Single-Marker Hydraulics
IMPORTANT: JIC fittings do not re-
quire high torque. JIC and O-ring fit-
tings do not require sealant. To
avoid cracking fittings or castings
from overtightening, do not use
plastic sealant tape.
Refer to Figure 1.
1. Attach the 90-degree swivel elbow (1)
to the rod end of the marker cylinder
(2). Insert the orfice (3) in the base
end of the marker cylinder (2). Attach
the 90-degree swivel elbow (1) to the
base end of the marker cylinder (2).
2. Uncoil and attach hose (4) to the swiv-
el elbow at the rod end of the marker
cylinder (2). Uncoil and attach hose
(5) to the swivel elbow (1) at the base
end of the marker cylinder (2).
3. Install the two adapters (9) and two el-
bow fittings (7) in the top ports (A2 and
B2) of the manifold valve (8). The
manifold valve is located in rear-cen-
ter of the main frame.
4. Route and connect the two marker
hoses (4 and 5) to the elbow fittings (7).
Route hoses through the frame mem-
ber cut-outs and hose clamps. Route
the hoses parallel to the hoses feeding
the outer gauge-wheel cylinder. See
Figure 1.
Refer to Figure 1.

5. Fine tune the hose placement. Make a generous loop in
both hoses near the folding hinge. This loop should be large
enough to allow the outer wing to flex without the hoses pull-
ing tight. Maintain the loops by clamping the hoses in the
center hole of the existing hose clamps. Use the split rubber
sleeves as bushings between the clamps and the marker
hose. Use the cable ties (6) supplied with the kit to hold the
hoses away from any pinch point.
IMPORTANT: Read and complete Setup Adjustments,
page 7 before folding the markers.
