Draining/Flushing Cooling System

1.Perform the “Mandatory Safety Shutdown Procedure” on page14.

2.Wait until the engine has cooled. Do not remove radiator cap when the coolant is hot. Serious burns could result.

Warning

3.Slowly loosen radiator cap (P, Figure 101) and allow pressure to escape. Remove cap.

4.Position a suitable collection container, with a minimum capacity of 19 L (4 gals.) underneath the radiator.

5.Remove radiator drain plug (X, Figure 102)underneath the radiator and allow the coolant to drain into the container.

Important: Dispose waste coolant according to environmental laws. DO NOT pour coolant onto the ground or down a drain.

6.Replace the drain plug (X) and tighten securely.

7.Fill the radiator with coolant.

Note: Use a low-silicate ethylene glycol-based coolant, mixed with clean water and supplemental coolant additives (SCAs) suitable for heavy-duty diesel engines. See “Fluid Capacities/Lubricants” on page187, “Coolant Compound Mixtures” on page193 and the engine operation manual for additional information.

8.Reinstall radiator cap and tighten securely.

9.Start and run the engine until it reaches operating temperature.

10.Check the coolant level according to “Checking Coolant Level” on page145.

Hydraulic System

Never use your hands to search for hydraulic fluid leaks; use a piece of paper or cardboard to find leaks. Escaping fluid under pressure can be invisible and can penetrate the skin, causing serious injury. If any fluid is injected into your skin, see a doctor at once. Injected fluid MUST be surgically removed, or gangrene may result.

Warning

Checking Hydraulic Oil Level

Check the hydraulic oil level daily before starting the machine, or after every ten hours of use.

1.Perform the “Mandatory Safety Shutdown Procedure” on page14.

2.Wait until the engine has cooled.

3.Open the engine compartment according to “Engine Access” on page136.

4.Check the level of the hydraulic oil:

•Locate sight gauge (Y, Figure 103) in the left engine compartment wall. The oil level should be in the middle (A) of the sight gauge.

5.If the hydraulic oil level is low, remove the hydraulic tank filler cap (H, Figure 104), located in the left engine compartment wall.

Important: Slowly remove the hydraulic oil fill cap (H). Allow the pressure to escape before completely removing the cap.

6.Add hydraulic fluid if required. See “Fluid Capacities/Lubricants” on page187 for proper hydraulic oil grade and type.

Important: Do not mix different types/grades of hydraulic fluids.

7.Reinstall hydraulic tank filler cap (H) and tighten securely.
