BriThe operating controls on mine are two push buttons and a lever. The ramp, when in use doesn't rely on the hydraulic ram to keep it in position - there is a metal bar alongside the ram housing which has rectangular holes in it about every two inches, you raise the ramp slightly higher than you need, then lower it slightly, and a solenoid operated peg pushes into the hole in the bar that is along side it, taking the entire weight of the ramp bed and whatever is on it.
The LH push button on the control panel starts the motor/pump, retracts the peg, and raises the ramp. You then release the button, pull the lever downwards, and the ramp lowers slightly onto the peg.
To lower the ramp, you push the fist button momentarily to raise the ramp slightly and take the load off of the peg. Next, you push the RH button, which powers the solenoid that retracts the peg. This button is held in, and the lever pulled down, which opens the oil return valve, allowing the ramp to descend. To stop the ramp part way down, you release the RH button, peg goes in, then you release the lever, when the peg reaches the bottom of its 2" hole.
Does yours work the same way?
I remember reading how it works (year, maybe years ago) and will have notes somewhere - from memory, simpler than yours - lever up for up, mechanical lock to hold, lever down returns fluid to tank, lowering lift.
Trying to take it one step at a time - getting it to move 1st.
It came in parts - trying not to be too optimistic seeing as the rotary switch internals were literally in bits.
