1975 Ford 2000 Hydraulics Bleeding

[99FordStang]

Can anyone help with bleeding instructions for Ford 2000 ? I had a hose go on the backhoe, refilled the fluid, and i apparently have a lot of air in the system because the loader now is having trouble. I have read 2 different opinions
1) No bleeding necessary because the air escapes out of the pump just use the hydraulics.
2) un screw the hard line going into the hyd pump and attach a hose to it back to the fill tank and run until smooth

keep the sump full and just run all the cyls lock to lock several times and it WILL self bleed ...
