Bleeding the System (Figure A2)

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 62.

2.

Fill a suitable container with clean hydraulic fluid and place the bleed hose assembly
(1) connected to the priming port into the fluid.

3.

Open the UUT bleed valve (5) and, if possible, fit a hose to the bleed point and locate
the hose end in a container of the same hydraulic fluid.

4.

Use the priming pump (2), to pump hydraulic fluid into the instrument and the
connected system. Monitor the hydraulic fluid level, ensuring that the bleed hose
assembly (1) stays below the fluid level and is not allowed to suck in air. Top-up
hydraulic fluid level as necessary.
