What are these two hydraulic knobs for?

[stevereno359]

What are these two hydraulic knobs for? Also what is the on/off switch for? They are located in the battery compartment. Just bought this 2017 Bighorn 3270RS trailer and the owner is deceased. I have searched through the manuals and Youtube videos, and can't find anything. Do you know where I can find a manual for these knobs?

Thanks!

With those knobs you can control each hydraulic slide. Turn one knob off and one hydraulic slide will not operate. The other knob will be for the other hydraulic slide.
That on/off switch should be for an overhead light in that compartment. The light fixture itself might also have a switch on it.

Peace
