Single/Dual Markers without Sequence Valve
Refer to Figure 26
1. Fold markers manually into transport position when
charging hydraulic system for the first time.
2. Disconnect cylinder pin (1) from rod end of
cylinders and marker link arms (2). Swing marker
link arm up and out of the way.
3. Connect hoses to tractor remote hydraulic outlets.
4. Loosen hose hydraulic fittings at rod end of marker
cylinders (3).
5. With tractor at idle speed, slowly work tractor
remote lever in the direction which would retract the
cylinder.
Note: Do not try to retract cylinder. The goal is to push
air from the lines leading to the cylinder. The
position of the sequence valve determines which
cylinder will react first.
6. When the air is expelled, oil will seep out around a
loosened fitting. Tighten the hose fitting.
7. Move tractor remote lever to fully extend cylinder
and hold for a few seconds.
8. If you have dual markers, repeat steps 4 through 6.
9. When the system is bled, move the tractor remote to
fully extend marker cylinders.
10. Reconnect cylinders to marker link arms.
