what do you need to run leimbach hydraulics?

[Lil Giants]

All I see missing from your list is a filter, a must have for a hydraulic system.

The "manometer" is the pressure guage and does not come with the pump. From Leimbach's site Part# OH151S (0-25bar).

To the best of my knowledge, all pumps come preset to 10bar. You'll require a torx#7 to adjust the screw within. I set mine to 15bar & haven't had any problems other than the oil darkens quicker from the higher heat/pressure.
