Bleeding the System
Before any measurements can be made, the hydraulic system needs to be primed
and bled free of air. During the following operations, prepare for fluid spillage and
provide a suitable receptacle for collecting the spillage.
(1) Prepare for use as detailed on page 46.
(2) Fill a suitable container with the required hydraulic fluid and place the
priming inlet assembly hose into the fluid.
(3) Open the bleed valve on the Unit Under Test (UUT). If possible, fit a hose to
the bleed point and place this in a container of the same fluid.
(4) Use the priming pump, to pump hydraulic fluid into the instrument and the
connected system. Monitor the hydraulic fluid level, ensuring that the
priming hose stays below the fluid level and is not allowed to suck in air.
Top-up hydraulic fluid level as necessary.
