45. Select two hoses:
HP-9JF154
3/8" HOSE X 154" 9/16 JICF ENDS
One with orange tie or “R” tag, and one without.

marking to sequence valve port R.
47. Connect the unmarked hose to sequence valve
port C
48. Route the hoses under the clamp on the rear
face of the wing lock lug. Leave clamps lightly snug
at this time, to allow for sag and slack adjustment at
step 52.
49. Route the hoses under the clamp at mid-wing
near the fold cylinder rod end.
50. Route the hoses to the front of the wing, under the
adjustment valve assembly and under the outer
wing clamp
.

elbow fitting at the rod end.

Left Sag and Slack:
• Allow just enough sag at the wing pivot so that the
hose is near, but no lower than the wing pivot pin .
• Where the hoses naturally cross each other at the
cylinder, secure a cable tie.
• Add a second tie approximately 40cm (16in) away, to
bundle the hoses.
• Create enough slack at this location for a loop no
higher than the eyebolt on the gauge wheel. The rod
end hose must follow the rod end of the cylinder as it
swings out and toward the rear during marker exten-
sion.
• Balance remaining slack at the adjustment valves and
at the sequence valve.
• Check that all slack is clear of moving parts.
