Transport Carrier (2015 and 2515 only)
When marker is folded, the second section should rest in
transport-carrier saddle.
To adjust front-to-rear position of saddle, loosen 1/2-by-6-
inch u-bolts (1) that fasten transport-carrier mount onto
box frame. Slide transport-carrier assembly forward or
back as needed.
To adjust height of saddle, loosen 1/2-by-2-inch u-bolts (2)
that hold carrier tube to mounting bracket. Slide carrier
tube up or down as needed. Refer to Figure 3-21.

Bleeding Marker Hydraulics
To fold properly, the marker hydraulics must be free of air.
If the markers fold in jerky, uneven motions, follow these
steps.
!
CAUTION!
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.
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be
almost 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.
1. Check that tractor hydraulic reservoir is full.
2. With both markers lowered into field position, loosen
hydraulic-hose fittings at rod and base ends of marker
cylinders. If applicable, loosen fittings on back side of
sequence valve.
3. With tractor idling, activate tractor hydraulic valve until
oil seeps out around a loosened fitting. Tighten that fit-
ting.
4. Reactivate tractor hydraulic valve until oil seeps out
around another loosened fitting. Tighten that fitting.
Repeat process until all loosened fittings have been
bled and tightened.
IMPORTANT: Never bleed an O-ring fitting. Instead,
bleed a nearby pipe or JIC 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 cracking hydraulic fittings from
over tightening, do not use plastic sealant tape.
