FILLING THE HYDRAULIC RESERVOIR (Figure 29)
1. Access to the hydraulic reservoir is located in the engine
compartment.
2. Open the hydraulic reservoir breather filter cap.
3. Remove any debris that is in the breather filter cap
screen.
4. Fill the reservoir until the fluid is at the “FULL” line
on the hydraulic fluid sight gauge. The sight gauge
is located on the center side of the hydraulic res
ervoir.
5. Close the hydraulic reservoir breather filter cap.
6. Close the engine compartment cover.

CLEANING THE HYDRAULIC SYSTEM
1. Put a drop cloth on the floor.
2. Drive the machine onto the drop cloth.
3. Set the parking brake.
4. Open the engine covers.
5. Put a container under the reservoir drain to catch the reservoir fluid. Pivot the reservoir out.
6. Remove the drain plug. The reservoir fluid will drain. Do not use the drained fluid to refill the

6. Remove the drain plug. The reservoir fluid will drain. Do not use the drained fluid to refill the
hydraulic reservoir. Dispose of the used fluid.
7. Flush the interior of the hydraulic reservoir with clean fluid.
8. Put the reservoir plug, removed in step six, back in the hydraulic tank drain and tighten it. A pipe
8. Put the reservoir plug, removed in step six, back in the hydraulic tank drain and tighten it. A pipe
thread sealer is required on the plug.
9. Open the breather filter cap.
10. Fill the reservoir with new SAE 30W non detergent automotive transmission fluid. The capacity of the tank is
10. Fill the reservoir with new SAE 30W non detergent automotive transmission fluid. The capacity of the tank is
4.7 gal (17.79 liters). Fill to the “FULL” line on the hydraulic fluid sight gauge.
11. Close the breather filter cap. Rotate the reservoir into the engine compartment.
12. Replace the engine covers.
12. Replace the engine covers.
REPLACING THE RETURN FILTER ELEMENT
1. Replace the return filter element after 250 hours of
machine run time.
2. Unscrew the fasteners from the filter assembly
cover and retain.
3. Remove the cover and the compression spring
and retain.
4. Discard the old filter element.
5. Position the new filter element inside the filter body.
6. Put the compression spring in position. Wipe the
cover magnet free of any metal filings or debris.
7. Place O-ring (moisten with clean hydraulic fluid)
and cover into position.
8. Reattach fasteners to the filter cover.
9. Clean any hydraulic reservoir fluid spills. The fluid
can damage painted surfaces of the machine.
