3. Lubricate the tube ends with multi-purpose lithium-
based grease.
4. Remove all plugs and caps from the hydraulic lines
and securely tighten the lines to the cylinder(s).
5. Start the engine.
6. Swing the carriage five times through its full range or
until the operation of the swing carriage is normal
(no jerks or spongy feel).
7. Shut the engine OFF. Check the hydraulic level and
fill as required.
g. Swing Carriage Cylinder Pressure Checking and
Circuit Bleeding
1. Attach a 4000 psi (276 bar) gauge to the test fitting
on the “VG” port of the unloader valve to test the
system pressure. Pressure readings should be
3000
±100 psi (207 ±7 bar). Refer to Section 8.7,
“Hydraulic System Testing.” To check the cylinder
pressure, consult the factory.
2. Center the swing carriage cylinders.
3. Swing the carriage fully left. Hold the joystick at full
swing left for several seconds, then swing the
carriage fully right and hold the joystick at full swing
right for several seconds. Observe the readings on
the gauge during the carriage swinging operations.
4. Center the carriage. While centering the carriage,
check the pressure reading on the gauge.
5. Repeat Steps 3-4 five times.
