Hydraulics

The idea behind the hydraulic press (machine or bench press) is that a liquid, when displaced, will exert pressure or force equally across the surface it is forced against. Because of this, hydraulic presses are commonly used for automotive and industrial repair shops, where pressing, bending, straightening, and forming is required.

Yes, and this is determined by the manufacturer.

Hydraulic pump

Wires stretch and sag. Hydraulic fluids transfer force with far smaller losses.

most likely your charge pump or main pumps are not working or being driving. From as simple as the belt not spinning them, to something after pulley, that is sheared or broken

Archimedes' Principle

I have 4 takara chairs around the 50's vintage. 3 of them dont go up or down. I dismantled 3 of them and the hydraulic cylinder has seized. There was plenty of oil in them but the piston is stuck in the bottom of the cylinder. The cylinder is sealed at the end with a crimped end cap so the cant be repaired. I am going to drill a hole in the end cap and belt the piston out and see what happens. I have found out you cant buy parts for them!
