically sets the reel speed to match the machine speed. If you choose not to use the clip-control feature, set the reel speed manually as follows:

1. Select the height-of-cut at which the cutting units are set.

2. Choose the desired ground speed best suited for conditions.

3. Using the appropriate graph (Figure 17) for 5-, 8-, 11-, or 14-blade cutting units, determine the proper reel speed setting.

   

   Figure 18

4. To set the reel speed, on the InfoCenter open the Main Menu and scroll down to SETTINGS.

5. In the SETTINGS menu, scroll down to REEL SPEED and use the ± button to set the reel speed to the desired number.

You can set a passcode on the InfoCenter so that operator’s cannot change the following machine settings without it: RAISE DELAY, LOWER DELAY, TAP-OFF DELAY, REEL SPEED, BACKLAP SPEED, CLIP CONTROL, BLADE COUNT, and CLIP (FOC).

1. From the SETTINGS menu, select PROTECT SETTINGS.

2. Set PROTECT SETTINGS to ON.

3. When prompted, enter a 4-digit passcode.

4. Turn the ignition key to OFF to save the code.

Note: If you forget the user defined passcode, you can obtain a temporary passcode from your authorized Toro distributor.

The fault-log indicator icon appears on the main screen in the event of a fault in the machine. When this icon is present there is a new log entry in the Faults menu that you or your authorized Toro distributor can use to identify the problem.

For a list of faults, refer to your authorized Toro distributor or the Service Manual.

Fuel tank capacity: 26.6 L (7 US gallons)

Recommended Fuel: 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.

• Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol).

• Do not use fuel that contains methanol.

• Do not store fuel either in the fuel tank or fuel containers over the winter, unless you use a fuel stabilizer.

• Do not add oil to gasoline.

• For best results, use only clean, fresh (less than 30 days old) fuel.

• Using unapproved gasoline may cause performance problems and/or engine damage, which may not be covered under the warranty.

Important: Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.

   2. Fuel-tank cap

2. Add the specified fuel to the fuel tank until the level is 25 mm (1 inch) below the bottom of the filler neck.

   This space in the tank allows the fuel to expand. Watch the fuel level in the sight gauge or fuel gauge when you are filling the tank.

   Important: Do not fill the fuel tank completely full.

3. Install the cap.

   Note: You will hear a click sound when the cap is secure.

4. Wipe up any spilled fuel.

Before starting the machine each day, perform the following procedures:

• Check the engine-oil level—refer to Checking the Engine Oil.

• Check the hydraulic-fluid level—refer to Checking the Hydraulic-Fluid Level.

• Check the reel-to-bedknife contact—refer to Checking the Reel-to-Bedknife Contact.

• Check the tire pressure—refer to Checking the Tire Pressure.

Refer to the engine Owner’s Manual supplied with the machine for oil change and maintenance procedures recommended during the break-in period.

Only 8 hours of operation is required for the break-in period.

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

Note: Inspect the areas beneath the cutting units to ensure that they are clear of debris.

1. Sit on the seat, engage the parking brake, disengage the raise/lower mow control and move the functional-control lever to the NEUTRAL position.

2. Ensure that the traction pedal is in the NEUTRAL position and that you foot is off the pedal.

3. If you are starting a cold engine, move the choke to the ON position.

4. Move the throttle lever to the HALF THROTTLE position.

5. Insert and rotate the ignition key clockwise until the engine starts.

6. After the engine starts, adjust the choke to run the engine smoothly. As soon as possible, open the choke by pulling it rearward to the OFF position. A warm engine requires little or no choking.

1. Move the throttle lever to the FAST position.

2. Move the raise/lower mow control lever forward momentarily.

   The cutting units should lower and all the reels should rotate.

   Note: The function lever should be in the middle (mow) position for the reels run when lowering the cutting units

3. Move the raise/lower mow control lever rearward.

   The cutting reels should stop rotating and the cutting units should raise to the full transport position.

4. Engage the brake to keep the machine from moving, and operate the traction pedal through the forward and reverse positions.

5. Continue the above procedure for 1 or 2 minutes. Move the functional-control lever to the NEUTRAL position, engage the parking brake, and shut off the engine.

6. Check for fluid leaks and tighten the hydraulic fittings if any leaks are found.

   Note: When the machine is new and the bearings and reels are tight, it is necessary to use the FAST throttle-lever position for this check. A fast throttle setting may not be required after the break-in period.

   Note: If fluid leaks continue to appear, contact your authorized Toro distributor for assistance and, if necessary, replacement parts.

   Important: A trace of fluid on the motor or wheel seals is normal. Seals require a small amount of lubrication to perform properly.

1. Move the throttle lever to the SLOW position, pull back the raise/lower mow control, and move the functional-control lever to the NEUTRAL position.

2. Rotate the ignition key to the OFF position to shut off the engine. Remove the key from the switch to prevent accidental starting.

3. Close the fuel shut-off valve before storing the machine.

The purpose of the safety-interlock system is to prevent operation of the machine where there is possible injury to you or damage to the machine.

The safety-interlock system prevents the engine from starting unless:

• The traction pedal is in the NEUTRAL position.

• The functional-control lever is in the NEUTRAL position.

The safety-interlock system prevents the machine from moving unless:

• The parking brake is disengaged.

• You are seated in the operator's seat.

• The functional-control lever is in the MOW position or the TRANSPORT position.

The safety-interlock system prevents the reels from operating unless the functional-control lever is in the MOW position.

• Ensure that the cutting units are fully raised.

• Move the functional-control lever to the TRANSPORT position.

• Use the brakes to slow the machine while going down steep hills to avoid loss of control.

• Always approach rough areas at a reduced speed and cross severe undulations carefully.

• Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together to prevent costly damage and downtime.

Important: If the leak detector alarm (if equipped on your model) sounds or you notice an oil leak while cutting on a green, immediately raise the cutting units, drive directly off the green, and stop the machine in an area away from the green. Determine the cause of the leak and correct the problem.

Before mowing greens, find a clear area and practice performing basic machine functions (e.g., starting and stopping the machine, raising and lowering the cutting units, and turning).

Inspect the green for debris, remove the flag from the cup, and determine the best direction to mow. Base the direction to mow on the previous mowing direction. Always mow in an alternate pattern from the previous mowing so that the grass blades are less apt to lay down and therefore be difficult to trap between the reel blades and the bedknife.

After mowing, thoroughly wash the machine with a garden hose without a nozzle so that excessive water pressure does not contaminate and damage the seals and bearings. Do not wash a warm engine or the electrical connections with water.

After cleaning the machine, do the following:

• Inspect the machine for possible hydraulic fluid leaks, damage or wear to hydraulic and mechanical components.

• Inspect the cutting units for sharpness.

• Lubricate the brake-shaft assembly with SAE 30 oil or spray lubricant to deter corrosion and help keep the machine performing satisfactorily during the next mowing operation.

• Use care when loading or unloading the machine into a trailer or a truck.

• Use a full-width ramp for loading the machine into a trailer or a truck.

• Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine.

In case of an emergency, you can tow the machine for up to 0.4 km (1/4 mile).

Important: Do not tow the machine faster than 3 to 5 km/h (2 to 3 mph) to avoid damaging the drive system. If you must move the machine more than 0.4 km (1/4 mile), transport it on a truck or trailer.

1. Locate the bypass valve on the pump and rotate it so that the slot is vertical (Figure 26).

   

   Figure 26

   1. Bypass valve-slot shown in closed (horizontal) position

2. Before starting the engine, close the bypass valve by rotating it so that the slot is horizontal (Figure 26).

   Important: Do not start the engine when the bypass valve is open.

Lubricate the grease fitting with No. 2 lithium grease.

1. Wipe the grease fitting clean so that you do not force foreign matter into the bearing or bushing (Figure 27).

   

   Figure 27

   Left side of the gasoline model shown; your model may vary

2. Pump grease into the bearing or bushing until the grease is visible. Wipe up excess grease.

• Shut off the engine before checking the oil or adding oil to the crankcase.

• Do not change the governor speed or overspeed the engine.

1. Clean the air-cleaner cover (Figure 28).

   

   Figure 28

   1. Air-cleaner cover

2. Release the locking clips and remove the air-cleaner cover.

3. Remove the wing nut securing the elements to the air-cleaner body (Figure 29).

4. If the foam element is dirty, remove it from the paper element (Figure 29). Clean it thoroughly, as follows:

   1. Wash the foam element in a solution of liquid soap and warm water. Squeeze it to remove dirt.

   2. Dry it by wrapping it in a clean rag. Squeeze the rag and foam element dry.

      Important: When drying the foam element, do not twist it; the foam may tear.

      1. Foam element
      2. Paper element

5. Check the condition of the paper element. Clean it by gently tapping it on a flat surface or replace it if needed.

6. Install the foam element, paper element, wing nut, and air-cleaner cover.

   Important: Do not operate the engine without the air-cleaner element because extreme engine wear and damage will likely result.

The engine is shipped with oil in the crankcase; however, you must check the oil level before and after starting the engine the first time.

Spark plug specification: Champion RC 14YC

Air gap specification: 0.76 mm (0.030 inch)

1. Clean the area around the spark plugs so that foreign matter cannot fall into the cylinder.

2. Pull the wires off the spark plugs and remove the plugs.

3. Check the condition of the side electrode, center electrode, and center electrode insulator to ensure that there is no damage.

   Important: Replace a cracked, fouled, dirty, or otherwise malfunctioning spark plug. Do not sand blast, scrape, or clean electrodes by using a wire brush because grit may eventually release from the plug, fall into the cylinder, and damage the engine.

4. Set the air gap between the center and side of the electrodes at 0.76 mm (0.030 inch) as shown in Figure 32.

   

   Figure 32

5. Install the spark plug and gasket seal, and torque the plug to 23 N∙m (200 in-lb).

3. Loosen the other hose clamp and remove the filter (Figure 33).

4. Install the new filter with the arrow on the filter body pointing away from the fuel tank.

Inspect the fuel lines for deterioration, damage, or loose connections.

Properly maintain the battery electrolyte and keep the top of the battery clean. Store the machine in a cool place to prevent the battery from running down.

The battery cables must be tight on the terminals to provide good electrical contact.

1. Check the electrolyte level in the in the cells of the battery.

2. If needed, add distilled or demineralized water into the cell of the battery.

   Note: Raise the electrolyte level only to the bottom of the split ring inside each cell.

3. Clean the top of the battery by washing it periodically with a brush dipped in ammonia or bicarbonate of soda solution.

4. Flush the top surface of the battery with water after cleaning it.

   Important: Do not remove the fill caps while cleaning the battery.

If corrosion occurs at the terminals, disconnect the cables, negative (-) cable first, and scrape the clamps and terminals separately. Connect the cables, positive (+) cable first, and coat the terminals with petroleum jelly.

3. Rotate the trunnion bolt clockwise to reduce the mowing speed and counterclockwise to increase the mowing speed.

4. Tighten the jam nut on the trunnion bolt and the nut on the pedal pivot to lock the adjustment (Figure 39). Check the adjustment and adjust as required.

If the brake fails to hold the machine while parked, you can adjust the brakes using the bulkhead fitting near the brake drum; contact your Authorized Service Dealer or refer to the Service Manual for more information.

Note: Burnish the brakes annually; refer to Burnishing the Brakes.

Important: Regardless of the hydraulic fluid type used, any traction unit used for off-green applications, verticutting or used during ambient temperatures above 29° C (85°F) should have the Oil Cooler Kit installed; refer to Installing the Oil Cooler.

Check the hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating the machine.

The leak detector system is designed to assist in early detection of hydraulic-fluid-system leaks. If the fluid level in the main hydraulic reservoir is lowered by 118 to 177 ml (4 to 6 oz), the float switch in the tank will close. After a 1 second delay, the alarm sounds, alerting the operator (Figure 45). Expansion of fluid, due to normal heating during machine operation, causes the fluid to transfer into the auxiliary fluid reservoir. The fluid returns to the main tank when you turn off the ignition switch.
