Note: The glow plug light illuminates for 6 seconds when you turn the ignition key to the RUN position. Turn the ignition to the START position after the light goes out.

Important: Use starting cycles of no more than 15 seconds per minute to avoid overheating the starter motor.

Important: Operate the machine with the throttle lever in the SLOW position in both the forward and reverse directions for 1 to 2 minutes after changing the engine oil, overhauling either the engine, transmission, or wheel motor, and when you start the engine for the first time. Operate the lift lever and PTO lever to ensure that they operate properly. Shut the engine off, check fluid levels, and check for oil leaks, loose parts, and any other noticeable malfunctions.

Figure 20

Note: Leave the throttle midway between the SLOW and FAST positions until the engine and hydraulic system warm up.

The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the FAST throttle position when running powered attachments.

1. Release the parking brake.

   Note: The engine shuts off if you move the motion-control levers out of the NEUTRAL-LOCK position with the parking brake engaged.

2. Move the levers to the center, unlocked position.

3. Drive the machine as follows:

   • To move straight forward, slowly push the motion-control levers forward (Figure 21).

   • To move straight rearward, slowly pull the motion-control levers rearward (Figure 21).

   • To turn, slow the machine by pulling back on both levers and then push forward on the lever on the opposite side from which you want to turn (Figure 21).

   • To stop, pull the motion-control levers to the NEUTRAL position.

   Note: The farther you move the motion-control levers in either direction, the faster the machine moves in that direction.

You can adjust the height of cut from 2.5 to 15.8 cm (1 to 6 inches) in 6 mm (1/4 inch) increments by relocating the stop pin into different hole locations.

1. With the engine running, push the deck-lift switch up until the cutting unit is fully raised and release the switch immediately (Figure 23).

2. Rotate the stop pin until the roll pin in it lines up with the slots in the holes in the height-of-cut bracket and remove it (Figure 26).

3. Select a hole in the height-of-cut bracket corresponding to the height of cut desired, insert the pin, and rotate it down to lock it in place (Figure 26).

   Note: There are 4 rows of hole positions (Figure 26). The top row gives you the height of cut listed above the pin. The second row down gives you the height listed plus 6 mm (1/4 inch). The third row down gives you the height listed plus 12 mm (1/2 inch). The bottom row gives you the height listed plus 18 mm (3/4 inch). For the 15.8 cm (6 inch) position, there is only 1 hole, located in the second row. This does not add 6 mm (1/4 inch) to the 15.8 cm (6 inch) position.

4. Adjust the anti-scalp rollers and skids as required.

In an emergency, you can move the machine a very short distance by actuating the bypass valves in the hydraulic pump and pushing the machine.

Important: Always push the machine by hand and never a long distance. Never tow the machine, because damage to the hydraulic system may occur.

Important: The bypass valves must be open whenever you push or tow the machine. Close the valves once you have pushed or towed the machine to the desired location.

1. Lift the seat; refer to Unlatching the Seat

2. Locate the bypass valves (Figure 27) and rotate each bypass valve counterclockwise 1 turn.

   Note: This allows hydraulic fluid to bypass the pump, enabling the wheels to turn.

   Important: Do not rotate the bypass valves more than 1 turn. This prevents valves from coming out of the body and causing fluid to run out.

   

   Figure 27

   1. Right bypass valve
   2. Left bypass valve

3. Ensure that the parking brake is disengaged and push the machine to the desired location.

4. Close the valves by rotating each valve 1 clockwise turn (Figure 27).

   Note: Do not overtighten the valves.

5. Torque the valves to approximately 8 N∙m (71 in-lb).

   Important: Ensure that the bypass valves are closed before you start the engine. Running the engine with open bypass valves causes the transmission to overheat.

Use a heavy-duty trailer or truck to haul the machine. Ensure that the trailer or truck has all the necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

1. If you are using a trailer, connect it to the towing vehicle, and connect the safety chains.

2. If applicable, connect the trailer brakes.

3. Load the machine onto the trailer or truck; refer to Loading the Machine.

4. Shut off the engine, remove the key, engage the parking brake, and close the fuel valve.

5. Use the tie-down loops on the machine to securely fasten it to the trailer or truck with straps, chains, cable, or ropes (Figure 28).

The machine has grease fittings that you must lubricate regularly with No. 2 lithium grease. Lubricate more often in dirty or dusty conditions because dirt can get into the bearings and bushings and cause accelerated wear.

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

2. Pump grease into the fittings.

3. Wipe off excess grease.

Note: Improper wash-down procedures can negatively affect bearing life. Do not wash down the machine when it is still hot and avoid directing high-pressure or high-volume spray at the bearings or seals.

The gear box is designed to operate with SAE EP90W gear lube. Although the gearbox comes from the factory with lubricant, check the level of the lubricant in the cutting unit before operating it and as recommended in the Daily Maintenance Checklist.

1. Check the air-cleaner body for damage, which could possibly cause an air leak. Replace a damaged air-cleaner body.

2. Check the air-intake system for leaks, damage, or loose hose clamps.

3. Service the air-cleaner filter (Figure 32).

   Important: Do not over-service the air filter.

4. Ensure that the cover is seated correctly and seals with the air-cleaner body.

Note: If the foam gasket in the cover is damaged, replace it.

Important: Avoid using high-pressure air, which could force dirt through the filter into the intake tract.

Important: Do not clean the used filter to avoid damage to the filter media.

Important: Do not use a damaged filter.

Important: Do not apply pressure to the flexible center of the filter.

Figure 33

In addition to the listed service interval, drain and clean the tank if the fuel system becomes contaminated or if you are storing the machine for an extended period. Use clean fuel to flush out the tank.

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

1. Park the machine on a level surface. Ensure that the fuel tank is at least half full.

2. Unlatch and raise the hood.

3. Place a rag under the air-bleed screw on the fuel-injection pump and open it (Figure 38).

   

   Figure 38

   1. Fuel-injection-pump bleed screw

4. Turn the ignition key to the ON position.

   Note: The electric fuel pump begins operation, thereby forcing air out at the air-bleed screw.

   Caution

   The engine may start during this procedure. Moving fans and belts in a running engine can severely injure you or bystanders.

   Keep hands, fingers, loose clothing/jewelry, and hair away from the engine fan and belt during this procedure.

5. Leave the key in the ON position until a solid stream of fuel flows out around the screw.

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

   Note: Normally, the engine should start after you bleed the fuel system. However, if the engine does not start, air may be trapped between injection pump and injectors; refer to Bleeding Air from the Injectors.

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

1. Place a rag under the pipe connection coming from the injection pump to the No. 1 injector nozzle as illustrated in Figure 39.

   

   Figure 39

   1. Pipe connection from the injection pump to the No. 1 injector nozzle

3. Turn the ignition key to the START position and watch the fuel flow around the connector.

   Caution

   The engine may start during this procedure. Moving fans and belts in a running engine can severely injure you or bystanders.

   Keep hands, fingers, loose clothing/jewelry, and hair away from the engine fan and belt during this procedure.

4. Tighten the pipe connector securely when it attains a solid flow.

5. Turn the key to the OFF position.

6. Repeat this procedure for the remaining nozzles.

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 you are storing the machine more than 30 days, remove the battery and charge it fully. Either store it on a shelf or on the machine. Do not connect the cables if you store it on the machine. Store the battery in a cool environment to prevent the battery from discharging rapidly. To prevent the battery from freezing, make sure it is fully charged. The specific gravity of a fully charged battery is 1.265 to 1.299.

The fuses are located under the control panel. Access them through the side panel cover (Figure 40). To open the side panel cover, release the 2 latches and pull out on it.

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 if any are blown.

Important: If you need to replace a fuse, always use the same type and amperage-rated fuse as the one 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 (Figure 41).

Note: If a fuse blows frequently, you may have a short in the electrical system and should have it serviced by a qualified service technician.

8. Tighten the locknut until the wheel no longer spins freely, then back it off just until the wheel spins freely.

9. Attach a grease gun to the grease fitting on the caster wheel and fill it with No. 2 lithium grease.

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 capacity of the cooling system is 7.5 L (6 US qt).

1. Check the level of the coolant in the expansion tank (Figure 44).

   Note: The coolant level should be between the marks on the side of the tank.
