Carrier Assembly for 24P drill
To assemble carrier ontodrill frame, refertoFigure 3.
1. Assemble transport-carrier mount (1) on drill
frame. Center mount 46 1/2inches from outside
end of drill frame. Use 1/2 x 6 1/32 x 7-inch ubolts(2), flat washers,lock washersandhexnuts
(3). Slide mount forward so its leading edge is
about 2 1/4 inches ahead of front edge of drill
frame tube.
2. Bolt transport carrier (4) to transport-carrier
mount so top surface of saddle (5) is about
29 1/4 inches above top of drill frame tube. Secure transport carrier with 1/2x2x3-inch
u-bolts (6), lock washers and hex nuts (7).
3. After installing and bleeding hudraulics, transport carrier may require further adjustment.
When folded, the second marker section should
rest in the transport-carrier saddle..

You may be injured if hit by a folding or unfolding
marker. Markers may fall quickly and unexpectedly if
the hydraulics fail. Never allow anyone near the drill
when folding or unfolding the markers.
Escaping fluid under pressurecan have sufficient pressure to penetrate the skin. Check all hydraulic lines
and fittings before applying pressure. Fluid escaping
froma very smallhole can bealmost invisible. Use paper or cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or gangrene
will result.

CAUTION!
!
WARNING!
Great Plains Mfg., Inc.
1. Check that tractor hydraulic reservoir is full.
2. With both markerslowered into fieldposition,
loosenhydraulic-hosefittings at rod and base
endsof marker cylinders.If applicable,loosen
fittings on back side of sequence valve.
IMPORTANT: Neverbleedan O-ring fitting.Instead, bleed a nearby pipe or JIC fitting.
3. With tractor idling, activate tractor hydraulic
valveuntil oilseeps outarounda loosened fitting. Tighten that fitting.
IMPORTANT: 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 crac king hydraulic fittings from over
tightening, do not use plastic sealant tape.
4. Reactivate tractor hydraulic valve until oil
seeps out around another loosened fitting.
Tighten that fitting. Repeat process until all
loosened fitting have been bledand tightened.
5. Adjust markerfolding to a safe speed. Refer
to "MarkerAdjustments" inthe operator’s
manual.
