Hydraulic Hose Hookup
Great Plains hydraulic hoses are color coded to
help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are
marked with the same color.
Color
Blue
Orange
To distinguish hoses on the same hydraulic circuit,
refer to plastic hose holder. Hose under extended-
cylinder symbol feeds cylinder base ends. Hose
under retracted-cylinder symbol feeds cylinder
rod ends.
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.Check that tractor hydraulic reservoir is
full.
The drill lifting system is equipped with rephasing
type hydraulic cylinders that require a special pro-
cedure for bleeding air from the hydraulic circuits.
Read and follow this procedure carefully. Rephas-
ing type cylinders will not function properly with air
in hydraulic circuit.
1. Check hydraulic fluid in tractor reservoir and
fill reservoir to proper level. Drill-system ca-
pacity is about 1 gallon. Add fluid to system as
needed. A low reservoir level may draw air
back into the system, causing jerky or uneven
cylinder movements.
