For Markers
Without a Sequence Valve
(Right & left hand markers without sequence valve are purchased seperately)
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.
Refer to Figure 3 and install a 9/16" male o-ring boss x 9/16"
male JIC adapter (#6) into each end of the cylinder. Assemble a
9/16" female JIC X 9/16" male JIC 90 degree elbow (#1) onto
each of these adapters. Two elbows (#1) are required on the
base end of the marker cylinder(s) to offset the hoses around the
marker rest post. Assemble the needle valve (#2) and the 9/16"
female JIC x 3/8" male pipe adapter (#3) to the elbow at the rod
port. Attach the 236" long hose(s) (#5) to the elbows at the base
end of the marker cylinders and the 252" long hose(s) (#4) to the
needle valves at the rod end of the cylinders. Route the hoses to
the hole on the left rear side of the tongue and to the hitch.
Tie the hoses to the coulter frame tube with the plastic cable ties
(#7) provided.
