The CD manuals are available through Deere's 800 number.
Didn't spot anything really new in the manual - however I realized after I said I'd look that I only have the tech manual for the tractor, not the loader itself. However, here is the basic procedure for the tractor's hydraulic system - and other than the fuel solenoid bit (haven't quite figured the reason out for that yet) - it boils down to cycling the relevant system (under some load if possible) and checking the fluid level just like everyone already said.
Hydraulic System Bleed Procedure -- Reason: To remove air trapped in the hydraulic system which will prevent proper operation. (Special or Essential Tools: • BW13586 Ballast Box)
Procedure: NOTE: Fill the new hydraulic oil filter with new oil before installing.
1. Install a new hydraulic oil filter.
2. Fill the transaxle with specified JDM J20D (preferred) or J20C oil to the proper level on dipstick.
3. Disconnect plug (A) to fuel shutoff solenoid. M91946
4. Turn the key to START and hold for 10 seconds. Turn the key to OFF.
5. Reconnect wires to fuel shutoff solenoid.
6. Raise machine front end and support on suitable stands.
7. Start the engine and run at low idle.
8. Slowly turn the steering wheel left and right until wheels turn smoothly indicating that any trapped air has been bled back to the reservoir.
9. Operate rockshaft several times until it operates smoothly.
10.Stop the engine and check the hydraulic reservoir oil level. Fill as needed. Check all line connections for leaks; tighten if necessary.
11.Lower the machine to the ground.
12.(eHydro machines) Drive machine in forward and reverse several times until transmission operates smoothly.
