13. Place a receptacle under the hydraulic reservoir drain plug (10). The recep-
tacle must be large enough to hold 35 gallons (132 liters) of oil. Remove
the drain plug and allow the oil to drain into the receptacle. Transfer the oil
to a container with a cover and label the container as used oil. Dispose of
properly.
14. Re-install the drain plug (10) into the reservoir. Torque the drain plug to
25-40 lb-ft (34-54 Nm)
15. Remove the fill cap (11) located toward the front of the hydraulic reservoir.
It is recommended that the fill port (12) be used to add oil. The oil is added
through the filter which will help to prevent contaminates from entering the
hydraulic system. Fill with hydraulic oil (ISO Grade 46 Hydraulic Oil) until
the oil level is in the center of the sight glass (13) when oil is cold and all
cylinders retracted. Reservoir capacity is 33.5 gallons (127 liters). Re-
install the fill cap (11). DO NOT add oil through the hydraulic oil tank
breather (14).
16. Close and latch the engine cover.
17. Run vehicle and operate all hydraulic functions. Cycle all modes of controls
to purge air from the system.
18. Check for leaks.
