Hydraulic System
Step 9
Turn the volume adjuster wheel fully counter-clockwise until it stops
(this could need at least 29 turns). The indicated pressure reading will
decrease.
Step 10
Slowly operate the priming pump until the pressure reaches 5-10 bar.
Step 11
Turn the pressure release knob a quarter of a turn counter-clockwise to
release the pressure.
Step 12
Slowly operate the priming pump until no air bubbles come out of the
hole in the reservoir center stem.
Note:
It should take 10-15 strokes to remove trapped air from
the system.
CAUTION
Do not continue to operate the pump after air bubbles stop
coming out of the central reservoir stem hole.
CAUTION
Do not remove the blanking plug when the instrument is under
pressure. Before removing the blanking plug, check the instrument pressure
display for pressure. If pressure is observed, turn the pressure release knob
fully counter-clockwise until the pressure display reads zero (gauge sensor) or
atmospheric pressure (absolute sensor).
Step 13
Remove the blanking plug from the test port.
