Maintenance — Engine Cooling System

Cleaning Cooling System

1.Perform the “Mandatory Safety Shutdown Procedure” on page4

2.Allow engine to cool.

3.Open engine cover.

4.Clean radiator and oil cooler by blowing air or high pressure water through the fins.

IMPORTANT: High pressure may bend the fins. Proceed with caution. Blow air in opposite direction of fan direction to dislodge debris.

Draining/Refilling Cooling System

1.Perform the “Mandatory Safety Shutdown Procedure” on page4.

2.Allow engine to cool.

3.Open engine cover.

Warning

Do not remove radiator cap when the coolant is hot. Serious burns may occur.

4.Slowly loosen radiator cap (1, Figure 7) and allow pressure to escape. Remove cap.

5.Remove the engine access panel. See “Changing Engine Oil and Filter” on page20, step 4.

6.Position a collection container, capacity 8liters (2gallons), underneath the radiator drain.

7.Open radiator drain valve (1, Figure 8). Drain valve is located at bottom of radiator, above frame member. Drain valve opening faces the front of the machine.

8.Drain the coolant into the container.

IMPORTANT: Always dispose of coolant according to environmental laws. DO NOT pour onto the ground or down a drain.

9.Close radiator drain valve.

10.Replace engine access cover.

11.Completely fill the radiator with premixed coolant. See “Fluid Capacities/Lubricants” on page11 for coolant specification.

12.Reinstall radiator cap.

13.Complete all steps in “Checking Coolant Level” on page23.

14.Run the engine until it is at operating temperature.

15.Perform the “Mandatory Safety Shutdown Procedure” on page4.

16.Allow the engine to cool.

17.Open the engine cover.

18.Check the coolant level in the expansion reservoir. The reservoir must be 1/3 to 1/2 full for a cold engine and 2/3 to 3/4 full for a hot engine.

Fuel System WARNING

Only use proper grade diesel fuel. See “Fluid Capacities/Lubricants” on page11. Diesel fuel is flammable. Keep the machine away from open flames. Do not smoke when refueling or when working on the engine. Stop the engine before fueling. Failure to follow instructions can cause fire and result in injury or death.

Adding Fuel

1.Perform the “Mandatory Safety Shutdown Procedure” on page4.

2.High quality diesel fuel is required for correct engine performance. See “Fluid Capacities/ Lubricants” on page11.

Maintenance — Fuel System

4.Add fuel into fuel filler neck (2).

IMPORTANT: Only use low sulfur or ultra-low sulfur diesel fuel. See “Fluid Capacities/Lubricants” on page11.

Changing Fuel Filter

1.The fuel filter (1, Figure 10) is located in the fuel line before the fuel pump. Access the fuel filter by opening the engine cover and tilting the operator’s platform. See “Tilting the Platform” on page61. Replace the fuel filter at regular intervals specified. See “Maintenance Schedule” on page18.

3.Remove fuel cap (1, Figure 9).

1.Perform the “Mandatory Safety Shutdown Procedure” on page4.

2.Shut off the fuel supply by turning the fuel shut-off valve on top of the water separator to OFF.

3.Remove the fuel filter.

4.Lubricate new fuel filter gasket with diesel fuel.

5.Install and tighten the filter 3/4 turn past point the where the gasket contacts the filter head.

6.Turn shut-off valve on water separator to ON.
