INSTALLATION
HYDRAULIC SYSTEM - General
The main lift cylinders on wing fold models are
connected in a series circuit. Each cylinder has a
different diameter, with the smaller called a “slave”
and the larger a “master”. Both cylinders have a
bypass port at the rod end, allowing air to be purged
from the system when the cylinders are completely
extended.
For the implement to raise and lower evenly and be
level, all cylinders must extend and retract the same
distance (within ± 1/4”). If the implement raises
unevenly, purge the air from the hydraulic system.
Note: “Purging air” from the system is the same
procedure as “charging” the system with fluid.
PURGING AIR FROM HYDRAULIC
SYSTEM - Initial Assembly
IMPORTANT! Cylinder operation will be very erratic
and uneven until all air is purged from main lift and
wing fold circuits.
Note: Procedures below are normally used upon
initial machine assembly and after major
disassembly of hydraulic circuit(s).
Main Lift Circuit
1. With rod ends of lift cylinders disconnected,
slowly extend cylinders. When fully extended,
hold tractor valve open for 30 - 60 seconds,
allowing air to purge from system.
2. Fully retract and extend cylinder(s) several times
(usually 3 - 4) to completely purge air from
circuit. Repeat Step #1 as required.
3. Fully extend cylinders and hold valve open for at
least two minutes with maximum flow (tractor at
high idle).
4. When cylinder(s) extend evenly and smoothly,
reconnect cylinders to wheel arms.
5. Slowly raise and lower machine. If cylinders
continue to operate in unison and implement
remains level, circuit is charged with fluid and
air is purged.
6. Check for and correct leaks if required.
7. Add hydraulic fluid to tractor as required.
Wing Fold Circuit
1. With rod ends of wing fold cylinders
disconnected, slowly extend and retract
cylinders. Repeat for several cycles.
2. When cylinders extend and retract evenly and
smoothly, reconnect cylinders to wings.
3. Slowly raise and lower wings. If cylinders
continue to operate smoothly, circuit is charged
with fluid and air is purged.
4. Check for and correct leaks if required.
5. Add hydraulic fluid to tractor as required.
Slicer Lift Circuit - SS7400 Rigid Models
Charge and purge air from the slicer lift circuit using
the same procedure as for the wing fold circuit.
Slicer Lift Circuit - SS7400 Folding Models
Charge and purge air from the optional slicer lift
circuit using the same procedure as for the main lift
circuit.
Note: Cylinders are the rephasing type.
WARNING! RECHECK FLUID LEVEL IN
TRACTOR RESERVOIR AFTER
CHARGING AND PURGING AIR
FROM HYDRAULIC SYSTEM.
FAILURE TO DO SO CAN RESULT IN
PERSONAL INJURY AND/OR
DAMAGE TO TRACTOR OR
IMPLEMENT. ADD FLUID AS
REQUIRED.
WARNING! TO PREVENT POSSIBLE SERIOUS
INJURY OR DEATH, CLEAR
BYSTANDERS FROM AREA WHEN
RAISING AND LOWERING
IMPLEMENT AND/OR WINGS.
