4 1205-NT Folding Marker Option 113-549M 5/5/09
Great Plains Mfg., Inc.
For Dual Markers
With a Sequence Valve
NOTE: JIC fittings do not require high torque. JIC and O-
Ring fittings do not require sealant. Always use liquid pipe
sealant when adding or replacing pipe thread fittings. To
avoid possible danger of cracking hydraulic fittings from
overtightening, Do not use plastic sealant tape.
If your kit includes a sequence valve (#2), attach it to the valve
mount (#12) located at the center rear of the tongue with two
3/8" x 3/4" long bolts (#3) and 3/8" lock washers (#4). Install
a 9/16" male o-ring boss x 9/16" male JIC adapter (#8) into
each end of the cylinder. Assemble a 9/16" female JIC x 9/16"
male JIC 90 degree elbow (#1) into each of the six ports on
the sequence valve and each end of the marker cylinders.
Two elbows (#1) are required on the base end of the marker
cylinders to offset the hoses around the marker rest post.
Route the 51" long hydraulic hoses (#6) from the elbows at
the ports on the sequence valve marked C1 & C2 to the el-
bows on the base ends of the marker cylinders. The 70" long
hydraulic hoses (#7) attach to the elbows on the valve ports
marked R1 & R2 and the elbows on the rod end of the marker
cylinders. The two 184" long hoses (#5) attach to the remain-
ing two elbows (#1) on the valve opposite the marker ports
and are routed through the tongue to the hitch.
Tie the hoses to the coulter frame tube with the plastic cable
ties (#9) provided.
