I have an 05 Ultrasupreme with hydraulics. Attached is a troubleshooting list for my Equalizer system and a procedure for hand raising the jacks. There should be connections on the pump manifold for the slide outs. By locating the slide out valve and following the jack procedure, you should be able to hand pump the slide in.
You should/may have a short metal pipe in the hydraulic bay that is the pump handle.
