Marker Tilt-Up
Refer to Figure 57
1.
On the CFM, set all FRAME switches off (down).
2. Set Marker Tilt switch to on (up).
3. Move tractor hydraulic control (lever or switch) for the
marker circuit (typically to Retract). Hold until marker
is raised. Do not leave control in detent.
4. Set Marker Tilt switch to off (down), and leave it in
off position during normal field operations.
Marker Tilt-Down
With both markers in the upright and folded configura-
tion, and the tractor circuit control off/neutral:
1. Set CFM switch Marker Fold to off (down).
2. Set CFM switch Marker Tilt to on (up).
3. Move tractor circuit control to Extend. Hold until
markers are resting in transport cradles.
Marker Unfold (one side)
Refer to Figure 59
1.
Tilt markers up.
2. Set CFM switch Marker Fold to on (up).
3. Move tractor hydraulic control (lever or switch) for the
marker circuit (typically to Extend). Hold until marker
is completely unfolded. Do not leave tractor control in detent.
4. If the marker side operating is not the desired side,
let it unfold part way, and move the tractor’s circuit
control to Retract. When the marker is folded, move
the circuit control to Extend to activate the other side.
During normal field operations, leave CFM switch
Marker Fold on. Other FRAME switches must be OFF.
Both Sides Unfolded
