Changing Hydraulic Oil

Draining Oil:

1. Lower header to ground. Retract hydraulic cylinders of reel and unloading auger.
2. Remove drain plug (A) and drain the oil into an appropriate container.
3. Disconnect the hoses from all hydraulic cylinders, the control return hose and the reel drive system hoses from the flow regulating valve. Drain oil at all these points.

NOTE: Before disconnecting the hoses, clean the connections thoroughly.


4. After draining all oil, reconnect all connections and reinstall the reservoir drain plug (A).

Refilling:

NOTE: Only use recommended oil (see "Fuel, Lubricants and Coolant" section). Carefully clean area around filler opening.

1. Refill with fresh hydraulic oil through filler neck (B) until oil reaches the center of sight glass (A).
2. Run engine. Raise and lower the unloading auger, reel and header a number of times and turn the steering wheel in both directions several times to bleed off remaining air from the circuit.
3. Engage the threshing unit and the header and activate the cylinder speed control several times.
4. Inspect all lines and connections for leaks. Comply with all safety rules.
5. Check oil level in reservoir with all hydraulic cylinders completely retracted. If necessary, add oil to reservoir until correct level is reached.
