Gravity just wasn't enough to get the fluid to fill the pump. Pre-filling components and proper bleeding of the hydraulic system during start-up will usually eliminate free air. “Bleeding” a hydraulic line refers to the process of pumping hydraulic fluid through the lines to remove any air pockets that may be trapped amidst the fluid. But if the system is left to purge itself, ‘filling the voids’ can make a significant difference to the volume of air that has to be expunged.
