Operating and Assembly Instructions
Operating and Assembly Instructions
5
Most accidents are the result of negligence and
carelessness, usually caused by failure of the operator to follow simple but necessary safety
precautions.Thefollowingsafety precautions are
suggested to help prevent such accidents. The
safe operation of any machinery is a big concern
to consumers and manufactures.Your Flat Fold
Marker has been designed with many built-in
safety features. However, no one should operate
this product before carefully reading this Operators Manual.
General Operation & Repair
1. Never allow the Flat FoldMarkerto beoperat-
ed by anyone who is unfamiliar with the operation of all functions of the unit. All operators
should read and thoroughly understand the
instructions given in this manual prior to moving the unit.
2. Makesuresafetyrules areunderstoodbefore
operating machinery or tractor.
3. Never permit any persons other than the op-
erator to ride on the tractor.
4. Never permit any persons to stand near the
Flat Fold Marker while it is in operation.
5. Regulate your speed to the field conditions,
maintaining complete control at all times.
6. After repairing or adjusting, make sure all
tools and parts are removed from the implement before attempting to operate it.
7. Do not grease or oil machine while it is in op-
eration.
8. Loosefitting clothing should not be worn as it
may catch in moving parts.
9. Never dismount from a moving tractor.
10. Do not leavethe tractor or the implement un-
attended with the engine running.
13. If a hydraulicleak develops,correct it immediately. Escaping hydraulic oil can have extremely high pressure. A stream of high
pressure oil may easily penetrate the skin as
with modern needle-less vaccination equipment - but with the exception that hydraulic
fluid may cause blood poisoning. It is imperative that the connections are tight and that all
lines and pipes are in good condition. If an injury is caused by the escaping hydraulicfluid,
see doctor at once!
14. Use a piece of cardboard or wood to detect
leaks of hydraulic oil under pressure.
15. Be sure to relieveall hydraulicpressure before
disconnecting any lines or pipes between the
implement and the tractor hydraulic system.
Keepall guards and shields in place.
Transporting
1. Use good judgement when transporting tractor and implements on the highway. Always
maintain complete control of the machine.
2. Limit transport speed to 20 mph. Transport
only with a farm tractor of sufficient size and
horse power.
3. Alwaysmakesure flashingsafetylights,“Slow
MovingVehicle”emblem,and reflectorsare in
place and visible prior to transporting the machine on public roads.
4. Know your state and local laws concerning
highway safety and regulations. Comply with
these laws when transporting machinery.
5. Usewarning flags or approved warning lights
at night and during other periods of poor visibility. Do your best to prevent highway accidents
3/20/2003
11. Do not stand between the tractor and the implement during hitching.
12. Detach and store implements in an area
where children normally do not play. Stabilize
implements by using suitable supports and
block wheels.

parts section of this manual for more details and
forpositive identification of related items not mentioned in these instructions.
Refer to Figure 1
1. Lower the hitch to field position. Allow clearance of minimum 9’ on a 15’ drill and 11’ on a
20’ drill from each end of the coulter tool bar
for marker assembly.
2. Usingthe U-bolts (4)with flanged nuts (3),position the adapter mount (5) on the front edge
of the drill frame.Boltthe markermount(1) to
the lower side of the adapter mount (5) using
bolts (2) and flanged nuts (3).
NOTE: The offset of the mount must be in the upward direction.
Refer to Figure 2
3. Installthe marker valvemount (6) close to the
center hitch on the tool bar frame using the Ubolt (10), bracket(11) and flange nut (12). Assemble the valve (7) to the mount with the 4port side downwardusing two 3/8" x 3/4" long
bolts (8) and lock washers (9).

the mount and out the opening in the inside
end of the mount. Slide the cylinder and first
sectionassembly(1) into the mount and manually swing the first section into the lowered
position.Bolt the flanges of the assembly and
mount together with four 5/8" x 2" long bolts
(2), lock washers(3), and nuts (4) in each
mount.
5. Routethe hoses alongthe coulter frame tube
and tie them to the tube with the releasable
cable ties (6).
6. Connect the hoses to the sequence valve(7)
with four JIC elbows (5).
7. Connect the two 156" long hoses (8) to the
two top ports of the sequence valve with two
elbows (5) and route them to the tongue and
through the hose loop. Use releasable cable
ties sent with assembly to secure hose to
frame.
Operating and Assembly Instructions

8. With the first section in the lowered position,
connect the hoses to the tractor. Be sure the
tractor reservoir is full.
9. With the markers in field position, crack the
hydraulichosefittings located atthe base end
of one of the cylinders. With the tractor at an
idle speed, activate the tractor hydraulics
valve until hydraulic oil seeps out around the
hose end. Tighten the hose end fittings. Repeat this process for the hose at the rod end
of the cylinder. Crack the fittings on the back
side of the sequence valve until hydraulic oil
seeps out. Tighten and repeat for the opposite cylinder.
10. Cycle each cylinder 3 or 4 times slowly. Both
arms should move to the vertical position on
the first moveand then they should lower and
raisealternately asthe hydraulic leveris operated.

2. Foldand unfold the marker(s) slowly in order
to work all the air out of your marker hydraulics. Use caution when folding and unfolding
the marker for the first time, and check for
pinching and kinking of hoses.
!
CAUTION
Never allow anyone near the drill when cycling the
markers.
3. Themarkerhydraulicsystem isequipped with
needlevalvesto controlhowfasteach marker
operates.The needle valves are built into the
sequence valve body. There are two hex adjustment heads, one for raising the markers,
and one for lowering the markers. These are
located on each end of the sequence valve.
To adjustthe speedof each marker,screw the
needle valve clockwise to adjust the raise or
lower marker speed to a low setting. Fold the
markerup and downa fewtimes and recheck
for pinching or collapsing of hoses. With the
tractor engine at an operating rpm, adjust the
needle valve to limit the marker to a safe operating speed. Excessive folding speeds can
cause marker damage.
Adjustments
NOTE:JIC fittings do not require high torque.JICand 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 over tightening
or valve contamination, DO NOT use sealant tape.
