Changing Hydraulic Oil Filter

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.Place oil pan under the machine to catch the oil.

5.Unscrew and remove hydraulic oil filter (L, Figure 105).

6.Clean the surface of the filter housing where the element seal contacts the housing. Put clean oil on the rubber gasket of the new filter (L).

7.Install and tighten the filter (L) 3/4 of a rotation past the point where the gasket contacts the filter head.

Changing Hydraulic Oil

The hydraulic oil must be replaced if it becomes contaminated, after major repairs, and after 500 hours or one year 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.Slowly loosen hydraulic oil filler cap (H, Figure 104).

5.Position a waste oil collection container with a capacity of at least 60 L (16 gals.) underneath the hydraulic oil reservoir. Note: The hydraulic reservoir drain plug is accessed from underneath the machine at the left rear corner.

6.Remove the hydraulic reservoir drain plug (O, Figure 106) and allow the oil to drain completely.

Important: Always dispose of hydraulic oil according to environmental laws or take to a recycling center for proper disposal. DO NOT pour onto the ground or down a drain.

7.Unscrew and remove the hydraulic oil filter (L, Figure 105).

8.Clean the surface of the filter housing where the element seal contacts the housing. Put clean oil on the rubber gasket of the new filter (L, Figure 105).

9.Install and tighten the filter (L, Figure 105) 3/4 of a rotation past the point where the gasket contacts the filter head.

10.Reinstall and tighten drain plug (O, Figure 106).

11.Remove hydraulic oil filler cap (H, Figure 104) and fill the hydraulic oil reservoir until the oil level is correct (Y, Figure 103).

Important: See “Fluid Capacities/Lubricants” on page187 for proper hydraulic oil grade and type. Hydraulic oil capacity listed is approximate. Always verify proper oil level. See to “Checking Engine Oil Level” on page137.

12.Start the engine and operate the drive, lift and tilt controls.

13.Stop the engine and check for leaks at the filter and reservoir drain plug.

14.Check the fluid level and add fluid if needed.
