Edit: the tank I serviced is in the rear right corner when raising the servicing door there.
I don't think you filled the hydraulic reservoir for the slides and leveling system. The pump (#22 in the diagram) is likely a gold cylinder on top, a thick square plate with 4 hoses connected then a black cylinder at the bottom which is the correct reservoir. There is a cap on the tank you can remove and fill with oil. I think it's 1.5" from the top of the fill port, but that is just my memory. There should be a sticker or a fill mark. You can get a 18" rod to stick into the reservoir to see the level like a dip stick.
