15 Preparation and Setup
Bleeding Hydraulics
!
WARNING
Escaping fluid under pressure can have sufficient pres-
sure 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 pa-
per 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.
If the implement is being hooked to a tractor for the
first time, the hydraulic system may have to be
purged of air.
1. Check the hydraulic fluid in the tractor reser-
voir and fill to proper level.
Bleeding Transport Cylinders
2.
Back the paddle away from the hydraulic
depth control valve on the implement.
3. With the transport locks installed on the trans-
port cylinders, see “Transporting,” page 30,
crack open the JIC fittings on the rod ends.
Engage the hydraulics to “lower” the imple-
ment until fluid escapes from the loose fit-
tings. Tighten these two fittings.
4. Raise the implement and remove the trans-
port locks. Lower the implement completely.
5. Crack open the JIC fittings on the base end of
the transport cylinders. Engage the hydrau-
lics to “raise” the implement until fluid es-
capes from the loose fittings. Tighten these
fittings.
6. Raise and lower the implement several times
to ensure smooth operation. If the unit raises
unevenly or is not smooth, you may have to
repeat the bleeding procedure.
Bleeding Coulter Cylinders
1.
Start with the implement fully raised to allow
for a full range of coulter frame movement.
2. Lower the coulter frame. Crack the fittings on
the base end of the coulter cylinders. Engage
the hydraulics to “raise” the coulters until fluid
escapes from the loose fittings. Tighten these
fittings.
3. Raise the coulter frame and block it in place
so it cannot lower. Crack the fittings on the rod
end of the coulter cylinders. Engage the hy-
draulics to “lower” the coulters until fluid es-
capes from the loose fittings. Tighten these
fittings.
