Re-Connect Hydraulic Feed Lines
Avoid High Pressure Fluids
!
WARNING
Escaping fluid under pressure can penetrate the skin, causing
serious injury. Avoid the hazard by relieving pressure before
disconnecting hydraulic lines. Use a piece of paper or card-
board, NOT BODY PARTS, to check for suspected leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. If an accident occurs, see a
doctor immediately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene may
result.
IMPORTANT !
When first opening either of the hoses at the exist-
ing marker sequence valve, do so slowly and care-
fully. Wear gloves. Bleed off pressure before
completely removing connectors from fittings.
Although the marker circuit was floated at step 2, some
hoses may still contain hydraulic fluid at high pressure.
Refer to Figure 19 (this page) and Figure 20 (page 10)
53. At the marker sequence valve disconnect the
top hydraulic feed hose .
54. Slowly loosen both JIC connectors of the feed lines
, at the Front of the sequence valve, and bleed
off any residual pressure.
55. Disconnect the bottom hose , and reconnect it to
the lower Left (face) port of the selector valve
. Tighten both the ORB and the JIC connections
at this port .
56. Disconnect the top hose , and reconnect it to the
top Left (face) port of the selector valve .
Tighten both the ORB and the JIC connections at
