Typically we come across the question that the leg pins on a table will function separately when the leg section is removed from the table.  When the table does this, it is functioning correctly.  The reason that the table does this is due to the fact that the two leg cylinders share the same mini valve.  Oil will take the path of least resistance when the leg section is removed.  This results in one leg cylinder filling or draining of oil first and then the cylinder doing the same action faster than the first cylinder.
