5.10.5 Header and Reel Hydraulics
Hoses and Lines
Check hydraulic hoses and lines daily for signs of leaks.
Figure 5.195: Hydraulic Pressure Hazard
WARNING
• Avoid high-pressure fluids. Escaping fluid can
penetrate the skin causing serious injury.
• Relieve pressure before disconnecting hydraulic
lines. Tighten all connections before
applying pressure.
• Keep hands and body away from pin-holes and
nozzles which eject fluids under high pressure.
Figure 5.196: Checking Hydraulic Leaks
WARNING
• Use a piece of cardboard or paper to search for leaks.
• If ANY fluid is injected into the skin, it must be
surgically removed within a few hours by a Doctor
familiar with this type of injury or gangrene
may result.
IMPORTANT:
• Keep hydraulic coupler tips and connectors clean. Dust, dirt, water, and foreign material are the major causes of
hydraulic system damage.
• DO NOT attempt to service hydraulic system in the field. Precision fits require WHITE ROOM CARE during
overhaul.
Relief Valve and Overload Settings
Pressure relief valves are preset. Relief points (windrower differential relief setting) vary depending on the attached
header model, size, and options. Refer to Table 5.3, page 395.
If pressure at the main piston pump relief valve reaches the relief setting, the valve opens—producing a high pitch
sound. To decrease the load on the system, reduce ground speed.
An optional load sensor (7.1.5 Pressure Sensor Kit, page 443) may be installed to monitor system pressure. When
the pressure approaches an overload condition, the cab display module (CDM) produces a warning tone and a
flashing pressure reading. If the warning is ignored, the load will continue to rise which causes the relief valve to
