Rv Screen Room I Have An Rv With An Hwh 310 Series Leveling System, Where Is The Oil Dipstick On The Hydraulic Pump?

I have an rv with an hwh 310 series leveling system, where is the oil dipstick on the hydraulic pump? - rv screen room

And what is the network's search screen, an elbow that is attached to the end of the pump attatched? How much oil and what it takes? Thanks for any help.
