Hydraulic System Maintenance WARNING

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.

3.Open the hood.

4.Check the hydraulic oil level by removing the dipstick (1, Figure 15), located on the left in the engine compartment.

6.Slowly remove the oil fill cap (2, Figure 15). Allow the pressure to escape before completely removing the cap.

7.Add hydraulic fluid as required. See “Fluid Capacities/Lubricants” on page11.

Changing Hydraulic Oil and Filter

Replace the hydraulic oil if it becomes contaminated, after major repairs, and after 500 hours or one year of use.

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

2.Open the hood.

3.Slowly remove the oil fill cap (2, Figure 15). Allow the pressure to escape before completely removing the cap.

4.Position a waste oil collection container, capacity 45liters (11gallons), underneath the hydraulic oil reservoir.

5.If hydraulic oil is required, allow the system to cool.

IMPORTANT: Always dispose of hydraulic fluids according to environmental laws or take to a recycling center for proper dispos al. DO NOT pour onto the ground or down a drain.
