The machine has grease fittings that you must lubricate regularly with No. 2 lithium grease. Lubricate the grease fittings immediately after every washing, regardless of interval specified.

1. Wipe the grease fittings clean so that foreign matter cannot be forced into the bearing or bushing (Figure 28).

2. Pump the grease into the fittings.

3. Wipe off any excess grease.

Figure 28

Shown with cutting unit installed

Note: To access the grease fittings for the rear-steering linkage, remove the storage compartment.

Note: Raise the machine off the floor with a jack and secure it with jack stands to allow better grease migration through both the upper and lower king-pin bushings. You should see grease purging out of both the top and the bottom of the axle casting/bushing assembly areas of all 4 kingpin assemblies (Figure 29).

Figure 29

Note: The bearing life can be negatively affected by improper washing procedures. Do not wash the machine when it is still hot and avoid directing high-pressure or high-volume spray at the bearings or seals.

Check the air-cleaner body for damage that could cause an air leak. Replace a damaged air cleaner. Check the whole intake system for leaks, damage, or loose hose clamps.

Service the air-cleaner filter only when the service indicator (Figure 30) requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when you remove the filter.

Important: Be sure that the cover is seated correctly and seals with the air-cleaner body.

1. Release the latch securing the air-cleaner cover to the air-cleaner body (Figure 30).

   

   Figure 30

   1. Air-cleaner-service indicator
   2. Air-cleaner cover
   3. Air-cleaner-cover latch

2. Remove the cover from the air-cleaner body. Before removing the filter, use clear and dry low-pressure air (276 kPa or 40 psi) to help remove large accumulations of debris packed between outside of the filter and the canister. Avoid using high-pressure air, which could force dirt through the filter into the intake tract.

   Note: This cleaning process prevents debris from migrating into the intake when you remove the filter.

3. Remove and replace the filter.

   Important: Do not clean the used element to prevent damaging the filter media. Inspect the new filter for shipping damage, checking the sealing end of the filter and the body. Do not use a damaged element. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister. Do not apply pressure to the flexible center of the filter.

4. Clean the dirt-ejection port located in the removable cover.

5. Remove the rubber outlet valve from the cover, clean the cavity and replace the outlet valve.

6. Install the cover orienting the rubber outlet valve in a downward position—approximately between the 5 o’clock to 7 o’clock positions when viewed from the end.

7. Secure the latch.

The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started.

Important: Check the engine oil daily. If the engine-oil level is above the Full mark on the dipstick, the engine oil may be diluted with fuel;If the engine oil level is above the Full mark, change the engine oil.

The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the Add mark on the dipstick, add oil to bring the oil level to the Full mark. Do not overfill the engine with oil.

Important: Keep the engine oil level between the upper and lower limits on the dipstick; the engine may fail if you run it with too much or too little oil.

1. Perform the pre-maintenance procedure; refer to Maintenance Safety.

2. Open the hood.

3. Remove the dipstick, wipe it clean, and install it (Figure 31).

   

   Figure 31

   1. Dipstick
   2. Oil-fill cap

4. Remove dipstick and check the oil level on dipstick. The oil level should be up to the FULL mark.

5. If the oil level is below the FULL mark, remove the fill cap (Figure 31) and add oil until level reaches the FULL mark on dipstick.

6. Install the oil fill cap and close the hood.

   4. Jam nuts

3. If necessary, adjust the position of the jam nuts on the throttle-control cable until the speed-control lever contacts the high-speed screw when the throttle-control lever is in the FAST (detent) position (Figure 33).

4. Ensure that the cable jam nuts are fully tightened after the adjustment.

Service the water separator as shown in Figure 34.

After replacing the water separator, turn the key to ON for 10 seconds, but do not start the engine. Turn the key off and repeat this 2 more times.

Figure 34

You must bleed the fuel system before starting the engine if any of the following have occurred:

• Initial start up of a new machine

• The engine has ceased running due to lack of fuel.

• Maintenance has been performed upon fuel system components (i.e., filter replaced, separator serviced, etc.)

1. Perform the pre-maintenance procedure; refer to Maintenance Safety and ensure that the fuel tank is at least half full.

2. Open the hood and secure it with the prop rod.

3. Open the air-bleed screw on the fuel-injection pump (Figure 35) with a 12 mm wrench.

   

   Figure 35

   1. Bleed screw

4. Turn the key in the ignition switch to the ON position. The electric fuel pump will begin operation, thereby forcing air out around the air bleed screw. Leave the key in the ON position until a solid stream of fuel flows out around the screw.

5. Tighten the screw and turn the key to the OFF position.

Note: The engine should start after you perform this procedure. However, if engine does not start, air may be trapped between injection pump and the injectors; refer to Bleeding Air from the Fuel Injectors.

Note: Use this procedure only if the fuel system has been purged of air through normal priming procedures and the engine does not start; refer to Bleeding the Fuel System.

1. Loosen the pipe connection to the No. 1 nozzle and holder assembly (Figure 36).

   

   Figure 36

   1. Fuel injectors

2. Turn the key in the key switch to the ON position and watch the fuel flow around the connector. When you observe a solid flow of fuel, turn the key to the OFF position.

3. Tighten the pipe connector securely.

4. Repeat steps 1 through 3 for the remaining nozzles.

Drain and clean the fuel tank every 2 years. Also, remove and clean the in-line strainers after draining the tank. Use clean diesel fuel to flush out the tank.

Important: Drain and clean the tank if the fuel system becomes contaminated or if you store the machine for an extended period of time.

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

Keep the top of the battery clean. If you store the machine in a location where temperatures are extremely high, the battery will run down more rapidly than if the machine is stored in a location where the temperature is cool.

Keep the top of the battery clean by washing it periodically with a brush dipped in ammonia or bicarbonate of soda solution. Flush the top surface with water after cleaning it. Do not remove the fill caps while cleaning the battery.

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

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.

If the machine stops or has other electrical-system issues, check the fuses. Grasp each fuse in turn and remove them 1 at a time, checking to see if any are blown. If you need to replace a fuse, always use the same type and amperage rated fuse as the 1 you are replacing; otherwise, you could damage the electrical system (refer to the decal next to the fuses for a diagram of each fuse and its amperage).

The traction-unit fuses are located under the seat (Figure 37).

Figure 37

1. Location of the fuse block

The cab fuses are located in the fuse box on the cab headliner (Figure 38).

If you store the machine for more than 30 days, remove the battery and charge it fully. Either store it on a shelf or on the machine. Leave the cables disconnected if you store it on the machine. Store the battery in a cool atmosphere to avoid quick deterioration of the charge in the battery. To prevent the battery from freezing, ensure that it is fully charged. The specific gravity of a fully charged battery is 1.265 to 1.299.

The machine comes with an electronic controller which controls most of the machine functions. The controller determines what function is required for various input switches (e.g., seat switch and key switch) and turns on the outputs to actuate solenoids or relays for the requested machine function.

For the electronic controller to control the machine as desired, each of the input switches, output solenoids, and relays must be connected and functioning properly.

Use the Diagnostic ACE display tool and overlay to help verify and correct electrical functions of the machine. Contact your Toro Distributor for assistance.

The interlock switches prevent the engine from cranking or starting unless the traction pedal is in the NEUTRAL position and the PTO is disengaged. The engine should stop when you press the traction pedal when you are not sitting on the seat or if the parking brake is engaged.

Maintain the air pressure in the front and rear tires. The correct air pressure is 172 kPa (25 psi) in the rear tires and 103 kPa (15 psi) in the front tires. If a cab is installed on the machine, the front and rear tires should be inflated to 172 kPa (25 psi). Uneven tire pressure can cause an uneven cut. Check the tires when they are cold to get the most accurate pressure reading.

   Figure 42

   1. Steering-selector switch

2. On a paved or dirt surface, turn the steering wheel to the left or right and continue turning until all 4 wheels have stopped turning. Automatic synchronization of the wheel alignment should occur.

   Important: Doing this procedure on turf can result in turf damage directly under each of the turning tires.

The coolant reservoir is filled at the factory with a 50/50 solution of water and ethylene glycol base extended-life coolant.

Important: Use only commercially available coolants that meet the specifications listed in the Extended Life Coolant Standards Table.Do not use conventional (green) inorganic-acid technology (IAT) coolant in your machine. Do not mix conventional coolant with extended-life coolant.

Coolant Type Table

Extended Life Coolant Standards

Important: Coolant concentration should be a 50/50 mixture of coolant to water.

• Preferred: When mixing coolant from a concentrate, mix it with distilled water.

• Preferred option: If distilled water is not available, use a pre-mix coolant instead of a concentrate.

• Minimum requirement: If distilled water and pre-mix coolant are not available, mix concentrated coolant with clean drinkable water.

The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol anti freeze. Check the level of the coolant in the expansion tank at the beginning of each day before starting the engine. The capacity of the cooling system is 7.5 L (6 US qt).

1. Check the level of the coolant in the expansion tank (Figure 43). The coolant level should be between the marks on the side of the tank.

2. If coolant level is low, remove the expansion tank cap and replenish the system. Do not overfill.

3. Install the expansion-tank cap.

5. Clean the screen, air-conditioning duct, fans, and fan panel using low-pressure air no greater than 276 kPa (40 psi).

   Important: Do not use water to clean the condenser because moisture on the components attracts dirt and dust, which make the components more difficult to clean.

6. Install the fan-panel assembly and fans to the underside of the cab top with the 2 knobs that you loosened and removed in step 4.

7. Connect the cord for the fans that you disconnected in step 3 into the outlet.

8. Install the air-conditioning screen in the opening in the top of the cab and secure it by closing the 4 tabs on the screen.
