Genie z60/34 selfleveling delay

Hi, I'm servicing a Z60/34, serial number Z6013-12907, and when I raise the primary cylinder, the self-leveling delays. I've been thinking it's due to a lack of air bleeding. I've read the manual, and it tells me to connect a hydraulic hose between the two test ports on the fixed end of the slave cylinder, but I don't have a reference image or a clear idea of how to do it. Could someone help me?

Has there been a repair done on the system recently? The master/slave cylinder operation is usually off due to internal cylinder leakage of one of the cylinders. The system should self-bleed.

It has been confirmed that the master and slave cylinders are in good condition, the counterbalance valves work well, however, when the primary cylinder is raised, the basket begins to level late and when it is lowered, it lowers more than normal.

How did you prove the cylinder seals in each were good?
We removed the master cylinder and proceeded to disassemble it to change the seals. We then tested it in a hydraulic unit to verify that there were no internal leaks.
