1 Load Sense Line Bleeding
Valve
For systems utilizing closed−center
valving and load sensing, the load
sense line must be bled of air near
the pump. This is accomplished us-
ing the push−activated valve on the
load sense line.
Remove the spout cap from the
valve. Attach a 3/16 in. (4.7 mm)
tube to the spout and drain to a suit-
able container. While the unit is run-
ning, operate a crane function with
pressure below 700 psi (4.8 MPa)
and simultaneously press the valve
in. Continue this until all air is re-
moved from the line. Release valve
and replace cap.
