5. Remove the drain plug from the hydraulic reservoir
(located underneath the reservoir), and drain the
reservoir (Figure 90).
Note: The capacity of the reservoir is approximately
75.7 L (20.0 US gal); the capacity of the complete
system is approximately 98.4 L (26.0 US gal).
6. Examine the condition of the O-ring on the drain plug.
Note: Replace the O-ring if it is worn or damaged.
7. Install the drain plug (Figure 90).
Important: Change the hydraulic-pressure
and hydraulic-return filters when you change
the hydraulic fluid; refer to Changing the
Hydraulic-pressure Filter (page 62) and Changing
the Hydraulic-return Filter (page 63).
Filling the Hydraulic-fluid Reservoir
1. Fill the hydraulic-fluid reservoir with the specified
hydraulic fluid until the fluid level is at the midpoint of
the sight gauge (Figure 91).

2. Sight gauge
2. Remove the right-side panel; refer to Removing the
Side Panels (page 35).
3. Remove the breather hose, clean and inspect it, then
install the hose.

4. Install the right-side panel; refer to Installing the Side
Panels (page 36).
5. Clean the fill cap/breather with solvent.
6. Install the fill cap/breather (Figure 91).
7. Start the engine and let it idle for approximately 2
minutes.
8. Stop the engine and remove the ignition key.
9. Check around the pressure and return filters for leaks.
10. Check the drain plug for leaks.
11. Check the level of the hydraulic fluid and fill the
reservoir to the middle of the sight glass as needed.
Changing the Hydraulic-pressure Filter
Service Interval: Every 500 hours
Note: You can access the hydraulic-pressure filter from
under the right side of the machine, behind the hydraulic
reservoir (Figure 92).
1. Place a container under the hydraulic-pressure filter
(Figure 92).

hydraulic fluid
2. Sharp object
2. Puncture the bottom of the hydraulic-pressure filter,
and allow the residual hydraulic fluid to drain into the
container (Figure 92).
Note: Use a tapered-center punch or awl to puncture
the filter case.
